Setting our affection on the things above means this is where the Christ has preeminence over all things.This is the atmosphere of the throne- Christ all and in all. We know the world below demands we live according to its atmosphere: religion, human government, politics, education, culture, philosophy, sports, etc. all set a tone that is not according to Christ who is above. There is , however, an atmosphere that we are to enjoy on earth and is called the One New Man, which is not just an alternative to the worlds atmosphere, but rather the unveiling of the mystery hidden through all the previous ages. The New man touches His purpose and desire from eternity past and His goal for eternity future on the earth. The New Man has a visible expression and a testimony of Jesus on the earth. It is an atmosphere where it is impossible for individuality or distinctions to prevail or have a place because Christ is all and in all! (vs.11). Verses 12-15 describe the visible, touchable, tangible atmosphere of this New Man. It is forgiving, loving ,peaceful etc . This is an atmosphere where Christs life is flowing through the saints to all the members. This New Man brings the things above down to the world below. The world sees this atmosphere where Christ flows as a place on earth that sets the tone for Gods purpose and becomes a place that establishes dominion over the worlds atmosphere of religion, human government, politics, education, culture, philosophy, sports, etc. The New Man breathes His disposition, offers His forgiveness, demonstrates His love and arbitrates His peace (12-15). The old man cannot live in this atmosphere because It is cannot thrive. The flesh is exposed and self is terminated. This New Man atmosphere is what God is longing for on the earth today where you live.
