David's story is one that is rooted in God's grace. He believed in the Lord Jesus Christ as a teenager, and that began a spiritual journey—filled with many lessons along the way—that still continues after 50 years. His primary calling is to teach God's Word, and this YouTube channel is one of the ways that he tries to fulfill that calling. In 2003, after more than 20 years of churchplanting, itinerant teaching, and missions service, David founded the ministry of Heaven's Family, a Christian nonprofit organization that is helping to advance Jesus' kingdom and serve the "least of these" (Matt. 25:3146) throughout the world.
