Paul likened the process of spiritual rebirth to changing our clothes. He said, “But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. Do not lie to one another, since you have put off the old man with his deeds, and have put on the new man who is renewed in knowledge according to the image of Him who created him” (Colossians 3:8-10, NKJV). The Greek word translated put off, apotithemi (ap-ot-eeth’-ay-mee) refers to casting off something such as a garment that is no longer useful or appropriate (G659). Another way of looking at putting off the old man might be to reverse our behavior. Instead of doing what comes naturally to us, we are supposed to do the opposite or what is unnatural for us to do when we become Christians.
Paul said that we are to “put on the new man, which is renewed in knowledge after the image of him that created him” (Colossians 3:10). The Greek word translated put on is enduo. “This word means literally to sink into (clothing), put on, clothe one’s self” (G1746). An illustration of how to put on the new man is Superman, who changed his behavior after he put on his suit with a giant S on its chest. When we reveal our Christian identity to the world, we are putting on the new man and associating ourselves Christ. The Greek word translated renewed in Colossians 3:10, anakainoo (an-ak-ahee-no’-o) is derived from the words ana (G303) and kainos (G2537). Kainos (kahee-nos’) “denotes ‘new,’ of that which is unaccustomed or unused, not ‘new’ in time, recent, but ‘new’ as to form or quality, of different nature from what is contrasted as old” (G2537).
Paul highlighted the importance of acts of love when he said, “But above all these things put on love, which is the bond of perfection” (Colossians 3:14, NKJV). The Greek word Paul used that is translated love, agape (ag-ah’-pay) had its perfect expression among men in the Lord Jesus Christ. “Christian love, whether exercised toward the brethren, or toward men generally, is not an impulse from the feelings, it does not always run with the natural inclinations, nor does it spend itself only upon those for whom some affinity is discovered” (G26). Paul identified Christian love as the bond of perfection. The word that he used that is translated bond, sundesmos (soon’-des-mos) refers back to his comment in Colossians 2:2 about being knit together in love. Sundesmos means “a joint tie, i.e. ligament” and is being used figuratively by Paul to indicate a uniting principle of the Christian faith. Love is the characteristic of a Christian that we exhibit that makes us look like Christ.
