“The work of Christ in cleansing the leper from his terrible disease is an illustration of His work in cleansing the soul from sin. The man who came to Jesus was ‘full of leprosy.’ Its deadly poison permeated his whole body. The disciples sought to prevent their Master from touching him; for he who touched a leper became himself unclean. But in laying His hand upon the leper, Jesus received no defilement. His touch imparted life-giving power. The leprosy was cleansed. Thus it is with the leprosy of sin,—deep-rooted, deadly, and impossible to be cleansed by human power.”—Ellen G. White, The Desire of Ages, p. 266.
