Father,
I pray this son and his wife know You and serve You. I pray they belong to You and can rely on the protection of dwelling in the shadow of Your mighty wings wherever they go and whatever they do. Father if that is not the case, please send Your Holy Spirit to awaken them and bring them to that place of repentance and surrender. And then they may know their steps are ordained by God and their future is in Your hands. May Your perfect will be done in both of their lives and their marriage be kept strong through every trial. In Jesus' Name I pray, Amen.
