D I S C I P L E S H I P  29 Angels do not experience salvation/redemption as do hu- mans, so we have an experiential understanding of God’s grace, forgiveness, and mercy that they don’t. As a result, seeking God’s glory, these are things into which they long to look. So here, God wants to reveal aspect of His character and nature to angelic be- ings in the spiritual realm. Mercy, forgiveness, redemption, rec- onciliation, and restoration are all concepts with which angels are unfamiliar experientially—until God reveals it to them, us- ing us as shining examples. How gracious He is in allowing us to participate in such a massive task! The same idea applies in Ephesians 3:10. The Church is to reveal God’s wisdom through- out the spiritual realm. Let’s link our participation in this work of revelation with the work of the Church, namely the maturation process. To do this, we’ll look at Ephesians 3:9–11 and 4:12–16. Step 4: Examine 4:1–6:20 as an outworking of 1:1–3:11. In 4:1, Paul says, “I therefore, a prisoner of the Lord, urge you to walk in a manner worthy of the calling to which you have been called.…” What exactly is that calling? Here Paul speaks of our calling as one to live together in a way that embodies the cosmic unity God has inau- gurated. This passage thus sets the tone for the remain- der of the letter, and provides the link with what has gone before. That link is made not only in the summa- rizing theme of unity in these verses but specifically in the “therefore” (NIV then) of v 1 which (as at Rom. 12:1) grounds the appeal in the earlier teaching. (NIV has somewhat obscured this; but cf. the other major translations.5 (emphasis mine) 5 Ibid. S. Ephesians 4:1.
