You won't "find" that girl... She'll find you, at least, that's how it worked for me. When the right person comes, it'll just happen. As for the girl in bible study, why don't you go out w/ her a few times? I don't mean GO OUT WITH HER, but ... take her on a few dates, tell her you really don't know if you are ready to get serious, but that if she wants to go out, you are in, but don't lead her on, let her know that there are no promises. I figure worse case, you'll end up with a really good friend....
"Be a best friend, tell the truth, and overuse I love you
Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
