What the Bible says about Jesus as the Light of Divine Salvation
(From Forerunner Commentary)
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.
