Family in Distress

Please pray for my son’s relationship with his partner in life and their three children. They are near a breakup and she would be moving out of state with the children. I am the grandpa and I would also be suffering the loss of my grandkids whom I currently see several times a week and try to instill faith in Christ into all their lives. Tough situation to say the least. I so want my son to marry his gal who is a wonderful person and mother, but this is all on the verge of total breakup. Salvation is also need for all involved.
Please pray somehow this family stays together and marriage is consummated. I know Christ is still in the Lord of miracles. May his will be done.
