Children 18:3 Christian rock bands is a Christian punk  band from Morris, Minnesota. This Christian rock bands is composed of homeschooled siblings; David, Lee Marie and Seth Hostetter. The lead vocals are shared by David and Lee Marie. Their band's name refers to the Bible verse Matthew 18:3, "And he said: "I tell you the truth, unless you change and become like little children, you will never enter the kingdom of heaven."I definitely agree. Everyone need to be saved before it’s too late.I thought the title of this band is awesome.
