Luke 5:13

And he stretched forth his hand and touched him, saying, I will; be thou made clean. And straightway the leprosy departed from him.

To touch a leper resulted in the ceremonial defilement of the one who touched; but Jesus did not hesitate to incur such defilement on behalf of those whom he came to deliver. In a similar way, he touched the bier of the dead (Luke 7:14). As often noted, Christ's cures were instantaneous, performed without physical effort on his part, and free of the type of incantations, ostentatious prayers, and hysterical behavior associated with so-called "healings" today. His were real, immediate, and designed to demonstrate his own heavenly power.
