# Sin and Sexual Immorality

Paul answered a church whose members were visiting prostitutes, and his answer is the fullest
account in Scripture of why sexual sin is sin. His answer is about the body: who made it, who bought
it, who lives in it, and who will raise it.

**In one sentence:** Scripture calls every sexual union outside the one-flesh marriage of a man and
a woman sexual immorality, and Paul gives the reason it is sin: your body belongs to the Lord who
bought it and will raise it, and it is joined to Him, so flee immorality and glorify God in your
body.

[![A one-minute comic in 5 panels. Panel 1 (1 Corinthians 6:12-13): two men of Corinth talking in a city street. Caption: "Corinth: what some were saying." A Corinthian says: "All things are lawful for me". Another Corinthian says: "Food is meant for the stomach and the stomach for food". Note: "The quotation marks are the ESV’s reading: Paul quotes them." Panel 2 (1 Corinthians 6:13): Paul standing in a room, holding a scroll. Caption: "Paul answers." Paul says: "The body is not meant for sexual immorality, but for the Lord, and the Lord for the body." Panel 3 (1 Corinthians 6:19-20): three empty crosses on a rise at dusk; a believer in white stands looking up at them. Caption: "The reason: you were bought." Paul says: "You are not your own, for you were bought with a price. So glorify God in your body." Note: "The price: “the precious blood of Christ” (1 Peter 1:18-19)." Panel 4 (Genesis 39:12; 1 Corinthians 6:18): Potiphar's wife, a rich Egyptian woman in white linen with a gold collar, holds Joseph's garment; Joseph runs for the doorway. Caption: "Joseph left his garment in her hand and fled." Paul says: "Flee from sexual immorality." Note: "His reason, settled before: “sin against God” (Genesis 39:9)." Panel 5 (1 Corinthians 6:11): three believers in white robes standing in morning light, arms raised. Caption: "And such were some of you." Paul says: "But you were washed, you were sanctified, you were justified". The point: Your body is the Lord’s: He bought it, He will raise it, and it is joined to Him. So flee, and glorify God in your body (1 Corinthians 6:13-20).](https://the-way.lewy.au/assets/img/comics/sexual-immorality.svg)](https://the-way.lewy.au/assets/img/comics/sexual-immorality.svg)

## Key Takeaways

*(This section follows the [Key Takeaways](https://the-way.lewy.au/about/key-takeaways/) format — see that page for what each part is for.)*

### Lessons about Jesus

- He drew the boundary of sexual life from creation itself: "What therefore God has joined
  together, let not man separate" (Matthew 19:6). Jesus took His answer from Genesis 2:24.
- He bought the body with His own blood (1 Corinthians 6:20; Revelation 5:9), and the believer is
  "joined to the Lord" (1 Corinthians 6:17) with the verb Jesus used for a husband joined to his wife (Matthew 19:5).
- God raised Him bodily, and the same power will raise you (1 Corinthians 6:14). His resurrection
  is the reason your body has a future.

### Memory verses

> ✝️ 1 Corinthians 6:19-20 (ESV)
>
> 19 Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from
> God? You are not your own, 20 for you were bought with a price. So glorify God in your body.

> ✝️ 1 Corinthians 10:13 (ESV)
>
> 13 No temptation has overtaken you that is not common to man. God is faithful, and he will not let
> you be tempted beyond your ability, but with the temptation he will also provide the way of
> escape, that you may be able to endure it.

### Be Transformed

- **Think.** Your body is a person's dwelling place: the Holy Spirit's (1 Corinthians 6:19). What
  you do with it, you do in His house and with Him present.
- **Attitude.** Hold your body as purchased property, cared for on behalf of its Owner. You were
  bought with a price, and the price was Christ's blood (1 Corinthians 6:20; 1 Peter 1:18-19).
- **Do.** Name the place, the screen, the hour or the friendship where temptation reliably meets
  you, and decide now how you will leave it. Joseph's escape took one decision made in advance and
  a pair of legs (Genesis 39:12). Then each morning this week, name that place to God and ask Him
  for the strength to leave it, as Jesus told His disciples: "Watch and pray that you may not enter into temptation" (Matthew 26:41,
  ESV). The flesh is weak, and God is faithful to provide the way of escape (1 Corinthians 10:13).

