Is missionary dating biblical?

from the old testament

• God consistently warns His people not to enter close covenant relationships with those who would pull their hearts away from Him. Israel was repeatedly cautioned not to intermarry with surrounding nations because of the strong spiritual influence away from God (Deuteronomy 7:3–4).
• The primary concern of intermarrying is not ethnicity but spiritual direction. The danger was that foreign spouses would “turn your sons away from following Me, to serve other gods” (Deuteronomy 7:4). We are not to missionary date nor marry unbelievers because they will draw us from God.
• Mixed spiritual loyalties repeatedly led to compromise and idolatry in Israel’s history. King Solomon is a clear example: his marriages to foreign wives led his heart away from the Lord (1 Kings 11:1–4).
• God calls His people to covenant faithfulness, where love for Him shapes all close relationships (Exodus 34:12–16).
• The Old Testament pattern shows that influence in close relationships is rarely neutral. Instead, it tends to pull the heart either toward deeper faithfulness or toward compromise (Proverbs 13:20).

from the new testament

• Believers are explicitly warned not to form binding relational partnerships with those who do not share their faith. Second Corinthians 6:14 says, “Do not be unequally yoked with unbelievers.” This establishes a principle of spiritual alignment in close relationships.
• Spiritual unity is the foundation for deep partnership. Paul explains that light and darkness, righteousness and lawlessness, Christ and Belial cannot be harmonized (2 Corinthians 6:14–16).
• Marriage is meant to reflect Christ and the Church; we compromise our faith by joining with those who don't share ours. Believers are called to marry “only in the Lord” (1 Corinthians 7:39). Shared faith is the baseline for covenant relationships.
• The influence of relationships is consistently treated as powerful and formative. “Bad company corrupts good morals” (1 Corinthians 15:33) highlights how close association shapes character over time.
• While Christians are called to share their faith, evangelism for someone you are dating is not wise or biblical. The mission is to share the gospel broadly (Matthew 28:19–20) not to enter spiritually divided romantic relationships hoping to “convert” the other person.

implications for today

Love is a powerful force. So is lust. It's often hard to distinguish between the two as emotions are high and attraction can feel like clarity, even when it’s not. But love can be blinding. That’s why dating someone who is not a believer is dangerous.

While the idea of “missionary dating” sounds noble, Scripture never calls romance a strategy for evangelism; instead, it calls believers to share the gospel clearly while guarding our hearts and obeying God, knowing He has what is best for us. Relationships shape us more than we realize, and over time, they either strengthen our devotion to Christ or slowly erode it through compromise and divided loyalty.

What we bind our lives to will shape the direction of our hearts (Proverbs 13:20). When Israel formed close relationships with those who did not follow the Lord, it didn’t stay “neutral”—it consistently pulled them toward compromise and idolatry (Deuteronomy 7:3–4; 1 Kings 11:1–4). That same principle applies and is why we are warned not to be “unequally yoked” because spiritual unity is the foundation for deep life partnership. Dating an unbeliever is not just a casual decision—it is entering a relational trajectory that assumes lifelong partnership with someone who does not share your ultimate allegiance to Christ.

If you are in a relationship with an unbeliever, the most God-honoring way to reveal Christ is not to continue that relationship. God is not asking you to choose between love and obedience—He is calling you to trust that obedience to Him leads to the deepest and most lasting good.
