¹ tn The phrase “but if you do not believe me” contains an ellipsis; the Greek text reads Grk “but if not.” The ellipsis has been filled out (“but if [you do] not [believe me]…”) for the benefit of the modern English reader.

² tn Grk “because of the works.”

sn In the context of a proof or basis for belief, Jesus is referring to the miraculous deeds (signs) he has performed in the presence of the disciples.

³ sn Assuming the authenticity of John 9:38-39a (see the tc note following the bracket in v. 39), the man’s response after Jesus’ statement of v. 37 is extremely significant: He worshiped Jesus. In the Johannine context the word would connote its full sense: This was something due God alone. Note also that Jesus did not prevent the man from doing this. The verb προσκυνέω (proskunew) is used in John 4:20-25 of worshiping God, and again with the same sense in 12:20. This would be the only place in John’s Gospel where anyone is said to have worshiped Jesus using this term. As such, it forms the climax of the story of the man born blind, but the uniqueness of the concept of worshiping Jesus at this point in John's narrative (which reaches its ultimate climax in the confession of Thomas in John 20:28) may suggest it is too early for such a response and it represents a later scribal addition.

⁴ tn Or “that.” It is very difficult to determine whether ὅτι (Joti; 3 times in 16:9, 10, 11) should be understood as causal or appositional/explanatory: Brown and Bultmann favor appositional or explanatory, while Barrett and Morris prefer a causal sense. A causal idea is preferable here, since it also fits the parallel statements in vv. 10-11 better than an appositional or explanatory use would. In this case Jesus is stating in each instance the reason why the world is proven guilty or wrong by the Spirit-Paraclete.

⁵ sn Here (v. 9) the world is proven guilty concerning sin, and the reason given is their refusal to believe in Jesus. In 3:19 the effect of Jesus coming into the world as the Light of the world was to provoke judgment, by forcing people to choose up sides for or against him, and they chose darkness rather than light. In 12:37, at the very end of Jesus’ public ministry in John’s Gospel, people were still refusing to believe in him.
