Deaden, therefore, your members on the earth: sexual immorality, uncleanness, passion, evil desire, and greediness, which is idolatry.—Col. 3:5.
“We are to put to death the practices of the past. Several images are used in the New Testament to portray Christian living. The believer is a disciplined “athlete” who strives to win the prize (1 Cor. 9:24–27; 1 Tim. 4:7–9; 2 Tim. 2:5). The believer is a faithful “soldier” who endures hardship to please his commanding officer (2 Tim. 2:3–4). The believer is a tenacious “wrestler” engaged in a fierce struggle with a crafty foe (Eph. 6:12). Here Paul tells us that the believer is to be a ruthless “executioner” who eliminates the behaviors of the past.” – Max Anders
