Mark 5:15

And they come to Jesus, and behold him that was possessed with demons sitting, clothed and in his right mind, even him that had the legion: and they were afraid.

This contrasts with the picture Mark gave of the man before the demons were cast out. What a tragic picture he presented: naked, bleeding, furtive, dwelling in tombs, constantly crying out, etc. Behold the change. He is clothed and in his right mind, sitting at the feet of Jesus! This shows what Christianity does. "It clothes the naked, moderates the madness of passion, and many a man with a ragged coat and an empty pocket before conversion now has a purse and two coats."[8]

And they were afraid ... Such a powerful demonstration of God's power instilled fear in a whole community.
