Paul wants you to put your old life to death and out on your new life. He applies this to the most central and fundamental part of our lives: our family.
Part of our new life in Christ means taking off our old life and putting on the new one. Here Paul uses the imagery of taking off and putting on clothes.
Life comes with lots of philosophies, and the Colossians are being taught a new philosophy. But Paul is encouraging that there is no secret philosophy, but only the wisdom that comes from knowing and living Christ. So set your hearts on him.
It's finally time to see the tensions the church in Colossae was facing. While they may seem irrelevant to us, I believe we can see we still face these challenges today. For Paul, the solution is simple. We have all we need in Jesus Christ.
