It is significant that this mighty accolade of praise to God from the elders (representing all the redeemed) centers first on Him as Creator, then later on Him as Redeemer (Revelation 5:9). It is proper that our earthly worship and praise should follow this same pattern. The redeemed ones by this time will have received their crown rewards, as well as "praise and honour and glory" (1 Peter 1:7), but then they will "cast their crowns" before Him (Revelation 4:10), acknowledging that only He is truly worthy to receive "the glory and the honor and the power" (the article is in the original Greek). They were merely His creations, and all they might have accomplished on earth was by His grace.
