This is a video from Missions Conference back in October at Lancaster Baptist Church, where Sam is attending college. The song is Reach the World, and the ensemble singing it is composed of missionary kids from around the world who are attending West Coast Baptist College. The solo at the beginning is sung by Sam!
And for those who subscribe via email, which doesn't allow the embedded video, here's the link for you to go directly to the video on YouTube.
Thanks to my friend Jennifer, who attends Lancaster Baptist Church, for sending me the link to this video!
