We understand your concern for ### and the situation at hand. Firstly, we commend you for standing on the promises of God and praying according to His will. Let us join you in prayer and also provide some biblical encouragement and guidance.
In addressing the spiritual warfare aspect of your request, we echo the words of the Apostle Paul in Ephesians 6:12 (WEB), "For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world's rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places." Therefore, it is right to put on the whole armor of God and pray for His protection and intervention.
We stand with you in praying for ###, that the Lord would raise a standard against demonic attacks, as you've quoted from Isaiah 59:19. We also agree that any form of occult influence or stronghold would be brought down, as stated in 2 Corinthians 10:3-5, which reminds us that "though we walk in the flesh, we don't wage warfare according to the flesh; for the weapons of our warfare are not of the flesh, but mighty before God to the throwing down of strongholds, throwing down imaginations and every high thing that is exalted against the knowledge of God, and bringing every thought into captivity to the obedience of Christ."
Moreover, we pray for the freedom of those who may have been negatively influenced or harmed by ###'s actions, as you've referenced John 8:36, "If therefore the Son makes you free, you will be free indeed."
However, we must also remember the love and compassion of Jesus Christ, who came to save sinners. In 1 Timothy 2:1-4 (WEB), we are encouraged to make petitions, prayers, intercessions, and thanksgivings for all people, "for kings and all who are in high places, that we may lead a tranquil and quiet life in all godliness and reverence. For this is good and acceptable in the sight of God our Savior, who desires all people to be saved and come to full knowledge of the truth."
Therefore, we pray not only for the cancellation of any negative influences but also for ###'s salvation and transformation in Jesus Christ. We pray that she would come to know the truth and be set free by the power of the Gospel.
Finally, let us remember the importance of praying in the name of Jesus, for it is through His name that we have access to the Father and it is in His name that we find salvation, as Acts 4:12 (WEB) declares, "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved!"
Let us pray together:
Dear Heavenly Father, we come before You in the name of Jesus Christ. We stand in agreement with the prayers offered for ###, that Your Spirit would raise a standard against any demonic attacks, that any occult influences would be cancelled and voided, and that those affected would be set free. But Lord, we also pray for ###'s heart, that she would encounter Your love and truth, leading to her salvation and transformation. May Your will be done in this situation, and may Your name be glorified. In Jesus' name, we pray. Amen.
