Actually, there is a specific instance in the Bible where the Apostles DID fail, though it was in the aspect of casting out of demons.
The one instance that comes to mind is in the Book of Mathew 17.
The disciples had a failure of strength of belief and while Jesus was able to cast out the demon they were unable to as their faith, at that time, didn’t compare even to a mustard seed.
Christ implored them to strengthen their faith and they never failed again.
Quite different from the charlatans of today fail over and over again.
The Benny Hinns of the world are midway carnies.
