“Put on your new nature, and be renewed as you learn to know your Creator and become like him. In this new life, it doesn’t matter if you are a Jew or a Gentile, circumcised or uncircumcised, barbaric, uncivilized, slave, or free. Christ is all that matters, and he lives in all of us.” (Colossians 3:10-11 NLT – http://bible.com/116/col.3.10-11.nlt)

Paul is talking to those true believers, who have entered into the truth of Christ, recognizing their death to flesh, world, and the demonic, and fully entering new life to God through Christ, in the power and equipping of The Holy Spirit of God.

In Christ, we have died to sin, so that we may live to life eternal. Our full calling and work is to put off the old self and put on the new as a true example that rightly represents Him and His Kingdom interests. Like dawning a fresh suit of clothing, we are to put on Christlikeness as a cloak. It requires a complete change in our way of thinking, speaking, being, and doing, taking up God’s ways as people after His heart.

“IF THEN you have been raised with Christ [to a new life, thus sharing His resurrection from the dead], aim at and seek the [rich, eternal treasures] that are above, where Christ is, seated at the right hand of God. And SET YOUR MINDS AND KEEP THEM SET on what is above (the higher things), not on the things that are on the earth. For [as far as this world is concerned] you have died, and your [new, real] life is hidden with Christ in God. …now put away and rid yourselves [completely] of all these things: anger, rage, bad feeling toward others, curses and slander, and foulmouthed abuse and shameful utterances from your lips! Do not lie to one another, for you have stripped off the old (unregenerate) self with its evil practices, And have clothed yourselves with the new [spiritual self], which is [ever in the process of being] renewed and remolded into [fuller and more perfect knowledge upon] knowledge after the image (the likeness) of Him Who created it. ….” (Colossians 3:1-17 AMPC)
