Is a Novena a healer, or is your healer Jesus? Out of all the healings recorded in the Bible done by Jesus, did He have any of them do a Novena before they were healed? Jesus spoke, and they were healed. Jesus is your healer too. God spoke the universe and everything in it into existence. He spoke, and it happened. Jesus spoke, and it happened. The apostles spoke, and healings happened. The clothes of Paul were imparted healing into them and when they touched a person the person was healed.
As believer here on earth you are to be the exact image of Jesus and what Jesus has done. He no longer is setting foot on this earth, but He set foot on this earth now through believers. He has given believers authority over all the power of the enemy. Epilepsy is a manifestation of the enemy, it is demonic and not from God. You speak to the epilepsy and tell it to go because it has no authority to be in your body. Jesus said to speak to the mountain and it would move if we believed.
In the name of Jesus, I bless you with the life of God.
