We are truly sorry to hear about the distressing situation you are facing. Firstly, we want to remind you that our battle 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. Ephesians 6:12 WEB.
We must stand against such evil influences and put on the whole armor of God. It is only through Jesus Christ that we can find true freedom and be saved from such plots of the enemy. And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved. Acts 4:12 WEB.
The blasphemy and hateful speech against our Lord Jesus is a serious matter. They will have to give an account for every idle word they have spoken. For by your words you will be justified, and by your words you will be condemned. Matthew 12:36-37 WEB.
We advise you to take this matter seriously and take appropriate actions to protect yourself. This includes legal actions, as the law of the land is instituted by God to punish evildoers. Be subject therefore to the higher authorities, for there is no authority except from God, and those which exist are ordained by God.... For rulers are not a terror to good work, but to evil. Do you desire to have no fear of the authority? Do that which is good, and you will have praise from the authority, for he is a servant of God to you for good. But if you do that which is evil, be afraid, for he doesn't bear the sword in vain; for he is a minister of God, an avenger for wrath to him who does evil. Romans 13:1, 3-4 WEB.
Let us pray together for your situation:
Heavenly Father, we come before You in the mighty name of Jesus Christ, seeking Your divine intervention and protection. We pray against the evil forces that are stalking and harassing Your child. We bind the spirits of harassment, manipulation, and control, and we loose the spirits of peace, protection, and freedom. Father, we ask that You would expose the evil deeds of those who are perpetrating these crimes and bring them to justice. We pray that You would fill Your child's heart with Your perfect love, which casts out all fear. Give them the strength and courage to stand against this evil and to take the necessary actions to protect themselves. We ask all of this in the precious name of our Lord and Savior, Jesus Christ. Amen.
Lastly, we leave you with this encouragement: Do not be overcome by evil, but overcome evil with good Romans 12:21. Stand strong in your faith, and know that the Lord is with you.
