Colossae was probably the least significant city that received a New Testament letter, but to that city Paul wrote the most amazing teachings about our glorious Lord and Savior. And yet his purpose was purely practical: by knowing and worshiping the Lord Jesus Christ, we grow spiritually. In this letter, Paul insists that the true path to spiritual maturity is to fill our minds with the truth of Christ, and let that truth touch our lives, so that we are filled with thanksgiving and joy.
