What an example of firm faith the blind man gives us! […] What power could the water possibly contain that when the blind man’s eyes were moistened with it they were cured? Surely some mysterious eye salve, or precious medicine made up in the laboratory of some wise alchemist, would have done better? But the man believed; he acted upon the command of God, and he returned with eyes full of light.” (St. Josemaria Escriva, Hom., 2, 193)
He was not sent to condemn the world but to save it (cf. 3:17); but his presence among us already constitutes a kind of judgment, for each of us has to take a stand, either to accept or reject him.
