And he said, Lord, I believe—the Kyrie means more than in John 9:36—and he worshipped him. The verb προσκυνεῖν is used by John for homage paid to God (John 4:20; John 12:20; and twenty-three times in the Revelation, always in the sense of "worship").
This prostration, when no prayer was offered, no forgiveness asked, but a simple act of faith exercised, was nothing less than the highest homage the man could pay. The adoration of this man is a fitting climax to the scene (John 8:59), and anticipates that of Thomas (John 20:28).
The higher significance of the Sonship dawned upon him in the unearthly tone and manner of the Lord. These scenes, and the offer of Divine homage unrebuked by Jesus and uncommented upon by the evangelist, are among the most potent arguments for the belief of the Church in the Divine nature of the Lord.
