1 Corinthians 6:19

"Know ye not that your body is a temple of the Holy Ghost which is in you?" He did not merely say, "of the Spirit," but, "which is in you;" which was the part of one who also was soothing. And again, explaining himself still further, he added, "which ye have from God." He mentioned Him that gave also, both exalting the hearer and putting him in fear, both by the magnitude of the deposit, and by the munificence of Him that made it. "And ye are not you own." This is not only to abash, but even to force men towards virtue. "For why," says he; "doest thou what thou wilt? thou art not thine own master." But these things he said, not to take away free-will. For so in saying, "All things are lawful for me, but not all things are expedient," he does not take away our liberty. And here again, writing, "Ye are not your own;" he makes no infringement upon freedom of choice, but he leads away from vice and indicates the guardian care of the Lord. And therefore he added, "For ye were bought with a price." "But if I am not my own, upon what ground do you demand of me duties to be done? And why do you go on to say again, 'Glorify God therefore in your body and in your spirit, which are God's?'" What then is the meaning of, "ye are not your own?" And what does he wish to prove thereby? To settle them in a state of security against sin, and against following the improper desires of the mind. For indeed we have many improper wishes: but we must repress them, for we can. And if we could not, exhortation would be in vain.
