As his gospel begins, the apostle John writes that Jesus Christ "came to His own, and His own did not receive Him" (John 1:11). That He "came to His own" describes the content of John 9, where we find Him healing a man born blind (John 9:1-38). Chapters 9-12 emphasize Jesus' calling out a people of His own in the midst of, and in spite of, growing hostility from Jewish authorities. As His own people are rejecting him, Christ begins to call out a new people, first exemplified by the story of His calling of the blind man.
This miracle, which John alone relates, occurs in a conspicuous setting. The sixth of eight miracles recorded in his gospel, it is an illustration of the previous day's significant affirmation of Jesus as "the Light of the world" (John 8:12). He is the Light of divine salvation that overcomes the darkness of man's moral and physical blindness. Thus, as the Light, He gave sight to a blind man.

The Miracles of Jesus Christ: Healing a Man Born Blind (Part One)
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.
