V 8-14 All in heaven once more burst out in praise and adoration to God. But now seen as the Redeemer (v. 9). “Lord” by right of creation in chapter 4; “Lord” by right of redemption in this chapter.
V.9-10 The inside group is made up only of redeemed people. They sing saying “Thou art worthy.” They speak directly to Him.
V.11-12 The next circle is the angels, hundreds of millions of them. They speak of the Lord and say “He.” Because they never sinned they don’t know Him as Savior.
V.13 The outside circle — the whole creation; the “Hallelujah” chorus rolls through the universe.
