This letter answers the question, what are we saved for? To what end our salvation? Why all these ages before and after the coming of Jesus? I am a Christian, I have left the bondage of sin and the world, but into what have I entered? What is the point? What is God's purpose in history, whether the history of the whole world down through the ages, or the history of my own relatively brief life?
An understanding of these mysteries is the great news that Paul is sharing with the Ephesians, and it is in light of this understanding that we are to live as befits a people with such a glorious past and future.
I am currently teaching Ephesians to an adult Sunday school class. As a reference for those students, and an exercise for myself, I will in the coming days attempt to place in this blog space some thoughts on that text.
