How can I get him to make the move already?

i know for a fact that me and this guy have a mutual interest in each other, and its been about a year since i really noticed that he was interested in me and vice versa. i only see him about once a week during church, which makes it really difficult to have things move faster.
even from across the room, we will lock eyes and the eye contact feels so intense and meaningful. we both go out of our way to get near each other and make small talk.
today we were in a rare scenario where we had a meetup outside of church with many of the regular attendees also there, and he came up to me while i was alone and he was definitely flirting.
So what can i do to get him to ask for my number? even in a sneaky/subtle way?
i give him all the hints he needs but im going crazy with how long its been going on!
