1. The Angels with the Plagues, Ch. 15:1-2a
Seven angels appear, to whom is entrusted the execution of the seven plagues, which are called “the last” because they lead to the end of the world and to the bar of judgment;[495] and the sea of glass, formerly described as “like unto crystal”, now becomes “mingled with fire”, the sign of the flushing of victory through anticipated judgment felt by all those who share in that great boundless life which exists before the throne, and whose experience is symbolized by the sea with its wide relation to the people of God in the past (cf. notes on ch. 4:6).[496]
2. The Victors by the Sea, Ch. 15:2b
The victors over the Beast and his image stand by rather than upon the sea,[497] indicating their close relation to it, having harps of God prepared for tuneful melody. The figure seems to be drawn from the triumph of Israel at the Red Sea, though the significance of the sea cannot be quite the same, for in the old sense 'the sea is no more' (ch. 21:1); it has here become the symbol of the calm and fulness of life and joy in the presence of God.
3. The Song of the Redeemed, Ch. 15:3-4
The united song of all the redeemed before God, (the Adoration Chorus of Moses and the Lamb) who belong [pg 185] alike to the Old Dispensation and the New, to Moses and to Christ, represents the essential unity of faith and life under both parts of God's redemptive plan which is now about to be completed. It is an outburst of praise and adoration addressed to the Lord God, the Almighty, the King of the Ages, whose wondrous works and righteous judgments have been and are about to be made manifest before all nations. The song is the counterpart of the song of deliverance by the shore of the Red Sea, but it has a new and deeper fulness that is consonant with its theme.
