Yes, in some ways making a commitment to Jesus Christ is similar to getting married. There are differences, of course—but both involve a decision to leave our old ways of living and commit ourselves completely to someone else.
Let's look at some of the parallels. Before we'll ever get married, for example, we first have to want to be married—in other words, we have to admit that our life will be better off sharing it with someone else. The same is true of Christ. Before we can ever turn to Him, we have to realize we need Him. We have to admit that we have sinned and need God's forgiveness, and that our life will be better with Christ—both now and eternally.
Then, before we get married, we'll ask ourselves if we truly love the other person—and more important, if they truly love us. The same is true of our relationship with Christ. Once we understand how much He loves us, we'll realize that He will never let us go, and we'll respond with love for Him. He loves us so much that He was willing to give His life for us. The Bible says, "This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins" (1 John 4:10).
Finally, marriage involves commitment—and so does our relationship with Christ. Have you committed your life to Him? If not—or if you are unsure—turn to Him in repentance and faith, and commit your life to Him today.
