I pray that God remove all evil influence that attempt to cause division in your marriage, and I pray that God cast out all evil influence of false worship that opposes our Lord Jesus Christ.
I pray that God give you revelation of your power in Him, because He has not given us the spirit of fear, but has given us Power, Love and a Sound mind, 2 Timothy 1:7. No power can oppose us because Jesus our Lord has ascended upon high above all principalities and powers and we sit in heavenly places with Him, and He is head over all things to the church, Ephesians 1:22. Therefore, we stand as, we wrestle not with flesh and blood, but with principalities in high places.
As Jesus said in the prophetic scriptures in Isaiah 50:7, "For the Lord God will help me, therefore shall I not be confounded: therefore have I set my face like a flint, and I know that I shall not be ashamed. 50:8, "He is near that justifies me; who will contend with me? let us stand together: who is mine adversary? let him come near to me. 50:9, Behold, the Lord God will help me; who is he that shall condemn me? lo, they all shall wax old as a garment; the moth shall eat them up.
This is the portion of the enemy who tries to separate covenant marriages that God honors. He hears the prayers of husband for the wife and vise verse, and casts out all evil in Jesus name.
I pray that God's love overflow you and your wife, and that He strengthen you and increase His Power in you that no evil can stay around, but that it must flee. I pray for healing for your wife's pain.
May God bless you!
