We are truly heartbroken to hear about the horrific abuse you have experienced. We stand with you in the power of Jesus' name, rebuking the evil that has been committed against you. First, we must emphasize that the behavior you've described is utterly condemned by God. Marriage is designed to be a union of love, respect, and mutual submission, as outlined in Ephesians 5:21-33 (WEB):
"subjecting yourselves to one another in the fear of Christ. Wives, be subject to your own husbands, as to the Lord. For the husband is the head of the wife, as Christ also is the head of the assembly, being himself the savior of the body. But as the assembly is subject to Christ, so let the wives also be to their own husbands in everything. Husbands, love your wives, even as Christ also loved the assembly, and gave himself up for it... Nevertheless, let each one of you also love his own wife even as himself; and let the wife see that she respects her husband."
The actions of your husband are a grievous sin, and the lack of remorse and lying are clear indications of an unrepentant heart. We must also address the failings of your church community. They have ignored your plight and even condoned such behavior, which is a grave offense to God. The Bible tells us to bear one another's burdens (Galatians 6:2) and to stand up for the oppressed (Proverbs 31:8-9).
Let's pray together:
"Father, we come before You in the mighty name of Jesus, lifting up our sister who has endured unimaginable abuse. We plead Your healing and comfort over her life. We pray that You would break the chains of trauma and pain, and bring her into a place of restoration and peace. We rebuke the evil committed against her and pray that You would bring conviction to her husband's heart, that he may repent and turn from his wicked ways. We also pray for the church community, that their eyes may be opened to the truth, and that they would stand up for the oppressed and not tolerate such evil in their midst.
Father, we also pray for justice. We ask that You would bring light into this dark situation, and that the truth would be exposed. We pray for the lies to be silenced, and for the victory of the truth in Jesus' name.
Finally, Father, we pray for the salvation of all involved. We know that it is only by the name of Jesus that we can be saved (Acts 4:12). We pray that all would come to know the saving power of Jesus Christ, that they may turn from their sins and be saved.
In Jesus' powerful name, we pray. Amen."
We urge you to seek safety and support from godly believers who will stand with you in this situation. We also encourage you to reach out to local authorities and services designed to help victims of abuse. Please know that you are not alone, and that God sees your pain and suffering. He is a God of justice and healing, and He will not forsake you.
If your husband is demon possessed or influenced, this is a serious spiritual battle that requires mature Christian believers to intervene and cast out demons. For a person to be free from demons, they must desire to stop behavior that is demonic. Also, prayer and fasting may be needed on behalf of your husband if you desire to stay in marriage with him. Otherwise, separation may be necessary for safety and sanity. However, we must warn that divorce is not an option unless sexual immorality has occurred (Matthew 5:32). However, marriage is a lifelong commitment and should not be broken. We encourage you to seek godly counsel and pray fervently for guidance in this matter.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
