God has always been a healer. It is His heart to heal. In Exodus 15:26, He revealed one of His names to Israel: Jehovah-Raphah: I am the LORD who heals you. David speaks of him in Psalm 103:3 as the God “who forgives all your iniquities; who heals all your diseases.”
Jesus, in His life on earth as the God-man, fully demonstrated God as Healer. We are told that “Jesus went about … healing all manner of sickness and all manner of disease among the people” (Matthew 4:23). Matthew 12:15 informs us that “great multitudes followed him, and he healed them all.”
But He went further, in providing for people in the ages to come to be healed through His atonement at the cross and in His scourging before the cross. Isaiah 53:5 prophesies, ” But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.” He gave all of His followers who would come after Him the authority to heal in His Name: “And these signs shall follow them who believe: In my name they shall cast out devils; … they shall lay hands on the sick, and they shall recover” (Mark 16:17, 18).
There are misguided people who teach that God no longer heals today. However, the Bible reveals God as Healer by His very nature, and when something is His nature, it does not cease to be manifested, but continues onward. Psalm 103:3 and Isaiah 53:5 both link together God’s forgiveness of our sins and His healing of our bodies — “who forgives all your iniquities; who heals all your diseases” and “wounded for our transgressions … with his stripes we are healed.” If we reason that He no longer heals, logically we would have to reason that He no longer forgives either. Thank God that He still does both, and He does them to the fullest.
