I had a circle of friends that were very into the whole Christian rock thing. I know *many* Petra songs to this day.

"God gave rock and roll to you" might have been the most secularly famous. At least, it was used at the end of a Bill and Ted movie. I think the second one. :)

Although my personal favorite song of theirs doesn't appear to be considered one of their biggest hits.

I really don't know/remember a lot of other Christian rock bands, but I think Petra might have been the biggest band (except Stryper which I didn't like and therefore don't remember). So, I remember Petra.

I might remember a bit of others if I heard them, but I can't really recall any off the top of my head.
