My dear sister, I will pray for you. But, please read your bible with all confidence. Utilize the power and authority that Christ left us. He gave us power over unclean spirits. You must believe in the power that He has bestowed up YOU. If you truly believe that there is unclean forces attacking your family, take authority over them and place them back into the realm that they have emerged.
Rebuke them, in the mighty name of Jesus Christ. Plead the blood of Jesus against them.
Anoint yourself with blessing oil, go to Christ in deep prayer and supplication. Ask Him for the power and wisdom to defeat the enemy from your spouse and your children.
We must walk the walk of faith, as well as understand what our religion is all about. Christ is authority! Please read: Matthew 10:1, Acts 1:8. Jesus wants us to walk in authority over the evils that plague us. Do you have all confidence is Christ? If so, trust Him to heal your family. Place all of this into His hands, with meaning.

Father God, I call on you today to touch the mind, heart and soul of this dear sister. Guide her and lead her in all righteousness and understanding. Give her power over the enemy that is trying to break up her family. Allow her to receive full wisdom, knowledge and understanding of Your powerful Word. Touch her like You have never touched her before. Give unto her a double portion of Your divine Spirit. May she be renewed in her mind as of this day. Jesus I ask these bounties of our Father's blessings, in Your Holy name. Amen!
