1 Corinthians 6:15-20

For there is nothing legitimate or natural for you in an appetite which demands such vile institutions and uses for its satisfaction. Your bodies are no longer carnal, they are members of Christ. Shall I take that which is spiritual and convert it into the very opposite, change the limbs of Christ into the flesh of a harlot? “They twain shall be of one flesh,” says Moses (Gen 2:24), and so this awful substitution takes place, and in the place of Christ’s body we find that of a harlot. Such then is their practice, this besetting sin of Corinth. Flee from it. For the One Spirit makes us one with the Lord. That is the truth, of which the other is the lie. Just as in the truth man cannot separate himself from the Lord, for there is but one Spirit, so in the false, in the carnal action, man cannot separate himself from the sin to which he surrenders, he sins not against another only, nor does the wrong of his action merely affect that which is outside himself. He cannot excuse himself by saying “it has nothing to do with my true being, it is inherent in the body only, and I disclaim its connection with me, though as a physical being I am forced by the power of Nature to submit to it, even as I am forced by other appetites to eat and drink!” The reasoning is false. Your bodies are spiritual structures, the spirit that dwells in you is of God, and your bodies are correspondingly spiritual, as temples, rather than animal organisms; they owe allegiance not to the physical self, but to Him who redeemed them at a price. God Himself is to be glorified in your bodies.
