Are the Jonas Brothers Christians?

*I do not own anything* KEEP THE COMMENTS CLEAN AND POSITIVE* This is a video with evidence of the Jonas Brothers' faith. The song in the background is "Everything" by Lifehouse. I apologize for the audio issues. There's a couple of places I put music on top of other music and the last third of the video is quiter than the rest. But I want everyone to understand the faith that means so much to them and to me.
