But sexual sin is never right: our bodies were not made for that, but for the Lord, and the Lord wants to fill our bodies with Himself.  And God is going to raise our bodies from the dead by His power just as He raised up the Lord Jesus Christ.  Don’t you realize that your bodies are actually parts and members of Christ?  So should I take part of Christ and join Him to a prostitute?  Never!  And don’t you know that if a man joins himself to a prostitute, she becomes a part of him and he becomes a part of her?  For God tells us in scripture that in His sight the two become one person.  But if you give yourself to the Lord, you and Christ are joined together as one person.

That is why I say to run from sex sin.  No other sin affects the body as this one does. When you sin this sin, it is against your own body.  Haven’t you yet learned that your body is the home of the Holy Spirit that God gave you, and that He lives within you?  Your body does not belong to you.  For God has bought you with a great price.  So use every part of your body to give glory back to God, because He owns it. 1 Corinthians

But false teachers are fools - no better than animals. They do whatever they feel like; born only to be caught and killed, they laugh at the terrifying powers of the underworld, which they know so little about; and they will be destroyed along with all the demons and powers of Hell.

That is the pay these teachers will have for their sin.  For they live in evil pleasures day after day.  They are a disgrace and a stain among you.  They revel in deceitfulness while they feast with you.  They commit adultery with their eyes, and their lust is never satisfied.  They make a game of luring unstable women into sin. They train themselves to be greedy; and are doomed and cursed.

These men are as useless as dried-up springs of water, promising much and delivering nothing; they are as unstable as clouds driven by the storm winds.  They are doomed to the eternal pits of darkness.  They proudly boast about their sins and conquests, and using lust as their bait, they lure back into sin those who have just escaped from such wicked living.  “You aren’t saved by being good,” they say, “so you might as well be bad.  Do what you like, be free.”

But these very teachers who offer this “Freedom” from law are themselves slaves to sin and destruction.  For a man is a slave to whatever controls him. And when a person has escaped from the wicked ways of the world by learning about our Lord and Savior Jesus Christ, and then gets tangled up with sin and becomes its slave again, he is worse off than he was before.  It would be better if he had never known about Christ at all than to learn of Him and then afterwards turn his back on the Holy Commandments that were given to him. There is an old saying that “a dog comes back to what he has vomited and a pig is washed only to come back and wallow in the mud again.” That is the way it is with those who turn to their sin. Peter 2
