Romans 2:17-29

Fair pretenses and a plausible profession may deceive men: but God cannot be so deceived; he sees through shows to realities. He is not a Christian who is one outwardly, nor is the true baptism outward in the flesh. Rather, he is a Christian who is one inwardly, and the true baptism is that of the heart. It is in the spirit, and not in the letter, whose praise is not of men but of God.