### Prayer

Father, you made our bodies, and your Son Jesus bought them with His blood. Your Spirit lives in
us, and you have promised to raise us as you raised Him. Teach us to treat what you own as yours.
Where we have sinned with our bodies, wash us as you washed the Corinthians, and give us your strength
to run when temptation comes. Thank you that such were some of us, and that we are washed, sanctified and
justified in His name.

In Jesus' name. Amen.

## What Scripture calls sexual immorality

The New Testament's word is πορνεία (*porneia*, por-NAY-ah, G4202). It occurs 25 times, and its
uses show it to be the umbrella term for every sexual union outside marriage. Four uses fix its
range.

**Incest.** "It is actually reported that there is sexual immorality among you, and of a kind that
is not tolerated even among pagans, for a man has his father's wife" (1 Corinthians 5:1, ESV).
Leviticus 18:8 forbids exactly this union.

**The Law of Leviticus 18.** When the council at Jerusalem asked what Gentile believers must keep,
James named four things: "abstain from the things polluted by idols, and from sexual immorality,
and from what has been strangled, and from blood" (Acts 15:20, ESV). The four correspond to laws
Leviticus 17-18 lays on the sojourner as well as on Israel: sacrifice (Leviticus 17:8-9), blood
(Leviticus 17:10-12), an animal's blood poured out (Leviticus 17:13), and the sexual laws, kept by
"the native or the stranger who sojourns among you" (Leviticus 18:26, ESV). James's next
sentence names Moses, who "is read every Sabbath in the synagogues" (Acts 15:21, ESV). So the
sexual laws of Leviticus 18 are likely, though not certainly, the list behind James's one word:
incest, adultery, same-sex intercourse and bestiality (Leviticus 18:6-23). The other reading takes
πορνεία in its general sense, the sexual sins common among pagans; the NIV Biblical Theology Study
Bible offers both. God's judgment on the land of Canaan was for these: "by all these the nations
I am driving out before you have become unclean, and the land became unclean, so that I punished
its iniquity, and the land vomited out its inhabitants" (Leviticus 18:24-25, ESV). Those nations had
no Sinai covenant, so the standard binds every people.

**Wider than adultery.** Jesus lists the two side by side: "out of the heart come evil thoughts,
murder, adultery, sexual immorality, theft, false witness, slander" (Matthew 15:19, ESV; compare
Mark 7:21). Adultery, μοιχεία (*moicheia*, moy-KAY-ah, G3430), is unfaithfulness to a marriage.
πορνεία is the wider term, and it takes in sex before marriage, sex for pay, and every union
Leviticus 18 forbids.

### The boundary Jesus draws from Genesis 2:24

**Defined from creation.** When Jesus was asked about marriage, He went back past Moses to the
beginning:

> ✝️ Matthew 19:4-6 (ESV)
>
> 4 He answered, "Have you not read that he who created them from the beginning made them male and
> female, 5 and said, 'Therefore a man shall leave his father and his mother and hold fast to his
> wife, and the two shall become one flesh'? 6 So they are no longer two but one flesh. What
> therefore God has joined together, let not man separate."

That is the boundary. One man and one woman, joined by God, become one flesh. Every sexual union
outside it is πορνεία. Hebrews says the same in one sentence: "Let marriage be held in honor among
all, and let the marriage bed be undefiled, for God will judge the sexually immoral and adulterous"
(Hebrews 13:4, ESV).

Jesus also carried the boundary inward: "everyone who looks at a woman with lustful intent has
already committed adultery with her in his heart" (Matthew 5:28, ESV). The sin begins where Matthew
15:19 says every sin begins, in the heart.

### Same-sex intercourse, divorce and idolatry

Three questions sit inside this word and each needs its own study. Same-sex intercourse is named in
Leviticus 18:22, and Paul's vice list includes "men who practice homosexuality" (1 Corinthians 6:9,
ESV). Divorce is a separate question, though πορνεία appears in Jesus' exception (Matthew 5:32;
19:9). And the prophets use harlotry as a picture of idolatry: the Septuagint renders Hosea's
charge against Israel with this same word (Hosea 1:2; 4:12), and Revelation does the same of
Babylon (Revelation 17:2). This study keeps to the sin of the body.

