1 tn To this point the author has used past tenses (imperfects, aorists); now he switches to a present. The light continually shines (thus the translation, “shines on”). Even as the author writes, it is shining. The present here most likely has gnomic force (though it is possible to take it as a historical present); it expresses the timeless truth that the light of the world (cf. 8:12, 9:5, 12:46) never ceases to shine.
sn The light shines on. The question of whether John has in mind here the preincarnate Christ or the incarnate Christ is probably too specific. The incarnation is not really introduced until v. 9, but here the point is more general: It is of the very nature of light, that it shines.
2 sn The author now introduces what will become a major theme of John’s Gospel: the opposition of light and darkness. The antithesis is a natural one, widespread in antiquity. Gen 1 gives considerable emphasis to it in the account of the creation, and so do the writings of Qumran. It is the major theme of one of the most important extra-biblical documents found at Qumran, the so-called War Scroll, properly titled The War of the Sons of Light with the Sons of Darkness. Connections between John and Qumran are still an area of scholarly debate and a consensus has not yet emerged. See T. A. Hoffman, “1 John and the Qumran Scrolls,” BTB 8 (1978): 117-25.
3 tn Grk “and,” but the context clearly indicates a contrast, so this has been translated as an adversative use of καί (kai).
4 tn Or “comprehended it,” or “overcome it.” The verb κατέλαβεν (katelaben) is not easy to translate. “To seize” or “to grasp” is possible, but this also permits “to grasp with the mind” in the sense of “to comprehend” (esp. in the middle voice). This is probably another Johannine double meaning – one does not usually think of darkness as trying to “understand” light. For it to mean this, “darkness” must be understood as meaning “certain people,” or perhaps “humanity” at large, darkened in understanding. But in John’s usage, darkness is not normally used of people or a group of people. Rather it usually signifies the evil environment or ‘sphere’ in which people find themselves: “They loved darkness rather than light” (John 3:19). Those who follow Jesus do not walk in darkness (8:12). They are to walk while they have light, lest the darkness “overtake/overcome” them (12:35, same verb as here). For John, with his set of symbols and imagery, darkness is not something which seeks to “understand (comprehend)” the light, but represents the forces of evil which seek to “overcome (conquer)” it. The English verb “to master” may be used in both sorts of contexts, as “he mastered his lesson” and “he mastered his opponent.”
5 tn Or “Lord.” The Greek κύριος (kurios) means both “Sir” and “Lord.” In this passage it is not at all clear at this point that the crowd is acknowledging Jesus as Lord. More likely this is simply a form of polite address (“sir”).
6 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.
7 tn Grk “answered and said to him.”
8 sn Should Thomas’ exclamation be understood as two subjects with the rest of the sentence omitted (“My Lord and my God has truly risen from the dead”), as predicate nominatives (“You are my Lord and my God”), or as vocatives (“My Lord and my God!”)? Probably the most likely is something between the second and third alternatives. It seems that the second is slightly more likely here, because the context appears confessional. Thomas’ statement, while it may have been an exclamation, does in fact confess the faith which he had previously lacked, and Jesus responds to Thomas’ statement in the following verse as if it were a confession. With the proclamation by Thomas here, it is difficult to see how any more profound analysis of Jesus’ person could be given. It echoes 1:1 and 1:14 together: The Word was God, and the Word became flesh (Jesus of Nazareth). The Fourth Gospel opened with many other titles for Jesus: the Lamb of God (1:29, 36); the Son of God (1:34, 49); Rabbi (1:38); Messiah (1:41); the King of Israel (1:49); the Son of Man (1:51). Now the climax is reached with the proclamation by Thomas, “My Lord and my God,” and the reader has come full circle from 1:1, where the author had introduced him to who Jesus was, to 20:28, where the last of the disciples has come to the full realization of who Jesus was. What Jesus had predicted in John 8:28 had come to pass: “When you lift up the Son of Man, then you will know that I am he” (Grk “I am”). By being lifted up in crucifixion (which led in turn to his death, resurrection, and exaltation with the Father) Jesus has revealed his true identity as both Lord (κύριος [kurios], used by the LXX to translate Yahweh) and God (θεός [qeos], used by the LXX to translate Elohim).
9 tn Grk “saw this one.”
