Question: "What does the Bible say about prenuptial agreements?"
Answer: Although prenuptial agreements are not mentioned in the Bible, God does tell us how we are to view marriage, and from that we can figure how agreements such as these would be viewed. First, God intended marriage to be permanent and lasting as long as both spouses are alive. When two Christian people go into a marriage, it should be with the strong belief that divorce is not possible, and it should not even be an option. To have a prenuptial agreement allows for the possibility of divorce. When God formed Eve from Adam's rib, He was signifying the purpose of a husband-and-wife relationship. The woman is the man's helper, taken from under his protective arm and formed from the same flesh. “Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh.” Obviously, this means that separating should not even be contemplated. The only reason divorce was ever allowed was because of sin and people refusing to obey God's Word. “Jesus replied, 'Moses permitted divorce as a concession to your hard-hearted wickedness, but it was not what God had originally intended'” (Matthew 19:8). God never changes, and He despises divorce (Malachi 2:16).
First Corinthians 13:4-7 tells us how we are to love each other. It is not the kind of love that we get excited about, but a conscious decision that we are going to love others the way God loves us. “Love is patient and kind. Love is not jealous or boastful or proud or rude. Love does not demand its own way. Love is not irritable, and it keeps no record of when it has been wronged. It is never glad about injustice but rejoices whenever the truth wins out. Love never gives up, never loses faith, is always hopeful, and endures through every circumstance.” As Christians, we should be making our best effort to show all people this kind of love, but especially to other believers, and definitely to the people we love the most. Ephesians 4:2 says, “Be humble and gentle. Be patient with each other, making allowance for each other's faults because of your love.”
In Ephesians chapter 5, we can learn a lot about the roles of a husband and wife in marriage. Both spouses should submit to each other out of reverence for Christ (v. 21), and the husband has the final authority as Christ does for His church. When the husband is lovingly submitting to the will of Jesus, the wife will in turn lovingly submit to her husband. Husbands are called to love their wives with the same love that Christ showed the church (v. 25). Christ loved the church (all believers) enough to give up His life for us, to sacrifice Himself so that we can be made holy and clean. Just as Christ will never leave us, neither are husbands supposed to leave their wives. Husbands should love their wives as they love themselves, and wives should respect and love their husbands as well (v. 33). Even if we marry someone who is not a Christian or who falls away from God, we are not to leave them because at least they will have a holy example, and the unbelieving spouse may become converted (1 Corinthians 7:10-16).
There is no reason possible that two Christian people who are committed to God and each other should ever need a divorce. Yes, the two people will sin, but God calls us to forgive each other just as He has forgiven us, or else that shows we are not truly His grateful children (Matthew 6:9-15). In society today, we are told that prenuptial agreements are necessary, and anyone who does not enter into one is a fool. But God does not conform to the world; His ways contradict the world's (Luke 16:15, Romans 12:2). None of what the Bible tells us about marriage can fit into the concept of a “just in case we get divorced you can't take my stuff” agreement.
