Bible verses about Healing as a Work of God
(From Forerunner Commentary)
The miracle of healing displays Jesus Christ giving sight to the blind. Healing is a work of the God of the Old Testament, as seen in Psalm 146:8, "The LORD opens the eyes of the blind . . ." (see also Exodus 4:10-12). Giving sight to the blind is also a work of the Messiah, as prophesied in Isaiah 35:4-5, "He will come and save you. Then the eyes of the blind shall be opened. . . ." Jesus' healing of the man born blind, then, is another testimony of His Deity and of the fact that He is the Messiah.
In spite of this great testimony, most of the witnesses missed the miracle's message, and the religious leaders persecuted the newly healed man. Moreover, they condemned the Healer, Jesus Christ, calling Him a sinner. Greater blindness existed in their lives than in the man Christ healed; he was only physically blind but their blindness was spiritual, of the heart and mind.
