20:29-34 Spiritual Sight One of the most interesting phenomena in the Gospels is how well those who were physically blind could see spiritual truth. Having listened carefully to the testimonies of those who had seen Jesus, these two men were able to sort out the facts rather than be distracted. So they shouted “Lord, Son of David, have mercy on us!” (20:31). They recognized that Jesus was the promised Davidic Messiah, and that he could give them mercy and heal their physical blindness.
