Old humanity dies with Christ & becomes new humanity exemplified by Mercy, Generosity, Forgiveness & Love.
Paul teaches us there are two cultural pressures tempting us to compromise our faith: the worship of many gods (that Jesus conquered on the cross) and the observance of the Jewish laws (that He fulfilled). As believers hidden in Christ, we take off the pressures of our culture and rest in the easy yoke of our Savior.
Relationship with Christ is the point and the plan of the gospel. When we have Christ we have everything. Everything we pray about concerns Christ because he is in everything and all things are held together through him.
Paul is imprisoned and writes a letter to a group he has never met and a church he did not found. The church is going well, but experiencing cultural pressure. Paul gives two prayers to the church: 1. Grow in wisdom & understanding. 2. A poem about the Messiah.
