This is a great mystery; but I speak concerning Christ and the church. Ephesians 5:31-32

The ordinary mind cannot comprehend the fusion of a man and a woman in marriage. It is a great mystery. This Union of man and woman Increases the spiritual strength of the couple. The Bible, speaking in Deuteronomy 32:30, says that one shall chase 1,000 and two shall chase 10,000 Instead of chasing 1,000 as they were as individuals before their marriage, together they shall chase 10,000 when they are married. The fusion of the man and the woman in marriage makes their spiritual strenght increase to such an extent that nothing can be impossible for them to achieve.
