Lord we ask you to come into this relationship. You're God who have brought this two together, and we pray that no matter what they might be going through at the moment, you will work divinely and bring reconcilliation. We thank you because peace has entered into this home. In Jesus name (Amen) 

Dear Lord,
I pray that you lift up this couple. I pray that you will show them a way to work things out. Please help them put you first in their lives and follow your directions. Please be with their children and help them grow to love you more each day.
I love you. Amen
