I hope that 2019 brings you lots of great opportunities to sing about Jesus with children!
To help you on the way, here's a Free Song! It's a song from the "King Seekers" CD, recorded with the HOTSHOTS kids, called "Jesus has a Party!"
It's based on the parties Jesus attends or speaks about in the Gospels - you could even make it the basis for a 4 week series in Sunday School... Here are the links: Listen, Download, Sheet Music
