For me, I go in and play a few Christian songs for an audience, and now I have people come up and not tell me I'm great, but tell me that my music is helping save their lives, helping them in the Lord, and helping them end their vices.

It's pretty simple, pretty obvious: that people's first impressions of people are really a big mistake.
