...a few questions before marrying.
Is he/she spiritual?
What church will we attend?
What's their viewpoint on stewardship -- tithing?
Do we share common interest and backgrounds?
2 Corinthians 6:14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? And what communion hath light with darkness?
Abraham insisted that his son marry someone from his relatives instead of a pagan Canaanite. God led his servant to a beautiful lady, and she came back with him. Isaac and Rebekah got married the first day they met. Eventually they had twin boys. Isaac favored Esau, the older one, and Jacob was a Mama's boy. Now we have a divided home. Rebekah helps Jacob trick his father to get his blessing. Love grew cold in this marriage. It happens too often.
Married couples should be lovers, friends, and partners. When it's not, God can fix it.
If you want to get married and don't think a good Christian is out there, pray about it like I did.
