Chevonee, counseling and much prayer is certainly in order for the husband and wife individually and as a couple. His behavior is definitely indicative of the existence of a lust issue that he must first acknowledged. Hopefully he will see the NEED to ask God to purge his heart and mind from sexually llicit thoughts and to give his wife the strength to honor and support him in his struggle for deliverance.
Please understand that I in no way want to give the impression that this brother is not responsible for his actions, but let's be honest that spirit of lust is so prevalent and at some point has touched us all in one way or the other. Maybe we didn't look at pornography, but what about our thoughts etc... (Let's just be honest) Sometimes as women we don't do very much to help the imaginations of men to stay in check, by the conversations that we allow them to have with us, the things that we do and the places we go, and LAWD the things that we WEAR. As you know true deliverance can only be achieved through partnership with God (You must first want to be delivered).
Let's pray for our brother and sister and their family, Satan would love to destroy it. I don't know your friends, but I will join you in interceeding on their behalf, Satan has had to many victories at the family's
expense. Let's join together and pray for this family. And wait for your praise report. I BELIEVE GOD CAN BIND, HEAL AND DELIVER.
