Sexual Immorality is Sinful
What comes out of a person is what defiles them. For it is from within, out of a person’s heart, that evil thoughts come – sexual immorality, theft, murder, adultery, greed, malice, deceit, lewdness, envy, slander, arrogance and folly. All these evils come from inside and defile a person.
Mark 7:20-23 (NIV)
But the things that proceed out of the mouth come from the heart, and those defile the man. For out of the heart come evil thoughts, murders, adulteries, fornications, thefts, false witness, slanders. These are the things which defile the man; but to eat with unwashed hands does not defile the man.
Matthew 15:18-20 (NASB)
Don’t you know that the unrighteous will not inherit God’s kingdom? Do not be deceived: No sexually immoral people, idolaters, adulterers, or anyone practicing homosexuality, no thieves, greedy people, drunkards, verbally abusive people, or swindlers will inherit God’s kingdom. And some of you used to be like this. 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.
1 Corinthians 6:9-11 (HCSB)
Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body. Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your bodies.
1 Corinthians 6:18-20 (NIV)
Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality, idolatry, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, envying, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God.
Galatians 5:19-21 (NASB)
Yet the body is not for immorality, but for the Lord, and the Lord is for the body.
1 Corinthians 6:13b (NASB)
But fornication and all uncleanness or covetousness, let it not even be named among you, as is fitting for saints; neither filthiness, nor foolish talking, nor coarse jesting, which are not fitting, but rather giving of thanks. For this you know, that no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God. Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience. Therefore do not be partakers with them.
Ephesians 5:3-7 (NKJV)
For this is the will of God, your sanctification; that is, that you abstain from sexual immorality; that each of you know how to possess his own vessel in sanctification and honor, not in lustful passion, like the Gentiles who do not know God; and that no man transgress and defraud his brother in the matter because the Lord is the avenger in all these things, just as we also told you before and solemnly warned you. For God has not called us for the purpose of impurity, but in sanctification. So, he who rejects this is not rejecting man but the God who gives His Holy Spirit to you.
1 Thessalonians 4:3-8 (NASB)
See that no one is sexually immoral, or is godless like Esau, who for a single meal sold his inheritance rights as the oldest son.

But for the cowardly and unbelieving and abominable and murderers and immoral persons and sorcerers and idolaters and all liars, their part will be in the lake that burns with fire and brimstone, which is the second death.

But now I am writing you not to associate with anyone who claims to be a believer who is sexually immoral or greedy, an idolater or verbally abusive, a drunkard or a swindler. Do not even eat with such a person.
1 Corinthians 5:11 (HCSB)
It is actually reported that there is sexual immorality among you, and of a kind that even pagans do not tolerate: A man is sleeping with his father’s wife.
1 Corinthians 5:1 (NIV)
Do you not know that your bodies are members of Christ? Shall I then take away the members of Christ and make them members of a prostitute? May it never be! Or do you not know that the one who joins himself to a prostitute is one body with her? For He says, “The two shall become one flesh.”
1 Corinthians 6:15-16 (NASB)
We should not commit sexual immorality, as some of them did—and in one day twenty-three thousand of them died.
1 Corinthians 10:8 (NIV)
I am afraid that when I come again my God may humiliate me before you, and I may mourn over many of those who have sinned in the past and not repented of the impurity, immorality and sensuality which they have practiced.
2 Corinthians 12:21 (NASB)
So I tell you this, and insist on it in the Lord, that you must no longer live as the Gentiles do, in the futility of their thinking. They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts. Having lost all sensitivity, they have given themselves over to sensuality so as to indulge in every kind of impurity, and they are full of greed.
Ephesians 4:17-19 (NIV)
Therefore consider the members of your earthly body as dead to immorality, impurity, passion, evil desire, and greed, which amounts to idolatry. For it is because of these things that the wrath of God will come upon the sons of disobedience, and in them you also once walked, when you were living in them.
Colossians 3:5-7 (NASB)
Beloved, I beg you as sojourners and pilgrims, abstain from fleshly lusts which war against the soul, having your conduct honorable among the Gentiles, that when they speak against you as evildoers, they may, by your good works which they observe, glorify God in the day of visitation.

Now those who belong to Christ Jesus have crucified the flesh with its passions and desires.

Proverbs 14:12 (NASB)
None of you shall approach any blood relative of his to uncover nakedness; I am the Lord. You shall not uncover the nakedness of your father, that is, the nakedness of your mother. She is your mother; you are not to uncover her nakedness. You shall not uncover the nakedness of your father’s wife; it is your father’s nakedness. The nakedness of your sister, either your father’s daughter or your mother’s daughter, whether born at home or born outside, their nakedness you shall not uncover. The nakedness of your son’s daughter or your daughter’s daughter, their nakedness you shall not uncover; for their nakedness is yours. The nakedness of your father’s wife’s daughter, born to your father, she is your sister, you shall not uncover her nakedness. You shall not uncover the nakedness of your father’s sister; she is your father’s blood relative. You shall not uncover the nakedness of your mother’s sister, for she is your mother’s blood relative. You shall not uncover the nakedness of your father’s brother; you shall not approach his wife, she is your aunt. You shall not uncover the nakedness of your daughter-in-law; she is your son’s wife, you shall not uncover her nakedness. You shall not uncover the nakedness of your brother’s wife; it is your brother’s nakedness. You shall not uncover the nakedness of a woman and of her daughter, nor shall you take her son’s daughter or her daughter’s daughter, to uncover her nakedness; they are blood relatives. It is lewdness. You shall not marry a woman in addition to her sister as a rival while she is alive, to uncover her nakedness. Also you shall not approach a woman to uncover her nakedness during her menstrual impurity. You shall not have intercourse with your neighbor’s wife, to be defiled with her. You shall not give any of your offspring to offer them to Molech, nor shall you profane the name of your God; I am the Lord. You shall not lie with a male as one lies with a female; it is an abomination. Also you shall not have intercourse with any animal to be defiled with it, nor shall any woman stand before an animal to mate with it; it is a perversion. Do not defile yourselves by any of these things; for by all these the nations which I am casting out before you have become defiled. For the land has become defiled, therefore I have brought its punishment upon it, so the land has spewed out its inhabitants. But as for you, you are to keep My statutes and My judgments and shall not do any of these abominations, neither the native, nor the alien who sojourns among you (for the men of the land who have been before you have done all these abominations, and the land has become defiled); so that the land will not spew you out, should you defile it, as it has spewed out the nation which has been before you. For whoever does any of these abominations, those persons who do so shall be cut off from among their people. Thus you are to keep My charge, that you do not practice any of the abominable customs which have been practiced before you, so as not to defile yourselves with them; I am the Lord your God.
