We are truly concerned for the situation you are describing. First, we want to ensure that the solution is sought in the name of Jesus Christ, as it is only through His name that we have access to God and can be saved (Acts 4:12).
In the Bible, we are told to be sober-minded and watchful, for our adversary the devil prowls around like a roaring lion, seeking someone to devour (1 Peter 5:8). However, we are also assured that God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it. (1 Corinthians 10:13)
Jesus himself said to his disciples in Luke 10:19, "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."
We need to pray for the person being attacked, that God would protect them and deliver them from this evil spirit. However, it is also important to consider that God has called us to be wise and discerning. If there is a spirit asking for money, it is not from God, for our God does not need anything from us, but rather He gives to us abundantly and freely. We need to examine if there is any sin or ungodly activity that may have opened the door for this spiritual attack.
Let us pray together:
Dear Heavenly Father,
We come before You in the mighty name of Jesus Christ, seeking Your divine intervention and healing for this person who is being haunted and attacked by an evil spirit. We plead the blood of Jesus over their life and command this spirit to flee in Jesus' name.
Father, we pray for their swollen arm to be healed and for complete restoration of their health. We also pray for Your guidance and wisdom, that any ungodly activity or sin may be revealed and confessed, closing any open doors for the enemy's attack.
Lord, we ask for Your protection and provision. We know that You are a good Father who cares for His children and supplies all their needs according to Your riches in glory (Philippians 4:19). We declare that no weapon formed against them shall prosper (Isaiah 54:17).
In Jesus' name, we pray for their deliverance, healing, and spiritual growth. Guide them in Your truth and fill them with Your Holy Spirit.
Amen.
We encourage you to continue praying and reading the Bible, growing in your faith and knowledge of God. If the attacks continue, seek support from a local pastor or spiritual leader in your community. Always remember that our battle 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). Stand firm in your faith and in the power of Jesus' name.
