The Witness, the True Light, and the Word Made Flesh
John the Baptist is introduced as a witness, not the light itself, so attention remains fixed on the true Light who comes into the world. The tragedy and promise of the incarnation appear together: the world made through the Word fails to recognize him, yet those who receive him are given the right to become God’s children by a birth that comes from God. Verse 14 then uses dwelling/tabernacle language and divine glory to place Jesus inside the Exodus presence story. Grace and truth echo the revelation of God’s covenant character in Exodus 34, while verses 17–18 contrast Moses’ real gift of Torah with the climactic revelation of God through Jesus Christ.
