How do we know that Jesus has authority to heal?

Jesus' authority to heal is evident in the miracle recorded in Matthew 8:5-13, where the centurion recognized His power to heal without even being physically present. The centurion understood authority; he was a man under authority and saw that Jesus had authority over illness and disease. When Christ declared, ‘I will come and heal him,’ it was not merely a statement, but an assertion of His divine prerogative. This demonstrates that Jesus is not only a healer but also the sovereign Lord who commands creation, confirming His ability to redeem and restore through His authority over all things.
