We are deeply concerned to hear about the spiritual attack you're experiencing. The Bible tells us that our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms (Ephesians 6:12, WEB).
Firstly, we commend you for acknowledging the power in the name of Jesus. It is only through His name that we can be saved (Acts 4:12, WEB) and have authority over evil spirits (Mark 16:17, WEB).
Let's pray together:
"Father, in the mighty name of Jesus Christ, we come before You, seeking Your protection and power. We ask that You reveal the identity of this demonic entity that is troubling Your child. Lord, we know that Your Son, Jesus Christ, has given us authority to trample on snakes and scorpions, and over all the power of the enemy (Luke 10:19, WEB). So, in Jesus' name, we command this demon to leave and never return. We pray for Your healing and peace to fill the void left by this evil spirit. Strengthen Your child's faith, and equip them with Your full armor, so they may stand firm against any further attacks (Ephesians 6:11-18, WEB). We ask this in Jesus' name, Amen."
We encourage you to keep praying and reading the Word of God. Submit yourself to God, resist the devil, and he will flee from you (James 4:7, WEB). Remember, the Lord is close to the brokenhearted and saves those who are crushed in spirit (Psalm 34:18, WEB).
Stay strong in the Lord, and do not be afraid or discouraged, for the Lord your God is with you wherever you go (Joshua 1:9, WEB). If possible, seek out fellowship and support from a local Bible-believing church or community of believers.
