Should I Date an Unbeliever?
The answer to this question is simply no. The bible does not permit the marriage of a believer to an unbeliever and thus it can be concluded a partnership in dating is also wrong. This is both because of the purpose for dating, namely finding a spouse, and the fact that it is more likely that the unbeliever will negatively influence the believer than otherwise. So called evangelistic dating is dangerous, an unbiblical way to evangelize (talk about mixed motives for conversion!), and seldom effective. In fact, usually it is destructive to the believers walk with God and their purity. The proverbs rightly state that a person walking with God should not allow themselves to be seduced, even in their own mind, with the beauty of a person who does not know God (cf. Pro. 6:24 above).
NIV 2 Corinthians 6:14-17 Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness? What harmony is there between Christ and Belial? What does a believer have in common with an unbeliever? What agreement is there between the temple of God and idols? For we are the temple of the living God. As God has said: "I will live with them and walk among them, and I will be their God, and they will be my people." "Therefore come out from them and be separate, says the Lord. Touch no unclean thing, and I will receive you."
NIV Ephesians 5:7 Therefore do not be partners with them.
NIV 1 Corinthians 15:33 Do not be misled: "Bad company corrupts good character."
NIV 1 Corinthians 7:39 A woman is bound to her husband as long as he lives. But if her husband dies, she is free to marry anyone she wishes, but he must belong to the Lord.
(This is from a sermon I did on dating in a Q&A format. There are several of these notes. Please don’t take them out of context. Also, some of these are gray areas in which I have given my opinion. I do not intend to condemn anyone. Only the Word of God can judge the thoughts and intentions of the heart.)
