8:12 Then Jesus spoke out again, 8 “I am the light of the world. 9 The one who follows me will never 10 walk in darkness, but will have the light of life.”
1 tn Or “to bear witness.”
2 tn The idiom “sons of light” means essentially “people characterized by light,” that is, “people of God.”
3 tn John uses ζωή (zwh) 37 times: 17 times it occurs with αἰώνιος (aiwnios), and in the remaining occurrences outside the prologue it is clear from context that “eternal” life is meant. The two uses in 1:4, if they do not refer to “eternal” life, would be the only exceptions. (Also 1 John uses ζωή 13 times, always of “eternal” life.)
4 tn Or “humanity”; Grk “of men” (but ἄνθρωπος [anqrwpo"] is used in a generic sense here, not restricted to males only, thus “mankind,” “humanity”).
4 sn Jesus’ statement I am the light of the world connects the present account with 8:12. Here (seen more clearly than at 8:12) it is obvious what the author sees as the significance of Jesus’ statement. “Light” is not a metaphysical definition of the person of Jesus but a description of his effect on the world, forcing everyone in the world to ‘choose up sides’ for or against him (cf. 3:19-21).
5 tn Or “this is the reason for God judging,” or “this is how judgment works.”
6 tn Grk “and men,” but in a generic sense, referring to people of both genders (as “everyone” in v. 20 makes clear).
6 tn Grk “Then again Jesus spoke to them saying.”
7 sn The theory proposed by F. J. A. Hort (The New Testament in the Original Greek, vol. 2, Introduction; Appendix, 87-88), that the backdrop of 8:12 is the lighting of the candelabra in the court of women, may offer a plausible setting to the proclamation by Jesus that he is the light of the world. The last time that Jesus spoke in the narrative (assuming 7:53-8:11 is not part of the original text, as the textual evidence suggests) is in 7:38, where he was speaking to a crowd of pilgrims in the temple area. This is where he is found in the present verse, and he may be addressing the crowd again. Jesus’ remark has to be seen in view of both the prologue (John 1:4, 5) and the end of the discourse with Nicodemus (John 3:19-21). The coming of Jesus into the world provokes judgment: A choosing up of sides becomes necessary. The one who comes to the light, that is, who follows Jesus, will not walk in the darkness. The one who refuses to come, will walk in the darkness. In this contrast, there are only two alternatives. So it is with a person’s decision about Jesus. Furthermore, this serves as in implicit indictment of Jesus’ opponents, who still walk in the darkness, because they refuse to come to him. This sets up the contrast in chap. 9 between the man born blind, who receives both physical and spiritual sight, and the Pharisees (John 9:13, 15, 16) who have physical sight but remain in spiritual darkness.
8 tn The double negative οὐ μή (ou mh) is emphatic in 1st century Hellenistic Greek.
7 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.
8 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.
9 tn Grk “and,” but the context clearly indicates a contrast, so this has been translated as an adversative use of καί (kai).
10 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.”
8 tn Grk “came for a testimony.”
9 tn Or “to bear witness.”
10 tn Grk “all.”
9 tn Grk “every man” (but in a generic sense, “every person,” or “every human being”).
10 tn Or “He was the true light, who gives light to everyone who comes into the world.” The participle ἐρχόμενον (ercomenon) may be either (1) neuter nominative, agreeing with τὸ φῶς (to fw"), or (2) masculine accusative, agreeing with ἄνθρωπον (anqrwpon). Option (1) results in a periphrastic imperfect with ἦν (hn), ἦν τὸ φῶς… ἐρχόμενον, referring to the incarnation. Option (2) would have the participle modifying ἄνθρωπον and referring to the true light as enlightening “every man who comes into the world.” Option (2) has some rabbinic parallels: The phrase “all who come into the world” is a fairly common expression for “every man” (cf. Leviticus Rabbah 31.6). But (1) must be preferred here, because: (a) In the next verse the light is in the world; it is logical for v. 9 to speak of its entering the world; (b) in other passages Jesus is described as “coming into the world” (6:14, 9:39, 11:27, 16:28) and in 12:46 Jesus says: ἐγὼ φῶς εἰς τὸν κόσμον ἐλήλυθα (egw fw" ei" ton kosmon elhluqa); (c) use of a periphrastic participle with the imperfect tense is typical Johannine style: 1:28, 2:6, 3:23, 10:40, 11:1, 13:23, 18:18 and 25. In every one of these except 13:23 the finite verb is first and separated by one or more intervening words from the participle.
10 tn Grk “in the night.”
11 tn Or “he trips.”
11 sn John 3:16-21 provides an introduction to the (so-called) “realized” eschatology of the Fourth Gospel: Judgment has come; eternal life may be possessed now, in the present life, as well as in the future. The terminology “realized eschatology” was originally coined by E. Haenchen and used by J. Jeremias in discussion with C. H. Dodd, but is now characteristically used to describe Dodd’s own formulation. See L. Goppelt, Theology of the New Testament, 1:54, note 10, and R. E. Brown (John [AB], 1:cxvii-cxviii) for further discussion. Especially important to note is the element of choice portrayed in John’s Gospel. If there is a twofold reaction to Jesus in John’s Gospel, it should be emphasized that that reaction is very much dependent on a person’s choice, a choice that is influenced by his way of life, whether his deeds are wicked or are done in God (John 3:20-21). For John there is virtually no trace of determinism at the surface. Only when one looks beneath the surface does one find statements like “no one can come to me, unless the Father who sent me draws him” (John 6:44).
12 sn He was a lamp that was burning and shining. Sir 48:1 states that the word of Elijah was “a flame like a torch.” Because of the connection of John the Baptist with Elijah (see John 1:21 and the note on John’s reply, “I am not”), it was natural for Jesus to apply this description to John.
13 tn Grk “for an hour.”
13 tn Grk “Then Jesus said to them.”
14 tn Grk “Yet a little while the light is with you.”
15 sn The warning Walk while you have the light, so that the darkness may not overtake you operates on at least two different levels: (1) To the Jewish people in Jerusalem to whom Jesus spoke, the warning was a reminder that there was only a little time left for them to accept him as their Messiah. (2) To those later individuals to whom the Fourth Gospel was written, and to every person since, the words of Jesus are also a warning: There is a finite, limited time in which each individual has opportunity to respond to the Light of the world (i.e., Jesus); after that comes darkness. One’s response to the Light decisively determines one’s judgment for eternity.
14 tn Grk “Jesus answered.”
15 tn Or “he does not trip.”
16 sn What is the light of this world? On one level, of course, it refers to the sun, but the reader of John’s Gospel would recall 8:12 and understand Jesus’ symbolic reference to himself as the light of the world. There is only a limited time left (Are there not twelve hours in a day?) until the Light will be withdrawn (until Jesus returns to the Father) and the one who walks around in the dark will trip and fall (compare the departure of Judas by night in 13:30).
