Jesus as the Immanuel revealed the way out of the darkness of this world into the light of the realm of God’s existence.
Jesus proclaimed to the multitudes, “I am the light of the world. He who follows Me will not walk in darkness, but will have the light of life” (Jn 8:12). These words were John’s quotation of what Jesus affirmed during His earthly ministry. But the Holy Spirit was not finished with this concept about who the Son of God was among us. Concerning His last revelation of Jesus as the light, the Holy Spirit inspired John to write, “But if we walk in the light as He is in the light, we have fellowship with one another” (1 Jn 1:7). “God is light and in Him is no darkness at all” (1 Jn 1:5). The light is where all of us want to be. We seek to escape from the darkness of this world in order to walk in the eternal light of God. It was for this reason that Jesus brought the eternal light of God into this world. We follow Him as the light, therefore, in order to be led out of darkness into the eternal realm of light in the presence of God.
For those Jews of faith in the first century, the Messiah was more than what they had hoped. Not long into Jesus’ ministry, many people of faith soon discovered that “in Him was life, and the life was the light of men” (Jn 1:4). Jesus had come into a world of darkness, but “the light shines in the darkness, and the darkness did not understand it” (Jn 1:5). Because God is light, anyone who would come from the presence of God must of necessity bring with Him light (1 Jn 1:5-7). And since Jesus came from God, He came as a bearer of light for all who live in the darkness of the world.
