I can't pray for him to come back to live with you but I can pray for you both to be closer to God and each other.
Father, I pray that each of these people will be drawn to You, give themselves over totally to You and Your will. I pray for their salvation and the healing of past hurts. Father, if it is Your will, I pray for this couple to come to know and love You and accept Jesus as their personal Lord and Savior, and then to be able to fully love one another in a christian relationship. In Jesus' name, Amen.
