Hey
I'm no expert, but I know that as a teenager myself that wouldn't appeal to me. Take A look at this. I think that this appeals to a teenage audience very very well. I'm not saying you should copy it exactly, but you could go along those lines.

People need to be able to identify with themselves in these types of things. Also, people who are already not involved in church will not be interested in looking at something with Bible quotes on it as they will most likely believe that it's a load of rubbish.
It may be a good idea to keep one quote on, but people shouldn't be drawn to it initailly they should naturally move onto it if they're interested.
