Marriage, according to Matthew 19:6, is far more than a legal contract—it’s a sacred covenant created by God. This verse highlights that when two people marry, they become “one flesh,” united not just physically but spiritually and emotionally. That kind of unity requires real commitment—the kind that shows up when love feels hard, when conflict arises, or when the world tells you to walk away. Commitment in marriage means choosing your spouse daily, honoring your vows, and trusting that what God has joined together is worth protecting.
The Bible doesn’t leave room for casual separation or half-hearted love. Instead, it calls couples to a deeper, covenantal commitment modeled after God’s own unshakable love for us. Whether you’re newly married, years in, or preparing for marriage, understanding this kind of biblical commitment will give your relationship a solid foundation. Keep reading to explore what commitment really looks like day to day, how to overcome challenges, and how to let God strengthen your marriage from the inside out.
Marriage isn’t just a ceremony or a contract. According to the Bible—especially Matthew 19:6—marriage is a covenant. A deep, unbreakable bond between a man and a woman that God Himself joins together. This verse gives us a direct, no-nonsense view of how serious commitment in marriage really is.
“So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.” – Matthew 19:6 (NIV)
Let’s break down what that means and why commitment isn’t just important in marriage—it’s essential.
1. What Matthew 19:6 Really Means
“So they are no longer two, but one flesh…”
This isn’t just poetic language. It’s saying that once you’re married, you’re united on every level—emotionally, physically, spiritually. You and your spouse become a new unit. A team.
“…What God has joined together…”
Marriage isn’t just your idea. It’s not even your pastor’s idea. It’s God’s. He’s the one doing the joining. This means marriage is sacred, and not something to be undone casually.
“…Let no one separate.”
That includes outsiders. But it also includes you. This is a direct warning: don’t walk away from this commitment when things get hard. That’s not how God designed marriage.
2. Why Commitment Is the Foundation of Marriage
If love is the fire in a marriage, commitment is the fireplace. It holds everything together. Without commitment, even strong love will burn out fast.
Here’s what commitment looks like in real life:
- Sticking together when you’re annoyed, stressed, or tired.
- Choosing forgiveness even when you’re hurt.
- Showing up for your spouse even when you don’t feel like it.
- Being faithful in heart, mind, and body.
- Working through problems, not running from them.
A lot of couples think feelings will carry them through. But feelings change. Commitment doesn’t.
3. Biblical Examples of Commitment in Marriage
Adam and Eve
In Genesis 2:24, the Bible says:
“That is why a man leaves his father and mother and is united to his wife, and they become one flesh.”
It’s the same language as Matthew 19:6. From the very beginning, God designed marriage to be a committed, one-flesh union. There was no plan B.
Hosea and Gomer
God told Hosea to marry Gomer, a woman who was unfaithful. And even after she betrayed him, Hosea took her back.
Why? Because Hosea’s commitment mirrored God’s own covenant love for His people.
It’s one of the most powerful images of forgiveness and staying when it would’ve been easier to leave.
4. Commitment vs. Contract
Let’s clear something up.
- A contract says: “If you do your part, I’ll do mine. But if you fail, I’m out.”
- A covenant, like marriage, says: “Even if you mess up, I’m not going anywhere.”
Commitment is covenant thinking.
Jesus didn’t say “Let no one separate… unless they cheat, forget your birthday, or spend too much money.” He said, “Let no one separate.” Period.
That doesn’t mean you tolerate abuse or sin without boundaries (we’ll cover that below). But it means you don’t treat marriage as disposable.
5. Common Challenges to Commitment
Marriage isn’t easy. No one said it would be. But here are some of the biggest things that test commitment—and how to fight back:
1. Unrealistic Expectations
You won’t always feel “in love.” That’s normal. Real love is a choice, not just a feeling. It’s easy to love when things are good. Commitment shows up when things aren’t.
2. Poor Communication
Lack of communication leads to misunderstanding, bitterness, and distance. Be intentional. Talk. Listen. Pray together.
3. Cultural Pressure
The world says, “If it’s not working, walk away.” But marriage isn’t supposed to be disposable. Don’t let culture define what God designed.
4. Unresolved Conflict
Conflict is inevitable. But if you never deal with issues, they pile up. Be humble. Ask for forgiveness. Give it freely.
6. What If Commitment Has Been Broken?
Maybe you’re reading this and your marriage is already struggling. Or maybe you’ve been divorced and feel like this verse no longer applies to you.
Here’s the truth: God is a Redeemer.
Psalm 147:3 says, “He heals the brokenhearted and binds up their wounds.”
If there’s still a relationship, there’s still a chance. Get counseling. Get godly support. Work hard. Pray harder. Healing is possible.
If the marriage has ended, know this: you are not unloved or unusable. God still has a purpose for you. But let this truth guide future relationships—commitment matters deeply to God.
7. Practical Ways to Strengthen Commitment
Here’s how you can keep your marriage rooted in commitment:
Daily
- Pray together (even for 2 minutes)
- Say “I love you”
- Serve each other in small ways
Weekly
- Have a real conversation (not just about bills or kids)
- Go on a date—even if it’s just coffee at home
Monthly/Quarterly
- Check in spiritually—how are we doing with God?
- Evaluate your habits—what needs adjusting?
Yearly
- Set goals together—marriage goals, financial, spiritual, personal
- Take a retreat or getaway—reconnect without distractions
8. Final Thoughts: Marriage Is God’s Work
Matthew 19:6 reminds us that God joins two people together in marriage. That means He’s the one who holds it together. Your job isn’t to try harder alone—it’s to invite Him in.
When you rely on God’s strength, you can face anything together. That’s what real commitment looks like.
“Though one may be overpowered, two can defend themselves. A cord of three strands is not quickly broken.” – Ecclesiastes 4:12
Make God that third strand.
