“And have put on the new man who is renewed in knowledge according to the image of Him who created him.”
“and have put on the new man”
This verse moves on from the negative (“put off,” v.9) to the positive (“put on”).
Since we have put away sin from ourselves and engage in fellowship with Christ, this should arm us against sin. This fellowship is based on constructing an edifice of maturity in Christ.
God wants the Christian to “put on” his new way of life.
Conduct needs to conform to the new status. Every believer is a new man (2 Cor. 5:17). We are new because we hold the same status that Jesus does before God. We are new because we possess the life of Christ. We are new because of our position before God.
As of the moment of salvation, we are a new man regardless of our maturity. Yet this passage goes beyond our newness in Christ. Colossians three deals with development into the character of Christ (Gal. 4:19). This is the application of the Word of God to experience.
The first step in experiencing maturity in Christ is the confession of known sin. Christ has already judged our sins on the cross. Our sins can no longer hinder us from advancing toward maturity. Two important dimensions are involved here: 1) principle — we understand what Christ did for our sins as Christians and 2) the application of that principle (I John 1:9). When we do this, we begin to put on the new man. When we judge the “old man” by the cross, the “new man” is made operative.
We put on the new principle, which is constantly renewed. When we put on the new man, there is constant renewal based on confession. The idea is really — refreshed. We constantly renew ourselves like drinking a cool drink of water when very thirsty. We must constantly drink to refresh our spirituality (Eph 5:26; John 7:37-39).
