What do you think is the one ingredient that can transform an ordinary marriage into an extraordinary one? McDonald’s has its Big Mac sauce, Shake Shack has its Shack sauce, and even What-A-Burger guards its spicy ketchup recipe. These “secret sauces” give each restaurant its competitive edge. But there’s also a secret sauce to marriage that isn’t secret at all. It’s found in the word love. Now, this isn’t Hollywood’s love that evaporates when your spouse gains weight or loses their job. This is the kind of love described in 1 Corinthians 13, often called “The Love Chapter,” describing the hard work of what real love is and what real love does. As we study it, you can discover the answer to this question: Can two people who fall in love before marriage really stay in love after marriage? The answer depends entirely on what kind of love you’re talking about. The 1 Corinthians 13 kind of love doesn’t quit when your husband forgets your birthday. It doesn’t walk out when your wife criticizes you in front of friends. This is the kind of love that makes it to the finish line, not because it’s easy, but because it comes from the God who never fails.

Ever wondered the secret to marriages that last 60 years? I heard about an elderly couple celebrating their diamond anniversary who shared their story: On their honeymoon at the Grand Canyon, the wife’s mule stumbled, and she said calmly to the animal, “That’s once.” When it stumbled again, she said, “That’s twice.” The third time, she got off and shot the mule right between the eyes. When her husband asked why, she looked him in the eyes and said, “That’s once”—and they never had another major disagreement! While there’s humor in that story, the truth is that God desires for everyone who gets married to truly live happily ever after. When two people get married, it’s God’s will for that marriage to be a happy union instead of a civil war. He wants every marriage to end in celebration, not separation, enjoying marriage, not enduring it. That’s why God’s Word gives us a marriage example through an old love song: It’s King Solomon’s Song of Songs. In this book, you find the four essential keys to building a marriage that lasts.

I heard a story about a daughter who wrote her dad about marrying someone she met online: “We met on eHarmony, became friends on Facebook, had long chats on WhatsApp. He proposed on Zoom.” Her dad replied, “I suggest you two get married on X, have fun on Tango, buy your kids on Amazon, and, when you get fed up with this new husband, just sell him on eBay.” There are lots of views today on what marriage is, but the one opinion that should really matter is that of the One who invented marriage—Jesus. Even though Jesus was single and never married, He knew more about marriage than any marriage counselor because marriage was His idea. When the Pharisees asked Him about divorce, Jesus didn’t answer their question about how to get out of marriage. Instead, He explained why you should stay in marriage. In one simple but unbelievably strong sentence, Jesus taught that in marriage math, 1 + 1 = 1. In this passage, Jesus outlined the three principles you need to guard what God has established and, in doing so, fulfill His purpose in your life.
