How do we know God created marriage?

The creation of marriage is explicitly described in Genesis 2:21-25, where God created a woman from the man and introduced her to him. This act illustrates God's intention for companionship and partnership in human life. Furthermore, the repeated emphasis on the unity between man and woman points to God's sovereign design. The Gospel writers and apostles consistently cite this creation narrative to reinforce the sanctity and indissolubility of marriage, indicating that it is instituted by God Himself as part of His divine order.
