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.