## Two slogans from Corinth

Paul wrote 1 Corinthians from Ephesus, before Pentecost (1 Corinthians 16:8). Chapters 5-7 are
one block about bodies and sex: a man living with his stepmother (1 Corinthians 5:1), believers suing each other
(1 Corinthians 6:1-8), a list of those who will not inherit the kingdom (1 Corinthians 6:9-11), men visiting prostitutes
(1 Corinthians 6:12-20), and then marriage, "because of the temptation to sexual immorality" (1 Corinthians 7:2, ESV). Five of
Paul's ten uses of πορνεία are in these three chapters.

The ESV Study Bible reads 6:12-20 as a response to Corinthian believers who were using prostitutes,
and Paul's argument requires it: "Shall I then take the members of Christ and make them members of
a prostitute?" (1 Corinthians 6:15, ESV). Here is the whole passage.

> ✝️ 1 Corinthians 6:12-20 (ESV)
>
> 12 "All things are lawful for me," but not all things are helpful. "All things are lawful for
> me," but I will not be dominated by anything. 13 "Food is meant for the stomach and the stomach for
> food"—and God will destroy both one and the other. The body is not meant for sexual immorality, but
> for the Lord, and the Lord for the body. 14 And God raised the Lord and will also raise us up by
> his power. 15 Do you not know that your bodies are members of Christ? Shall I then take the members
> of Christ and make them members of a prostitute? Never! 16 Or do you not know that he who is joined
> to a prostitute becomes one body with her? For, as it is written, "The two will become one flesh."
> 17 But he who is joined to the Lord becomes one spirit with him. 18 Flee from sexual immorality.
> Every other sin a person commits is outside the body, but the sexually immoral person sins against
> his own body. 19 Or do you not know that your body is a temple of the Holy Spirit within you, whom
> you have from God? You are not your own, 20 for you were bought with a price. So glorify God in your
> body.

### Whose words are in quotation marks

The ESV prints two lines in quotation marks. Greek has no quotation marks, so the punctuation is
the translators' judgment. The ESV, CSB, NIV and NLT print the quotation marks; the NASB, LSB and
NKJV leave them out. The ESV's reading, followed here, is that Paul is quoting the Corinthians and
answering them. Two things support it. Each slogan is followed at once by
a correction ("but not all things are helpful"; "and God will destroy both"), and Paul quotes "All
things are lawful" again at 1 Corinthians 10:23 with the same qualification. The translations
that use quotation marks differ on where the second slogan ends: the NIV carries "and God will
destroy them both" inside it, as the Corinthians' own words; the ESV, CSB and NLT give that clause
to Paul.

The first slogan sounds like Paul's own teaching on freedom from the Law. Paul agrees with the words
and answers what was being done with them. Some things are unhelpful, and he says, "I will not be
dominated by anything" (1 Corinthians 6:12). A freedom that ends in a habit you cannot leave has turned into its
opposite.

The second slogan is an argument by analogy. The stomach is made for food, and food for the
stomach; both are passing things, so what you feed an appetite has no moral weight. The Corinthians
applied it to sex: the body has a hunger, so meet it. Paul accepts the first half. Food and stomach
both pass away, "God will destroy both one and the other" (1 Corinthians 6:13). Then he breaks the analogy at the
point where it fails.

## The body is for the Lord

"The body is not meant for sexual immorality, but for the Lord, and the Lord for the body" (1 Corinthians 6:13,
ESV). Paul answers the slogan with the purpose God gave the body. The relation runs both ways.

Then comes the reason the body differs from the stomach: "God raised the Lord and will also raise
us up by his power" (1 Corinthians 6:14, ESV). The stomach will be done away with; the body will be raised. Paul
gives a whole chapter to this later in the letter, where the body sown perishable is raised
imperishable (1 Corinthians 15:42-44). Some in Corinth were saying "there is no resurrection of
the dead" (1 Corinthians 15:12, ESV), and a body with no future is easy to hold cheap. Paul's answer is the empty tomb. What God means to raise, He cares about
now.

This shows that God values the human body. He made it, His Son took one, and He will raise it. Your
body belongs to the life to come, and so what you do with it belongs to your life with Him today.

## Joined to Christ

Paul's next step turns on a single verb.

> ✝️ 1 Corinthians 6:15-17 (ESV)
>
> 15 Do you not know that your bodies are members of Christ? Shall I then take the members of
> Christ and make them members of a prostitute? Never! 16 Or do you not know that he who is joined
> to a prostitute becomes one body with her? For, as it is written, "The two will become one
> flesh." 17 But he who is joined to the Lord becomes one spirit with him.

