Those who will come to faith in Jesus as the Messiah during the tribulation will sing a song of Moses and a song of the Lamb. These are Messianic Jews. The song of Moses may refer to the song that the Israelites sang in Exodus 15, a song of deliverance from Egypt. However, now they have believed in the Messiah of whom Moses was only a type. So, they also sing a song of the Lamb, celebrating the One who is both Savior and King. The ones singing this song of Moses and of the Lamb are the focus of the Great Tribulation. For while the seven years of tribulation are a time of judgment, they are also a time of great revival among the Jews who finally embrace Jesus as the Lamb of God. For some of us, the only way to get us to consider faith in Jesus, is to go through a time of tribulation. Many of us have to hit bottom before we will ever look up.
