The Christian life is about both putting off the old-self with its earthly ways and putting on the new-self that is aimed at glorifying God. We see in Colossians 3:12-17 that this "new-creation-attitude" changes how we relate to one another. It gives us the ability to bear with one another, forgive one another, and let the peace of Christ and Word of Christ rule our relationships. And it's all done to the glory of God!
