Below are ten reasons I refuse to settle for a non-Christian man. It's okay if your reasons are different, but I think the reasons below are some things to think about before you get into your next relationship.
1). The Power of Prayer. Prayer is our communion with God. I want a guy that can talk with God and pray with me. There are times that it becomes difficult for me to even pray for myself, so I want a man who will cover me in prayer and not just well-wishes.
And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people. Ephesians 6:18

Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective. James 5:16
Something else to keep in mind, "Less than 1 percent of couples who pray together daily end their marriages."

2). Spirit Not Flesh. There are many temptations that are present in this current world. A main one is premarital sex. I believe in sexual purity (whether you're virgin or born-again virgin).
“Dear friends, I urge you, as aliens and strangers in the world, to abstain from sinful desires, which wage war against your soul” – 1 Peter 2:11
