We understand that you are seeking prayer for Brian Phe, who has been handed over to Satan for the destruction of his flesh due to his idolatry and obsession with veganism, which has led to insanity and a mixture of religions.
Firstly, we must address that our prayers and intercession are powerful when they are aligned with God's will and in the name of Jesus Christ. As it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'"
In this case, we are reminded of 1 Corinthians 5:5 (WEB), where the apostle Paul delivers a man to Satan for the destruction of the flesh that his spirit may be saved. This was done in the hope of repentance and eventual restoration. Likewise, our prayers should focus on Brian Phe's deliverance, repentance, and salvation.
Let us pray:
"Dear Heavenly Father, we come before you in the name of Jesus Christ to intercede for Brian Phe. Lord, we ask that your Holy Spirit convict him of his idolatry and draw him to repentance. As he has been handed over to Satan, we pray that this experience will not harden his heart but lead him to humility and submission to your will. Break the strongholds of veganism and false religions in his life, and restore his mind and spirit, in Jesus' name.
Father, we ask that Brian Phe finds true freedom and salvation in Jesus Christ alone. Give him a renewed mind and a hunger for your Word. Surround him with godly influences that will lead him to the truth. In all things, we pray that your will be done in his life, and that this experience will ultimately lead to his eternal salvation. In Jesus' name, we pray. Amen."
We encourage you to continue praying for Brian Phe, trusting that God is working in his life, even in this difficult situation. Remember the words of James 5:19-20 (WEB), "My brothers, if among you any is found to err from the truth, and one converts him back, let him know that he who converts a sinner from the error of his way will save a soul from death, and will cover a multitude of sins."
Do not be discouraged, but keep interceding and believing for Brian Phe's deliverance and salvation.
