Falling for my coworker… help

I’ve been working closely with this guy for a few months now, and I’m realizing I have legitimate feelings for him and I’m positive he also has feelings for me. We work really well together, enjoy each others company and have similar personalities and humor. Were eachothers “work best friends” I guess you’d say? The issue is he’s not interested in becoming a Christian and I have been a Christian since I was little. Which is frustrating because he has character qualities of a Christian that are attractive to me(eg. honest, hardworking, kind). I enjoy my job and am getting paid well so I’m not leaving it anytime soon but I don’t think this is a good situation for me to be in and I don’t know how to get out of it. Help!!
