No Christian needs deliverance from the devil, the death of Jesus Christ has already set us free from every satanic bondage. “Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son" (Colossians 1:12-13). Today You can simply walk out from any demonic oppression and there is nothing Satan can do about it. Resist the devil, and he will flee from you (James 4:7). If death could not hold him in that grave, then nothing can hold me back. We are Unstoppable, Stronger than the strongman, 10 steps ahead of the devil, khayaaaaa....!
The Bible talks about Paul and Silas in Prison, physically confined but spiritual set free, whilst in Prison, the Bible says they began praying and singing hymns to God and as they did this, the bible says, there was a great earthquake, and the prison was shaken to its foundations and all the doors flew open, and the chains of every prisoner fell off (Acts 16:25-26). How could the prison doors remain closed for if the Son sets you free, you will be free indeed (John 8:36), how could the chains remain for where the spirit of the Lord is, there is liberty (2 Corinthians 3:17). They did not have to have the keys to open them doors, they did not have to have the keys to remove them chains on their hands, these things came out by themselves, thats what happens when we pray, doors open by themselves.
