John 5:3-4 KJV
 In these lay a great multitude of impotent folk, of blind, halt, withered, waiting for the moving of the water.  For an angel went down at a certain season into the pool, and troubled the water: whosoever then first after the troubling of the water stepped in was made whole of whatsoever disease he had.
My first question for you is–do you believe there was an angel who came down at a certain season into the pool, and troubled the waters?
So one person each time could be healed?
But no crazier than believing that Jesus healed the man who had been at the pool so long, who does not turn out to be the most grateful healed man.
I have skirted the issue of the angel at the pool for years, choosing instead to focus on Jesus and the man and the religious oligarchs who made it hard for Jesus.
I understand that angel complicates everything–messenger of God who brings some healing, brings some hope only
In a certain season.
