We are deeply touched by your request, Thirkad, and we stand with you in prayer for your children, Gage and Havyn. Let's bring your concerns before the Lord, seeking His healing and comfort for both of them. We are praying this all In Jesus Name (IJN) as that is the only way we are saved and come to the Father. He said: I am the way, the truth, and the life. No one comes to the Father except through Me. John 14:6
Firstly, we commend your faith in bringing your concerns to the Lord. We know that God loves Gage and Havyn deeply, and He desires for them to be healed and whole. We remember the words of Jesus in Matthew 19:26 (WEB), "With God all things are possible." This includes healing for Havyn and the ability for Gage to speak. The first area to look at is healing. Healing is ours through the shed blood of Jesus Christ on the cross for our healing, our health, and strength. By his stripes we are healed. (Isaiah 53:5). The forgiveness of our sins was primary but our healing is right there in the atonement. (Matthew 8:17, 1 Peter 2:24). This means healing is available to your children in Jesus name.
Concerning your 18 year old and 19 year old children. Because of the critical age of your children the enemy may try to use them for their abilities to connect with the spiritual world around them. Schizophrenia and related mental disorders may be due to an organic issue in the brain or may be more of a spiritual nature with the mind targeted by demonic influences. This may come from doors the parents may have opened years ago through such things as alcohol or other drugs, cults, the occult or even sin passed down from previous generations of the family. You must pray to uncover any family curses that may be trying to work on your children. (Iniquity works on a three or four generation curse down the family line.) Sin in a person's life can give evil spirits an opening to cause trouble in someone's life. Pray that the Holy Spirit will show you if there is any activity or behavior that is pleasing to the enemy and cleanse those things out of your families lives. (Exodus 20:5, Numbers 14:18)
Some possible door openings: Any sex outside marriage or with the wrong sex. (Corinthians 6:18, Corinthians 7:2, Colossians 3:5, Galatians 5:19, and many others) Most likely these are not issues in your lives, but we bring them up to see that we are aligned in biblical principle and belief. You must consider that you may need to visit the issue of Deliverance for your children.
Similarly, consult your Pastor and consider contacting other ministries who have experience and understanding of the demonic as a cause for such symptoms. Deliverance may be required for both of your children. Jesus, himself, delivered many such people from such torments. The saints have the power and authority to bring deliverance. The best way to rid your family of the works of the devil is to draw closer to God and cut off the activities of the enemy. Since your children have these problems, the question should be what door has been opened. There are so many activities that open up doors for evil spirits to enter a life. Consider even generational sins and curses. Some open doors include drugs, rejection, abandonment, bitterness, accusations, child abuse, rebellion, occult activities, idolatry, playing with ouija boards, fortune telling and witchcraft, which includes most pagan and even eastern religions. Religions are wrong if they do not support Jesus as God and his resurrection to eternal life with the Father. We even see from Genesis 28 that the ability to see and hear in the spirit can come from generational blessings such as with Joseph. Scriptures detailing curses because of sin can be found throughout the bible. Also consider having the home the children live in blessed, prayed for, and cleansed by your Pastor. If the parents still live in that home it should be cleaned out as well. You must get deliverance from your sins, the effects of your sins and from the enemy. Because of your prayer we believe that you both have already started to walk away from and clean up these things.
Read through and apply Psalm 34:1-22 (Including and especially verse 11), 51:1-19, and 53:1-6 for encouragement and understanding from the bible. Pray for healing as in Isaiah 53:3-6. And of course we would apply John 14:12-14 and 15:7, Matthew 21:22, and Mark 11:22-24. Also a great passage of the bible to draw from is Romans 10:6-13. Remember that healing follows the natural flow of Jesus Christ from asking for salvation through the remission of our sins to then receiving the baptism of the Holy Spirit, the promise of the Father, to finally healing in Jesus name through the laying on of hands. All that we do we do in Jesus name with thanksgiving. The enemy will then be on the run in your families life. Jesus and his Holy Spirit are who we pray to. Jesus is the gateway to God. (John 10:1-16, Acts 1:4 and 2:38)
We, therefore, pray for all these things: Father, in Jesus's name, we stand with Thirkad. We come before you asking for your miraculous intervention. Lord, we ask that you heal Havyn from schizophrenia, and we pray that you enable Gage to speak and grant him freedom from seizures, autism, night terrors, anxiety, and panic attacks. Lord heal both children. Father we pray that Gage and Havyn may come to be baptized by the Holy Spirit, living their lives full of your Spirit. Lead them into lives that honor you. All of this in Jesus's name with thanksgiving. Amen.
Father we pray for Thirkad to receive guidance, understanding, and inspiration from you as they go through this spiritual battle for the lives of their children. Lord may you protect and bless them so that they can minister to their children at this time of need. In Jesus Name.
May God's peace and healing be upon Gage and Havyn, and may He grant you the strength and wisdom to support them in this journey. We stand in faith with you for their healing and restoration as you work on all the things that open doors for evil spirits.
