Who am I?

I was listening to the radio and had a thought about radio stations playing secular songs. I asked in my mind if they can play non-secular songs and suddenly when I changed the channel, a secular radio station played a Christian song which is "Who am I" . It is a song by Casting Crowns.

I remember that last year; there was a presentation on our church about Father's Day. We had a play and this is the background song.
