|Marriage is a creation of the Almighty. Its purpose is to make us become like Him, Genesis 1:26-28, 31; 2:18-25. God is a family of one Spirit. Faithfulness in marriage, becoming one flesh, teaches us how to become one Spirit with the Almighty, I Corinthians 6:15-20. God joins husband and wife, just as He did Adam and Eve, Matthew 19:1-6. Notice that He made twain. Monogamy (one man and one woman) is the divine rule.
