“Lord, if you wish, you can make me clean.”

He stretched out his hand, touched him, and said, “I will do it. Be made clean.”

-- Mt 8:1-4

Often Jesus asks the sick to believe. He makes use of signs to heal: spittle and the laying on of hands, mud and washing. The sick try to touch him, "for power came forth from him and healed them all." And so in the sacraments Christ continues to "touch" us in order to heal us.

-- CCC 1504
