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 Grk “every man” (but in a generic sense, “every person,” or “every human being”).
6 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.
sn In v. 9 the world (κόσμος, kosmos) is mentioned for the first time. This is another important theme word for John. Generally, the world as a Johannine concept does not refer to the totality of creation (the universe), although there are exceptions at 11:9. 17:5, 24, 21:25, but to the world of human beings and human affairs. Even in 1:10 the world created through the Logos is a world capable of knowing (or reprehensibly not knowing) its Creator. Sometimes the world is further qualified as this world (ὁ κόσμος οὗτος, Jo kosmos Joutos) as in 8:23, 9:39, 11:9, 12:25, 31; 13:1, 16:11, 18:36. This is not merely equivalent to the rabbinic phrase “this present age” (ὁ αἰών οὗτος, Jo aiwn Joutos) and contrasted with “the world to come.” For John it is also contrasted to a world other than this one, already existing; this is the lower world, corresponding to which there is a world above (see especially 8:23, 18:36). Jesus appears not only as the Messiah by means of whom an eschatological future is anticipated (as in the synoptic gospels) but also as an envoy from the heavenly world to this world.
