How do we know Jesus has the authority to heal us?

The authority of Jesus as the great physician is established in His identity as the sovereign Lord of all. In 1 Timothy 6:15, He is described as the king of kings and Lord of lords. His ability to heal is confirmed through numerous miracles, as recounted in the Gospels, such as restoring sight to the blind and curing the sick (Luke 7:21). This authority culminates in His ability to forgive sins, which He demonstrated when He said to the man sick of the palsy, 'Thy sins be forgiven thee' (Matthew 9:2). This forgiveness highlights the deeper work of healing He performs, addressing the spiritual condition of all humanity.
