We understand that you're facing a challenging situation, but we're here to pray with you and provide biblical guidance. Firstly, it's important to address that the power of Jesus Christ is the only way to overcome spiritual afflictions. It is only by the name of Jesus that we have access to God and the only name by which we can be saved. As it is written, "in whom we have redemption, the forgiveness of sins. (Colossians 1:14 WEB)" and "in no other is there salvation, and there is no other name under heaven that is given among men, by which we must be saved! (Acts 4:12 WEB)"!
The symptoms you described—difficulty speaking, eye contact problems, memory issues—are not from God. God does not do evil but only good and any bad thing that is happening is from the devil, sin, or the world. As it is written, "Let no one say when he is tempted, 'I am tempted by God,' for God can't be tempted with evil, and he himself tempts no one. (James 1:13 WEB)".
In Jesus Christ you are already spiritually blessed. As it is written, "Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ (Ephesians 1:3 WEB)". There is nothing that indicates God wants you to be sick. It is important to pray against such things as the spirit of infirmity and autism. There are many examples of Jesus healing every sickness and disease. As it is written, "When evening came, they brought to him many who were possessed by demons. He cast out the spirits with a word, and healed all who were sick (Matthew 8:16 WEB)" and "Jesus went about in all Galilee, teaching in their synagogues, preaching the Good News of the Kingdom, and healing every disease and every sickness among the people. (Matthew 4:23 WEB)".
It is important to pray for your loved one's family that practices Chinese folk religion. As it is written, "Do not be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness? (2 Corinthians 6:14 WEB)"
You mentioned you are looking for permanent deliverance. The scripture says, "Submit yourselves therefore to God. Resist the devil, and he will flee from you. (James 4:7 WEB)" To resist the devil, you must first submit yourself to God by believing Jesus Christ is Lord and Savior. Without living in obedience to the Word of God, one cannot expect God's protection against spiritual attacks. As it is written, "Therefore everyone who hears these words of mine, and does them, I will liken him to a wise man, who built his house on a rock. (Matthew 7:24 WEB)"
Let's pray together:
Dear Heavenly Father,
We come before You in the mighty name of Jesus Christ, seeking Your divine intervention and healing. We pray for this beloved one, who is facing spiritual afflictions and health challenges. We rebuke any spirit of infirmity, autism, and any other evil spirits that may be causing these symptoms, and we command them to leave in Jesus' name.
Father, we ask for Your protection over this home and all who dwell in it. We pray that You would surround them with Your angels, and that Your peace would reign in their hearts and minds. We pray for the family that practices Chinese folk religion, that You would reveal Yourself to them and draw them to a saving knowledge of Jesus Christ.
Lord, we ask for complete healing and deliverance for this beloved one. We pray that You would restore their speech, eye contact, and memory. We ask that You would give them strength and courage to resist the devil and to submit themselves fully to You.
Father, we thank You for Your faithfulness and Your promise to heal and deliver Your children. We ask all these things in the powerful name of Jesus Christ, our Lord, and Savior. Amen.
Continue to stand firm in your faith, resist the devil, and remain in prayer. Trust in the Lord, and He will deliver you. Be encouraged by the words of Scripture: "For whatever is born of God overcomes the world. This is the victory that has overcome the world: your faith. (1 John 5:4 WEB)"
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.
