You have to leave your college buddies, your girlfriends, and everything that can come between you and your new best friend.
24 So a man will leave his father and mother and be united with his wife, and the two will become one body.
The word “united” literally means to be glued together -- “to melt 2 separate entities together to form a permanent bond.” The word you may hear in some weddings is “cleave”. It has the idea of being bonded or welded together. The union is so strong that it takes something extremely violent to dissolve it.
There are four bonds that are to be nurtured between a man and a woman.
The Message Paraphrase says it this way: “Don’t become partners with those who reject God.”
1 Cor 7:12,13 – do not separate. Pray like mad. If you are not yet married please do not consider this as an option.
