5:9 redeemed. The redemption price (Ephesians 1:7) was paid long ago on the cross, but the work of redemption will only be complete when Satan is cast out and Christ takes full possession of His inheritance. See Luke 21:28; Romans 8:22-23; Ephesians 1:13-14; Psalm 2:5-9.

5:9 nation. Christ said that “the gospel must first be published among all nations” (Mark 13:10), for He does have His elect in every ethnic and linguistic group. They will all be gathered before His throne following the rapture, singing the great song of redemption, as well as that of creation (Revelation 4:11).
