Two Becoming One: A Covenant Of Love That Lasts
Friends, family, and honored guests, welcome. Whatever brought you here today, whether you have traveled far or live just down the road, you have gathered to witness something the Bible calls sacred. You are here to watch two people make a covenant before God. That is not a small thing. That is one of the most significant moments a human life can hold.
We are going to spend a few minutes together with two passages of Scripture, one from the very beginning of the Bible and one from near its end, because the story of marriage begins in a garden and it reaches all the way to the church. Let these words shape what we understand about what is happening here today.
What God Saw
Genesis 2:18 opens with a declaration from God himself: "It is not good for the man to be alone. I will make a helper corresponding to him." Notice that this is the first time in the creation account that God looks at something and calls it not good. Everything else, the light, the land, the living creatures, God had pronounced good. But the man standing alone was incomplete. Not broken. Not sinful. Simply incomplete. God designed human beings for companionship, and he designed marriage as the primary covenant expression of that companionship.
Then God does something remarkable. He forms the woman from the man's own side. Not from the dust of the ground as he had formed the man. From the man himself. When the man sees her, he breaks into the first recorded poetry in human history: "This one, at last, is bone of my bone and flesh of my flesh." There is recognition, delight, and belonging all at once. He is not looking at a stranger. He is looking at someone made from the same substance, called to share the same life.
Verse 24 draws the theological conclusion: "This is why a man leaves his father and mother and bonds with his wife, and they become one flesh." Three movements. Leaving. Bonding. Becoming one. Marriage is not simply a social arrangement or a legal contract. It is a covenant that reshapes identity. Two people who were separate now belong to each other in a way that is permanent, public, and profound.
To the two of you standing here: this is what you are doing today. You are not simply signing a certificate. You are stepping into a covenant that God himself designed, one that calls you to leave, to cling, and to become something together that neither of you could be alone.
What Love Looks Like
The second passage, Colossians 3:12-17, does not describe a feeling. It describes a practice. The apostle Paul is writing to people who already belong to Christ, and he tells them how that belonging should show up in daily life. He says: "Therefore, as God's chosen ones, holy and dearly loved, put on compassion, kindness, humility, gentleness, and patience, bearing with one another and forgiving one another if anyone has a grievance against another. Just as the Lord has forgiven you, so you are also to forgive. Above all, put on love, which is the perfect bond of unity."
That phrase, "put on," is important. Paul is not describing emotions that simply rise and fall on their own. He is describing choices. Compassion is something you put on. Kindness is something you put on. Forgiveness is something you put on, especially on the days when it does not come naturally. And above all of these, love, which Paul calls the bond that holds everything else together.
This is the honest and hopeful word for every marriage: covenant love is not a feeling that sustains itself automatically. It is a daily decision, made again and again, to choose the other person. There will be mornings when patience feels thin and forgiveness feels costly. Paul does not pretend otherwise. He simply says: put it on anyway, because the Lord has first done that for you.
And that is where Christ becomes the center of this covenant. Paul closes the passage by saying, "And whatever you do, in word or in deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him." A Christian marriage is not just two people trying hard to be kind. It is two people who have received grace from God and who are learning, day by day, to extend that same grace to each other. The forgiveness you show your spouse is rooted in the forgiveness Christ has already shown you. The patience you practice is drawn from the patience God has had with you. You cannot sustain this covenant on your own strength, and you were never meant to.
A Word To Those Watching
To the families and friends gathered here: you have a role in this covenant too. Not to stand between this couple, but to stand behind them. Pray for them. Encourage them. Be the kind of community that holds a marriage up when the weight of life grows heavy. The church was never meant to be a place where couples are left alone to figure it out. It was meant to be a body that bears one another's burdens.
And if you are here today without a personal faith in Jesus Christ, know this: the love being described in these passages is not just a model for marriage. It is a picture of how God loves you. He saw you in your incompleteness and came near. He bore the cost of forgiveness so you would not have to bear it alone. That is the gospel, and it is for everyone in this room.
A Charge And A Blessing
To the two of you: leave well. Cling faithfully. Become one with courage and grace. Put on love every morning as if it were the first morning. Forgive as you have been forgiven. Build your home on the Word of God and the worship of Christ, and you will have something that outlasts every season.
May the God who designed this covenant keep you, strengthen you, and make your life together a testimony to his faithfulness.
Now, let us witness these vows.
