How do we know that Jesus has authority over sickness?
Answered in 2 sources
Jesus' authority over sickness is demonstrated through His ability to heal with a single command, as illustrated by the centurion's faith.
The healing of the centurion's servant in Luke 7 establishes Jesus' authority over illness without needing physical contact or elaborate rituals. The centurion understood the nature of authority, likening it to his own command over soldiers, and recognized that Jesus held the same power over sickness. His faith led him to believe that a mere word from Christ could effect healing, which underscores the uniqueness of Jesus' authority as divine. This account teaches us that Jesus is not limited by space or circumstance; His spoken word commands the very forces of nature and illness, affirming His supernatural sovereignty.
