Ephesus was a church in Asia that was very much Roman, situated in a large city that had lots of competition from pagan religions. Paul gets started by getting ahead of all of that: he establishes God’s plan from the beginning. Certainly Christ’s life and death was not just a cosmic tragedy, the unforeseen death of God’s Son. It had purpose, and in Christ’s becoming man, we become heirs with him. All our royalty is found in him because he humbled himself to become like us.
