And they were singing the song of Moses, the servant of God, and the song of the Lamb: “Great and marvelous are your works, O Lord God, the Almighty. Just and true are your ways, O King of the nations.” —Revelation 15:3

In Revelation 15 the saints who have died for their faith sing the song of Moses and the song of the Lamb. The song of Moses is what the Israelites sang after they were delivered from Pharaoh and safely crossed the Red Sea (see Exodus 15 and Deuteronomy 32). This song will be sung again in heaven. It is the last song in Scripture.

The martyrs in this passage have come through the fire of persecution, yet they have not lost their song. They sing, “Just and true are your ways. . . .” It is an acknowledgment that God knows what He is doing.

There are things in life that don’t make sense. Tragedies befall us. Injustices are committed. Bad things happen, even to Christians. It is at times like these that we need to trust God and honestly worship Him—not because things aren’t going well, but because God is good. We cannot control our circumstances, but we can control our reaction to them.

Job went to bed one night, and everything seemed to be going well. Then he got up the next morning and essentially lost everything he had. Worst of all, he lost his children. And what do we read? “Job . . . fell to the ground to worship. He said, ‘I came naked from my mother’s womb, and I will be naked when I leave. The Lord gave me what I had, and the Lord has taken it away. Praise the name of the Lord!’ ” (Job 1:20–21).

What calamity are you facing? What trial is before you? Worship God, not because of your hardship, but because of His sovereignty and glory. When you get to heaven, it will all be explained. Until that day, we live on promises and not on explanations.
