The Light of the World

Jim ButlerJohn 8:12–20

In John 8:12, Jesus declares 'I am the light of the world,' a claim that situates him within the great 'I Am' tradition of Exodus 3:14 and the Isaianic servant songs, asserting both his full deity as the eternal Son and the universal scope of his messianic mission to Jew and Gentile alike. The sermon traces the 'I Am' statements across John's Gospel, showing that Jesus consciously identifies himself with Yahweh and that the light-imagery of the Old Testament finds its fulfillment in his person and work. Darkness in John is not physical but ethical — the guilt, depravity, and rebellion of a world that hates the light — and the follower of Christ, by grace through faith, passes from that darkness into the light of life. The church is therefore called to hold forth the word of the gospel as light in a morally darkened age, trusting that God is able to transfer sinners from the kingdom of darkness into the kingdom of his Son.
