“Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.”
King James Version (KJV)
6:6 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, #Col 3:5|, might be destroyed.
Ro 6:6 Knowing this, that our old man is crucified with [him]. The cross of Christ slew our old sinful nature. The gospel was the power that moved us to trample it down, separate from it, and cling to Christ. When this old nature was crucified, we died to sin. Compare Eph 4:22 Col 3:9. That the body of sin. Sin is conceived of as a living power, with an organism, reigning over us through out bodily members. Might be destroyed. Our death to sin destroys this dominion.
