Scripture places tremendous emphasis on the sanctity of marriage. To understand why God treasures marriage, we need to only look at why God created marriage. God gives us four reasons for this creation right up front, in the book of Genesis.
1. He declares: “Be fruitful and multiply and fill the earth.” God needed the world to be populated and the best way to fulfill His plan was through marriage.
2. God says, “And subdue it and rule over the fish of the sea and over the birds of the sky, and over every living thing that moves on the earth.” In other words, man is to be in partnership with his wife in managing the earth and caring for the environment.
3. “Then the Lord God said, “It is not good for the man to be alone. I will make him a helper suitable for him.'” Humankind’s deep need for companionship is another reason God established marriage.
4. But that’s not all. “For this reason a man shall leave his father and mother, be joined to his wife, and the two shall become one flesh.” God declares that a couple’s bodies are for the joy of their mate, an act that defines marriage as a special relationship.
God is clear – from the very beginning – that marriage is integral to His plan. Which is why He demands that marriage be treated as the sacred treasure that it is.
