I like how simple this is, however I have 2 critiques. 1. It looks a little too cartoony. Make it a little sexier (I know that's not specific but all I can think of). 2. We want some form of Christian symbology. So far I'm only interested in your design and 2 others so great job!
Here's something a little bit sleeker #25. I dropped the runner and added the movement to the cross. It combines the two messages you wanted to convey and gives you a more brandable mark I think. It's tough in general to design a simple silhouetted person that doesn't look cartoony, and I'm sure you're seeing that as more entries roll in.
