How to make a move on this guy?

Okay, so I'm 14 and there's a cute guy who I think I'm starting to like. He's 17. BEFORE you think, "jailbait" or whatever, we're both committed Christians so sex is out of the question.

He:

-looks at me a LOT. Literally everytime I come near

-kept staring at me from across the school basketball courts one day. We were sitting on the court in different groups and I noticed that he and his friends were staring at me. Then he turned around and sat with his back to me, but his friends kept looking.

-made a guy move to the back of the line when he tried to push in front of me at the cafeteria.

-highfived me after doing the above ^

We barely ever talk, but he looks at me a lot.

I don't want anything serious but I want to make a move. What can I do that is subtle but cute?
