Marriage is often just a prerequisite that some women impose on men as a condition of getting sex conquest with a woman that is "being difficult" yet is a valuable social or economic prize.
However, God views marriage in a far deeper way, creating the circumstances within which He propagates his condition of Godhood.
9 In the image of his own body, male and female, created he them, and blessed them, and called their name Adam, in the day when they were created and became living souls in the land upon the footstool of God.
God (the status and role) is a productive man/woman couple, just as this scripture portrays the first man and woman joined into one and "called their name Adam". Just as a heavenly couple is called "God", so the mortal man and woman is called Adam. Perhaps this is an lingering tradition that a woman takes her husband's surname upon marriage and become "one flesh".
For the Lord, marriage is a covenant and cleaving bond that creates the Godly condition of a man and woman sealed together toward a potential God themselves.
