The best thing to do is ask the Lord. Pray that He would lead you to the place where He would like you to be. You can pray something like this: "Lord, I ask that Your will be done and that You would lead me to the Christian group of Your choice. I give myself to You during these college years and ask that You make them useful for Your purpose. Lord, gain me in these years, and I pray that I would gain and know You more. Lord, I love You. Thank You. Amen."
Tell me, you whom my soul loves, Where do you pasture your flock? ~ Song of Songs 1:7a
