It is never, repeat never, God's will for a Christian to date or marry a non-Christian. There are many reasons for this, but the essence is basic incompatibility on the most fundamental level of life: who, or what, we worship. That's the core issue. Not how handsome of how cute; not how much money or what kind of car he drives. Who, or what, does he or she worship? If you date someone who worships someone or something other than your God, or someone who worships God with only half their heart, sooner or later you will be asked to abandon your convictions. You don't want to do that, do you? If not, don't date or marry anyone who loves anyone or anything more than God, our Father.
Bait Or Believer?
One student asked this question: "If we can't date unbelievers won't they be disappointed with out attitude? Shouldn't we date them so that we can win them to Christ?"
