Saints and Angel Hosts Rejoice is a children’s service that focuses on the songs of believers and angels as recorded in Luke’s gospel. These songs—which are still sung regularly by Christians around the world—speak of God’s promises made and fulfilled, and the joyful heart that responds to God’s faithfulness. The praise and proclamation of these early believers—prompted by the Holy Spirit—are ours as well, who by faith cling to and rejoice in the promises of God.
