Jeremiah 17:8 - "For he shall be as a tree planted by the waters, and that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit."
Whenever I think my fear is too great and it's sucking me under, God sends a song like this with a testimony like the one Matt shared at the concert we attended a few years ago, and I can draw strength and comfort from fellowship in God's word with other believers.
