Dude, that sounds like a great idea! I'd love to help if I can. I'm a little outside your age group though. :) Like to consider myself 30 going on 24. LOL. I pray that Father blesses you with all that you do.
I don't know if what I do would be considered "ministry" or maybe it can be. I try to touch the lives of every athlete that I work with. I can do nothing but demonstrate my walk with Christ and be open to their curiousities.
Currently, for myself, I am trying to get together with a couple of other guys I know locally and have a brotherhood with them.
