I am in a very bad situation due to marrying a man who was a nominal Christian. He has a good heart much of the time but he has a dark side. Please pray for our deliverance. I am not asking to be delivered from him, I made a vow and God honors those who keep their word, but please pray for our deliverance from evil spirits at work. Thank you

Lord, please help this person in her marriage. Please guide her and her husband to Your good will for their lives. In the name of Jesus I pray and give thanks. Amen

When Lord's children marry non born again Christian they enter under curse. To have satan as father-in-law is not fun. That man is possible to repent in 40 years or never. About the vow, there is about Lord's people not about mixing people. Therefore as long you are married with non believer you are under curse. See 2 Corinthians 6:14 and furthermore.
Are you willing to wait 40 years or all life for that man to be born again Christian ? Remember samson, because of non believer woman he lost his eyes and was in great pain.
Light has nothing in common with darkness.
Lord please have mercy on this woman and i pray that Your will be done in their life. Amen
