We understand that you're seeking protection from various negative influences and individuals, as well as safety for your family including your brother and parents. We commend you for acknowledging Jesus. It's important to always put Jesus Christ at the center of our prayers. First, let's address the concerns you've raised.
We live in a world where evil exists, but as children of God, we have been given authority over these forces through Jesus Christ. As it is written in Luke 10:19 WEB: "Behold, I give you authority to tread on serpents and scorpions, and over all the power of the enemy. Nothing will in any way hurt you." This verse assures us that with God's authority, we can overcome evil.
Regarding protection from difficult people, we should remember that our battle is not against flesh and blood, but against spiritual forces of evil. 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."
In dealing with such individuals, we should put on the full armor of God, standing firm with the belt of truth, the breastplate of righteousness, the shield of faith, the helmet of salvation, and the sword of the Spirit, which is the Word of God.
Concerning witchcraft and manipulation, these are strongly condemned in scripture. Deuteronomy 18:9-12 WEB: "When you have come into the land which Yahweh your God gives you, you shall not learn to do according to the abominations of those nations. There shall not be found with you anyone who makes his son or his daughter to pass through the fire, one who uses divination, one who practices sorcery, or an enchanter, or a sorcerer, or a charmer, or a consulter with a familiar spirit, or a wizard, or a necromancer."
Now, let us pray for you and your family:
Dear Heavenly Father,
We come before You in the mighty name of Jesus Christ, seeking Your divine protection and intervention. We pray for Your hedge of protection around this individual and their family—their brother and parents. Guard them from all evil influences, witchcraft, manipulation, and harmful individuals. Give them discernment to recognize and resist such forces, and the strength to stand firm in their faith.
We rebuke any evil assignments against them and declare that no weapon formed against them shall prosper. We ask that You expose any witchcraft or manipulation, and render them ineffective. Surround them with Your favor as with a shield, and let Your angels encamp around them to keep them in all their ways.
We also pray for their spiritual growth and understanding, that they may know the love of Christ which surpasses knowledge, and be filled with all the fullness of God. We ask that You draw them closer to You, and give them a deeper revelation of who You are.
In Jesus' name, we pray. Amen.
Remember, God is your refuge and strength, a very present help in trouble. Trust in Him, and He will deliver you. Stay strong in your faith, and always pray in the name of Jesus, for there is no other name under heaven given among men by which we must be saved. Acts 4:12 WEB "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
