Lord give the strength and peace to this woman needs, let her see if she ignores what he is doing, and continue praying for his salvation is best. That is better than getting upset or arguing with him, specially if there are children in the household. Father open this man's eyes and touch his heart, may he become the husband and father if he has children this woman deserves. If she has neglected herself have her start making herself look good in his eyes, and maybe he won't be doing what he is doing. She has to look at herself too, plus not be a nagging woman, that is a good way to run our husband away from us into the arms of another woman. Open both their eyes Lord and bring love, understanding, forgiveness, kindness, and harmony into this marriage. I pray in the mighty name of Jesus, amen.
