Where's the line between pursuing and just being available?

Ok so... I really like this guy at my church. I don't want to pursue him or ask him out, but I want him to know I'm interested (without being creepily obvious about it). And I'm kinda stuck on where the line is in terms of "Am I pursuing him or am I just being friendly, approachable, and available?"

So I need help. I want to talk to him, but I feel like so far I've just been waiting for him to talk to me. Which has worked a few times, but overall not so much. Partly because the last few times I've seen him at church he's been on worship team and he somehow manages to sneak out the stage door immediately after service. I know I need to trust God's timing, that if there's potential for a relationship then I just need to relax and keep just being myself and focus on God.
But I'm also wondering if he knows I'm interested. I *think* he does, because I'm really not very good at hiding it (though I can't tell if I actually blush as much as I think I do), and because he's caught me staring several times (and vice versa).

Help?
