He told them therefore that He was not a Teacher asking for a disciple who would parrot His sayings; He was a Saviour Who first disturbed a conscience and then purified it. But many would never get beyond hating the disturber. The Light is no boon, except to those who are men of good will; their lives may be evil, but at least they want to be good. His Presence, He said, was a threat to sensuality, avarice, and lust. When a man has lived in a dark cave for years, his eyes cannot stand the light of the sun; so the man who refuses to repent turns against mercy. No one can prevent the sun from shining, but every man can pull down the blinds and shut it out.
