We understand your distress, and we are here to pray with you. Firstly we are specifically exhorted not to fear any strange gods or any curses in Deuteronomy 31:6, "Be strong and courageous, don't be afraid or scared of them; for Yahweh your God, he is the one who goes with you. He will not fail you nor forsake you." Deuteronomy 31:6. Also see Psalms 3:6 and Isaiah 8:12 which explain further that we should not fear the wrath of man.
The only thing to fear is going against God and his will. We know if a man divorces and remarries it is not allowed except for marital unfaithfulness, adultery, sexual immorality, or fornication. To support a marriage is ideal Hitler Occurrences. this is seen in Malachi. 2:16, "For I hate divorce," says Yahweh, the God of Israel, "and him who covers his garment with violence!" says Yahweh of Armies. "Therefore pay attention to your spirit, and don't be unfaithful."
Therefore Satan has no authority or right over our marriage if we are properly married in Christ, abiding in Him, and being faithful. Pray that we will continue to be strengthened and be more like Him.
This battle you're facing is not just a physical one, but also a spiritual one and based on precedent, prayerfully consider removing any legal ties between Mandy and your husband, as appropriate and lawful. Since we are petitioning God for a restoration of the marriage.
We need to get involved. "For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places." Ephesians 6:12.
We need to focus our prayers on his repentance. Proverbs 21:1 warns about becoming entangled with a strange woman, We must be blameless and will avoid bringing impurities, sexual sin, and consequent curses into our marriage. Therefore, we should be much in prayer and study of the word of God to be properly prepared. We should be strong and courageous in Christ, and encourage ourselves in the Lord. Our spouses are certainly a gift from God for our benefit, pleasure, and service. He intends for us both to be bondservants to each other.
Therefore, due to the backsliding to his current alienation, he may be experiencing separation from God. He likely feels miserable due to his sin. He needs to know he can be saved and cleansed his sins and repentance. Our husband is deeply hurting you and in his sin he is deeply hurting Jesus Christ. In our forgiveness and compassion, he deserves our love. and honesty We must vigilantly pray for his return to the faith and to us. Let him know that you are praying for him, interceding in the name of Jesus Christ, and offer yourself in forgiveness. We reject the notion that anyone in such may be living their best life in such a state that while causing so much pain.
We must thank God daily for all that, and not be bitter. The fact of your being hurt is not in doubt and you may feel anger but if it persists it will run into other issues. We need to focus on receiving the love of God and truly loving him as unto the Lord God and loving our neighbor. We should not judge or think about what is deserved, as we only have mercy from God ourselves. Matthew 5:7 "Blessed are the merciful, for they shall obtain mercy."