"Joined" in 6:16 and 6:17 translates the same participle, κολλώμενος, from κολλάω (*kollaō*,
kol-LAH-oh, G2853), "to join, to cling, to hold fast." It is the verb Jesus uses when He quotes
Genesis 2:24: the man "will be joined" (κολληθήσεται) to his wife (Matthew 19:5; the Septuagint of
Genesis has the compound προσκολλάω). Behind both stands the Hebrew <span dir="rtl">דָּבַק</span>
(*dāḇaq*, dah-VAHK, H1692), "to cling, to hold fast."

Paul does not cite it, but the Old Testament already used this verb for Israel and its God: "You
shall fear the LORD your God. You shall serve him and hold fast to him" (Deuteronomy 10:20, ESV;
also Deuteronomy 11:22; 30:20; Joshua 23:8). The Septuagint renders Deuteronomy 10:20 with κολλάω.
Scripture had one word for a husband clinging to his wife and for a people clinging to the LORD.

Paul puts the two unions side by side. Joined to a prostitute, a man becomes "one body with her,"
and Paul cites Genesis 2:24 to say so: "The two will become one flesh." Sex makes a union whether
the two intend one or not. The Corinthian man thought he was feeding an appetite. God's word from
creation says he joined himself to a woman. Joined to the Lord, the believer becomes "one spirit
with him." The believer's body is a member of Christ (1 Corinthians 6:15), so the man who goes to a prostitute
takes Christ's members with him. Paul answers that thought with μὴ γένοιτο, "Never!"

This is the ground of the prohibition. Sexual immorality is sin because it joins to someone else a
body that already belongs to Christ.

### The bride and the picture

Does sexual sin defile the image of the bride of Christ? Paul draws the line between marriage and
Christ himself. He quotes Genesis 2:24 at Ephesians 5:31 and says, "This mystery is profound, and I
am saying that it refers to Christ and the church" (Ephesians 5:32, ESV). Earlier in the same
chapter he writes, "sexual immorality and all impurity or covetousness must not even be named among
you, as is proper among saints" (Ephesians 5:3, ESV). To the Corinthians he writes, "I betrothed
you to one husband, to present you as a pure virgin to Christ" (2 Corinthians 11:2, ESV).
Scripture also uses the picture in reverse, for unfaithfulness to God: "as a treacherous wife leaves
her husband, so have you been treacherous to me" (Jeremiah 3:20, ESV); "You adulterous people!"
(James 4:4, ESV). The study [The Harlot and the Bride](https://the-way.lewy.au/last-things/the-harlot-and-the-bride/)
follows that reverse picture to Babylon in Revelation.

The conclusion is this study's reading, though it follows closely: a sexual union outside marriage
tells a false story about Christ's union with the church, a joining with no covenant behind it. The
study [The Bride of Christ](https://the-way.lewy.au/israel-and-church/bride-of-christ/) lays out the betrothal in full.

This shows that God binds Himself to His people by covenant and
keeps it, and He made marriage to show the world what that faithfulness looks like.

## A sin against your own body

> ✝️ 1 Corinthians 6:18 (ESV)
>
> 18 Flee from sexual immorality. Every other sin a person commits is outside the body, but the
> sexually immoral person sins against his own body.

The command is plain. The sentence after it is the hardest in the passage, and its reading is
contested.

The Greek reads πᾶν ἁμάρτημα ὃ ἐὰν ποιήσῃ ἄνθρωπος ἐκτὸς τοῦ σώματός ἐστιν: "every sin that a
person might commit is outside the body." The word "other" is supplied. The ESV, CSB, NASB, LSB and NIV all add
it, and the CSB footnotes it "Lit *Every sin*"; the NKJV leaves it out. Two readings follow.

### Paul's statement, or a third slogan

**Paul's own statement.** Translators who add "other" take the line as Paul's, contrasting sexual
sin with every other sin. Gluttony and drunkenness involve the body too, so on this reading Paul
means that sexual sin is different in kind. The NIV Biblical Theology Study Bible notes that it
alone involves the union of two bodies, and the ESV Study Bible that it is a sin against Christ,
whose member the body is, and against one's own body at once. Proverbs makes a related point about adultery:
"he who does it destroys himself" (Proverbs 6:32, ESV).

