Bono, of rock band U2, is a God-fearing, bible-believing Christian. However this is not obvious to a lot of people, as he and his band are not outwardly evangelistic. His quote in the book U2 at the End of the World says something about his faith:

“We’ve found different ways of expressing it, and recognized the power of the media to manipulate such signs. Maybe we just have to sort of draw our fish in the sand. It’s there for people who are interested. It shouldn’t be there for people who aren’t.”

Bono’s spiritual beliefs permeate U2’s music, and his activism in social justice issues reveal his faith in action. The messages are there for those tuned in to them, but are subtle and non-preachy enough to not annoy non-believers (otherwise U2 wouldn’t be one of the world’s biggest bands).

The more direct “in your face” confrontational way of expressing faith in music has its place, and many respond to it. However it can alienate other non-believers, without doing much for the spiritually undecided who may be open to Christianity but don’t want it rammed into them. Both approaches are valid, and U2 are a great example of expressing faith in subtle (sometimes even cryptic) ways.
