142. What healings of the sick do the gospels relate?

The gospels relate that Jesus healed blind, lame, deaf, and leprous people. These healings point to the divine nature of Jesus Christ, who acted as God when He spoke to the people of Israel: “I am the Lord who heals you” (Exodus 15: 26). These miracles of healing were always closely linked to the faith of the affected individuals (cf. e.g. Luke 18: 35-43).