**A third slogan.** The line has the same shape as the other two. It is short, general and in the
voice of a principle, and Paul answers it with "but" (δέ). Read this way, "Every sin a person commits is
outside the body" is the Corinthians' claim, that what the body does cannot touch the self. Paul
replies, "but the sexually immoral person sins against his own body." The NIV Cultural Backgrounds
Study Bible mentions this possibility. It fits the passage's pattern of slogan and answer, and it
fits a church that thought the body did not matter. Against it: of the translations compared here
only the WEB prints the line as a quotation (the ESV, CSB, NASB, LSB, NIV and NKJV do not), and it
is longer and more qualified than the two slogans before it.

### Where both readings land

Both readings land in the same place, which is why the passage can be taught confidently while this
line is held loosely. On either reading Paul says that the immoral person "sins against his own
body," εἰς τὸ ἴδιον σῶμα. The sin is done to the body as well as with it. The body that was made
for the Lord, that will be raised, that is joined to Christ, is the very thing being wronged.

Sexual sin wrongs others too: Paul names the brother wronged (1 Thessalonians 4:6), and Malachi the
spouse betrayed, "the wife of your youth, to whom you have been faithless" (Malachi 2:14, ESV).

## A temple bought with a price

> ✝️ 1 Corinthians 6:19-20 (ESV)
>
> 19 Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from
> God? You are not your own, 20 for you were bought with a price. So glorify God in your body.

Earlier in the letter Paul called the church God's temple: "Do you not know that you are God's
temple and that God's Spirit dwells in you?" (1 Corinthians 3:16, ESV). Here he applies the same
picture to each believer's body. The word is ναός (*naos*, nah-OSS, G3485), and the LSB footnotes it
"The inner part of the temple": the sanctuary itself, where God's presence dwelt. Your body is the
place where the Holy Spirit lives. Sexual sin is committed in His house.

Then the reason in commercial language: "You are not your own, for you were bought with a price."
ἠγοράσθητε is from ἀγοράζω (*agorazō*, ah-go-RAD-zoh, G59), the ordinary verb for buying. Paul's
readers included slaves (1 Corinthians 7:21-23), and a bought slave belonged to the master who paid
for him. Paul repeats the purchase at 1 Corinthians 7:23: "You were bought with a price; do not
become bondservants of men" (ESV). He does not name the price in either verse. Peter does: "you were
ransomed ... not with perishable things such as silver or gold, but with the precious blood of
Christ" (1 Peter 1:18-19, ESV), and the song of Revelation 5:9 uses Paul's verb, "by your blood you
ransomed people for God" (ESV).

So the conclusion: "glorify God in your body." Other manuscripts add "and in your spirit,
which belong to God" (CSB footnote). Modern editions print the shorter text, and it keeps the
command on the body, the subject of the whole paragraph.

This shows that God paid for you in full. Your body is His by creation, by purchase and by
indwelling, and He means it to show His glory.

## Flee, and you were washed

Paul's command is a single word: φεύγετε (*pheugete*, FYOO-geh-teh, G5343), "Flee." It is a
present imperative, keep fleeing, and Paul gives the same command to Timothy as a way of life
paired with a pursuit: "So flee youthful passions and pursue righteousness" (2 Timothy 2:22, ESV).
Joseph refused Potiphar's wife "day after day" (Genesis 39:10, ESV). Paul gives the command once more
in this letter: "Therefore, my beloved, flee from idolatry" (1 Corinthians 10:14, ESV). The ESV Study Bible draws the line between the two,
and Israel's history had already joined them. Paul recalls the golden calf, when "the people sat
down to eat and drink and rose up to play," and the plains of Moab, where Israel's men went after
the women of Moab and bowed to their gods: "We must not indulge in sexual immorality as some of them
did" (1 Corinthians 10:7-8, ESV; Exodus 32:6; Numbers 25:1-2).

### Joseph and the way of escape

Fleeing is a strategy of distance. Joseph is the picture. Potiphar's wife "spoke to Joseph day
after day," and his answer was to refuse "to lie beside her or to be with her" (Genesis 39:10,
ESV). When she caught his garment, "he left his garment in her hand and fled and got out of the
house" (Genesis 39:12, ESV). He had already settled why: "How then can I do this great wickedness and sin
against God?" (Genesis 39:9, ESV). Joseph named the sin as one against God before the moment came, and
when it came he ran.

