Our old man — Coeval with our being, and as old as the fall; our evil nature; a strong and beautiful expression for that entire depravity and corruption which by nature spreads itself over the whole man, leaving no part uninfected. This in a believer is crucified with Christ, mortified, gradually killed, by virtue of our union with him. That the body of sin — All evil tempers, words, and actions, which are the "members" of the "old man," Colossians 3:5, might be destroyed.
