Healings are very much a part of the Holy Bible and the Gospels.
The Jews fasted quite frequently in the OT for healings one case was in the Book of Samuel where he was healed of a physical sickness after 3 days, Healings are all through-out the Bible.
I am aware of the accounts of healing in the Bible, and believe them. But there is no reason to believe that Benny Hinn can actually heal anyone.
