The Bible starts and ends with a marriage.
Natural history begins and ends the same way.
As God's creation it is our beginning and end as well. Rebekah Genesis 24 records the story of Abraham sending his servant out to retrieve a bride for his son. This story is widely accepted as allegorical to the Father sending out His servant, the Holy Spirit, to retrieve a bride for His Son. I simply want to point out the story for you to read, I'm not going to develop the ideas here. Ruth The book of Ruth, while a real historical event, is purely allegorical from beginning to end.
