Summary for Rev 15:3-4: 15:3-4 ^h The song of Moses and the Lamb signifies that God’s will is united in the old and new covenants. 15:3 ⁱ The Lord God, the Almighty (see also 1:8 ^j; 4:8 ^k; 11:17 ^l; 16:7 ^m; 19:6 ⁿ; 21:22 ^o): For persecuted Christians, the message that God is all-powerful provides great comfort and security.

• The truth that God is also just and true is the foundation of human integrity in the midst of a confused, unjust, and dishonest world.

• God is the supreme, universal King of the nations, not a localized deity attached to one nation or to a human monarch with limited authority.
15:4 ^p Who will not fear . . . and glorify your name? This rhetorical question (cp. Jer 10:7 ^q) assumes that only a fool would fail to do so (cp. Rev 14:7 ^r; 16:9 ^s; see Pss 14:1 ^t; 53:1 ^u).

• God alone is holy: See Rev 16:5 ^v; Lev 11:44 ^w; 1 Pet 1:16 ^x. God’s holiness is the basis for our worship and salvation.

• All nations will ... worship: Some will be forced to acknowledge God (cp. Phil 2:10-11 ^y), but all will recognize that God’s deeds and judgments have been revealed and are righteous and just.
