This is what's on the back of my Youth Group's T-shirts. I really liked it and alot of other people did too (we had people that don't even go to our church order some of our T-shirts)
Really I didn't make any of this, I just made it into a stamp, but I'm positive my Youth Group won't mind, it's the whole point of the shirts anyway for other people to see
The verse is Matthew 19:26, it might be hard to read on the stamp.
Feel free to use!
