You have heard that it was said to the ancients: ‘You shall not commit adultery.’ But I say to you, that anyone who will have looked at a woman, so as to lust after her, has already committed adultery with her in his heart. And if your right eye causes you to sin, root it out and cast it away from you. For it is better for you that one of your members perish, than that your whole body be cast into Hell. And if your right hand causes you to sin, cut it off and cast it away from you. For it is better for you that one of your members perish, than that your whole body go into Hell. (Matthew 5:27-30)

“But,” he said “the things which go out from a man, these pollute a man. For from within, from the heart of men, proceed evil thoughts, adulteries, fornications, murders, thefts, avarice, wickedness, deceitfulness, homosexuality, an evil eye, blasphemy, self-exaltation, foolishness. All these evils procede from within and pollute a man.” (Mark 7:20-23)

And he said to them: “Whoever dismisses his wife, and marries another, commits adultery against her. And if a wife dismisses her husband, and is married to another, she commits adultery.” (Mark 10:11-12)

Everyone who divorces his wife and marries another commits adultery. And whoever marries her who has been divorced by her husband commits adultery. (Luke 16:18)

Do you not know that you are the Temple of God, and that the Spirit of God lives within you? But if anyone violates the Temple of God, God will destroy him. For the Temple of God is holy, and you are that Temple. (1 Corinthians 3:16-17)

Do you not know that the iniquitous will not possess the kingdom of God? Do not choose to wander astray. For neither fornicators, nor servants of idolatry, nor adulterers, nor the effeminate, nor males who sleep with males, nor thieves, nor the avaricious, nor the inebriated, nor slanderers, nor the rapacious shall possess the kingdom of God. (1 Corinthians 6:9-10)

Flee from fornication. Every sin whatsoever that a man commits is outside of the body, but whoever fornicates, sins against his own body. Or do you not know that your bodies are the Temple of the Holy Spirit, who is in you, whom you have from God, and that you are not your own? For you have been bought at a great price. Glorify and carry God in your body. (1 Corinthians 6:18-20)

So then, I say: Walk in the spirit, and you will not fulfill the desires of the flesh. For the flesh desires against the spirit, and the spirit against the flesh. And since these are against one another, you may not do whatever you want. (Galatians 5:16-17)

Now the works of the flesh are manifest; they are: fornication, lust, homosexuality, self-indulgence, the serving of idols, drug use, hostility, contentiousness, jealousy, wrath, quarrels, dissensions, divisions, envy, murder, inebriation, carousing, and similar things. About these things, I continue to preach to you, as I have preached to you: that those who act in this way shall not obtain the kingdom of God. (Galatians 5:19-21)

For those who are Christ’s have crucified their flesh, along with its vices and desires. If we live by the Spirit, we should also walk by the Spirit. (Galatians 5:24-25)

Do not choose to wander astray. God is not to be ridiculed. For whatever a man will have sown, that also shall he reap. For whoever sows in his flesh, from the flesh he shall also reap corruption. But whoever sows in the Spirit, from the Spirit he shall reap eternal life. (Galatians 6:7-8)

Therefore, mortify your body, while it is upon the earth. For because of fornication, impurity, lust, evil desires, and avarice, which are a kind of service to idols, the wrath of God has overwhelmed the sons of unbelief. You, too, walked in these things, in times past, when you were living among them. But now you must set aside all these things: anger, indignation, malice, blasphemy, and indecent speech from your mouth. (Colossians 3:5-8)

For this is the will of God, your sanctification: that you should abstain from fornication, that each one of you should know how to possess his vessel in sanctification and honor, not in passions of lust, like the Gentiles who do not know God, and that no one should overwhelm or circumvent his brother in business. For the Lord is the vindicator of all these things, just as we have preached and testified to you. For God has not called us to impurity, but to sanctification. (1 Thessalonians 4:3-7)

You adulterers! Do you not know that the friendship of this world is hostile to God? Therefore, whoever has chosen to be a friend of this world has been made into an enemy of God. (James 4:4)

For all that is in the world is the desire of the flesh, and the desire of the eyes, and the arrogance of a life which is not of the Father, but is of the world. And the world is passing away, with its desire. But whoever does the will of God abides unto eternity. (1 John 2:16-17)
