In Revelation 15:3-4 the angels sing the song of Moses, and sang the song of God’s servant Moses and of the Lamb: “Great and marvelous are your deeds, Lord God Almighty. Just and true are your ways, King of the nations. Who will not fear you, Lord, and bring glory to your name? For you alone are holy. All nations will come and worship before you, for your righteous acts have been revealed.” The song of Moses celebrated Israel’s deliverance from Egypt (Exodus 15). The angels sang this song because it celebrates the deliverance of God’s people from the power of Satan. We should not have to wait until the end times to celebrate the fact that God delivers us through pain and suffering. God is in control and He wants nothing but what is best for us.
