15 But if the unbeliever departs, let him depart; a brother or a sister is not under bondage in such cases. But God has called us to peace. 16 For how do you know, O wife, whether you will save your husband? Or how do you know, O husband, whether you will save your wife? (1 Corinthians 7:15–16, NKJV)
What if the unbelieving spouse of verses 12-13 is unwilling to be married to a Christian? What if the unbeliever is not willing to accept the trials brought upon the home by the Christian’s faith (1 Cor. 7:26)? Should the Christian yield to the will of the unbelieving spouse and sacrifice faith for the sake of a peaceful marriage? No. We must obey God rather than any person, including a spouse (Acts 5:29). Verse 15 does not give another cause for divorce and remarriage (even though many use it to justify desertion as a cause for divorce and remarriage). Remarriage is not even in this passage. (The married have already been warned against divorce in verses 10-11.) Here, Paul affirms the Christian is not now and never has been in bondage to (a slave to) the unbeliever. God has called us to peace, but not by compromising one’s faith. The unbeliever who demands the believer abandon faith for peace in the marriage demands a price for peace that cannot be paid. If that demand occurs, then “let him (the unbeliever) depart.” You cannot yield your faith and become a slave of men (1 Cor. 7:23). Do you think the unbeliever will be saved by yielding your faith? Resolute faith influences an unbelieving spouse toward salvation (1 Peter 3:1-2).
