Expositor's Bible Commentary Commentary John 9:37

"Jesus said unto him, Thou hast both seen him, and he it is that speaketh with thee." — John 9:37 (ASV)

When Jesus said that the “Son of Man” was the person speaking, the man instantly responded by worshiping Jesus. He was ready to believe on the one who had healed him. The progress in his spiritual understanding of Christ is marked by progressive descriptions: “The man they call Jesus” (v.11); “he is a prophet” (v.17); “from God” (v.33); “Son of Man” (v.35); and, lastly, “Lord” (v.38). This progression illustrates the man’s movement from darkness to light, both physically and spiritually.
