"Until the Whole World Hears"

I love this song, it always resounds somewhere deep inside me... to sing until the whole world hears. This music video gave me goose bumps.
You know, one of the first things I thought when I saw the Casting Crowns band in the video is, "They're... kind of old." Not really old, of course, just older than a lot of popular contemporary Christian musicians. When I was talking to mom about this song later, I mentioned that the reason I like Casting Crowns so much is they "preach it". There's so much solid truth packed into all their songs. Mom's response?
"That's probably because they're old."
Maybe it takes the wisdom of someone who's experienced more life to write such heart-grabbing, truth-speaking lyrics.
Here it is. Casting Crown's Until the Whole World Hears official music video. Amazing.
