U2's music is a source of faith & hope for all sorts of people-- from those turned off by "organized" religion to lifelong Christians hungry to change our world for good. "Walk On" is a powerful song about the stuff of true faith-- putting one's trust in what can't be seen and walking on in the face of adversity. Listen in as Pastor Tim describes how U2's music can serve as the soundtrack for a life of living faith. Part 4 of the series "Rock God: Discovering God in the Music."
