After the Hebrew slaves passed safely through the Red Sea, Moses and Miriam led them in a song of praise to God on the far shore of the sea. It is referred to as the song of Moses (Exodus 15:1-18). John, in his vision of the saints saved during the Tribulation (Revelation 12:11), saw those saints also standing beside a sea—“like a sea of glass mingled with fire” (Revelation 15:2, ESV). They were singing “the song of Moses, the servant of God, and the song of the Lamb” (Revelation 15:3-4) in praise to God for His deliverance of them through His judgments on the earth.

Jews today still sing the song of Moses, their great deliverer who rescued them from destruction in Egypt. Just as Tribulation saints will sing praise to God for His deliverance of them, so it is incumbent upon Christians today to sing praises to God for His deliverance of them from the destructive power and penalty of sin.

Consider incorporating Revelation 15:3-4 into your own personal times of devotion.

Salvation is not deliverance from hell alone; it is deliverance from sin.
Charles Spurgeon
