The Apostle Paul talks about the need to “put off the old man” so we can “put on the new man.” He says, “Lie not one to another, seeing that ye have put off the old man with his deeds; and have put on the new man, which is renewed in knowledge after the image of him that created him” (Colossians 3:9, 10).
What did Paul mean?
It helps to see that the new man is here right now, not somehow coming into being.
