Just love this thought I found in Casey Treat's book:

Faith isn't the hype and excitement. Faith is commitment and holding on in the tough times, and when you come out of it, you'll realise that it wasn't you holding on to God, but it was Him who was holding on to you.

The light is always at the end of the tunnel, but even as we walk through it, we can rest in hope because He'll carry us through!
