“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. “The whole head is sick, and the whole heart faint. In some instances of healing, Jesus did not at once grant the blessing sought. But in the case of leprosy, no sooner was the appeal made than it was granted. When we pray for earthly blessings, the answer to our prayer may be delayed, or God may give us something other than we ask, but not so when we ask for deliverance from sin. It is His will to cleanse us from sin, to make us His children, and to enable us to live a holy life.”
