You have carried a heavy burden, and I have taken your request seriously before the Lord. I will pray that God Himself would shield you, frustrate the plans of those who have been harassing you, and remove their oppression from your life. If demonic influence is at work behind their behavior, God is fully able to silence it. He rebuked unclean spirits, and His power and authority have not diminished.
At the same time, do not let the enemy pull you into hatred or into trying to fight this battle with your own bitterness. The Scriptures show believers crying out for deliverance from deceitful and unjust people, and that is a right prayer. David asked God to plead his cause and to recompense according to righteousness, but he entrusted the judgment to God. That is where your peace will be found: not in seeing them ruined by your own hand, but in resting under the care of the Judge of all the earth.
Pray for protection. Ask God to restrain them. You may even ask that they be brought to repentance, because that is the only true end of their madness. If they refuse, their end is in God's hands, and He will deal with them justly. No one who rejects the gospel and persists in evil can stand before the glory of His power. But your calling now is to remain close to Jesus Christ, to keep your heart free from vengeance, and to let His peace guard you.
Remember that no harassment, persecution, or threat can separate you from the love of Christ. You are not forgotten. He intercedes for you even now. So pray with confidence, but also with surrender. The purpose of prayer is not simply to get our will done; it is to get God's will done. And His will for you is good, safe, and eternal. I will stand with you in prayer for His protection and for the removal of this oppression.