God promises an exit every time: "God is faithful, and he will not let you be tempted beyond your
ability, but with the temptation he will also provide the way of escape, that you may be able to
endure it" (1 Corinthians 10:13, ESV). The way of escape is often a door. The command to flee
means walking through it.

Paul gave the Thessalonians the same instruction as God's will for them: "For this is the will of
God, your sanctification: that you abstain from sexual immorality; that each one of you know how to
control his own body in holiness and honor" (1 Thessalonians 4:3-4, ESV). He closes the paragraph
with the Spirit: "whoever disregards this, disregards not man but God, who gives his Holy Spirit to
you" (1 Thessalonians 4:8, ESV). The God who calls you to holiness gives you His Spirit, the Spirit
who lives in the temple of 1 Corinthians 6:19.

### Such were some of you

Paul's argument in 6:12-20 stands on the verses just before it. After the list of those who will
not inherit the kingdom, headed by "the sexually immoral," he writes:

> ✝️ 1 Corinthians 6:11 (ESV)
>
> 11 And such were some of you. But you were washed, you were sanctified, you were justified in the
> name of the Lord Jesus Christ and by the Spirit of our God.

Some of the Corinthians had been exactly what the list names. Three verbs describe what God had done for them: washed, sanctified, justified, each in the past
tense, each done "in the name of the Lord Jesus Christ and by the Spirit of our God." The command to flee is
addressed to people already washed. Purity in 6:12-20 is the life of the justified, and the call is
to live as what God has already made you.

For a believer who has fallen, the same God remains faithful: "If we confess our sins, he is
faithful and just to forgive us our sins and to cleanse us from all unrighteousness" (1 John 1:9,
ESV). And the One who hears that confession knows the pull of temptation from the inside. He "in
every respect has been tempted as we are, yet without sin," so "let us then with confidence draw
near to the throne of grace, that we may receive mercy and find grace to help in time of need"
(Hebrews 4:15-16, ESV).

Marriage is the place where God gives sexual love freely. Paul's very next chapter tells husband and
wife each to give the other their body (1 Corinthians 7:3-4), and the study [Reading the Song of
Songs](https://the-way.lewy.au/wisdom/reading-the-song-of-songs/) shows how warmly Scripture celebrates that gift. The
command to flee protects something God made good.

## Theological principle

The body belongs to the Lord. God made it for Himself; Christ bought it at the cost of His life;
the Holy Spirit lives in it; and God will raise it as He raised Jesus. A sexual union joins the body
to another person, and God has given one union for that joining, the one-flesh marriage of a man
and a woman, which pictures Christ's faithfulness to His people. Every other union is πορνεία, and
it is sin because it gives away what belongs to Christ and wrongs the body He bought.

This is the doctrine of redemption reaching the body. God has bought you, washed you and filled you
with His Spirit, so you may flee immorality and glorify God in your body.

## Discussion questions

1. **The language.** Paul uses κολλάω, "joined," for a man with a prostitute (1 Corinthians 6:16)
   and for a believer with the Lord (1 Corinthians 6:17), the verb Jesus uses for a husband with his wife
   (Matthew 19:5). What does the one verb in three places say about what sex does?
2. **The text in its context.** Chapters 5-7 move from incest, to lawsuits, to prostitutes, to
   marriage (1 Corinthians 7:2). Why might Paul place "such were some of you. But you were washed"
   (1 Corinthians 6:11) immediately before the command to flee?
3. **Christ.** "You were bought with a price" (1 Corinthians 6:20). How does knowing who paid, and what He paid,
   change the way you think about your own body?
4. **The hard part.** "Every other sin a person commits is outside the body" (1 Corinthians 6:18) may be Paul's
   statement or a Corinthian slogan he answers. What does each reading claim, and what does Paul
   say on both?
5. **Be transformed.** The Corinthians said "Food is meant for the stomach" (1 Corinthians 6:13). What
   slogans does our own culture use to say the body's choices carry no moral weight, and how does
   the resurrection answer them (1 Corinthians 6:14)?
6. **Be transformed.** Joseph decided why he would refuse before the day she caught his garment
   (Genesis 39:9, 12). What is your way of escape (1 Corinthians 10:13), and what would it take to
   decide on it, and pray for strength to take it, before you need it (Matthew 26:41)?
