John gets right down to business as he begins his account of Jesus: He is the Word; the Wisdom; the expression of the very essence of God; he is the agent of creation; the source of life; the light of the world that casts out darkness and brings us into his marvellous light. He is God. John is not using subtlety to begin his biography of Jesus. It can't be more straightforward than this: Jesus is the enthroned king of the universe, and he is worthy of our worship. He is worth following and surrendering our lives to.
