² sn This is eternal life. The author here defines eternal life for the readers, although it is worked into the prayer in such a way that many interpreters do not regard it as another of the author’s parenthetical comments. It is not just unending life in the sense of prolonged duration. Rather it is a quality of life, with its quality derived from a relationship with God. Having eternal life is here defined as being in relationship with the Father, the one true God, and Jesus Christ whom the Father sent. Christ (Χριστός, Christos) is not characteristically attached to Jesus’ name in John’s Gospel; it occurs elsewhere primarily as a title and is used with Jesus’ name only in 1:17. But that is connected to its use here: The statement here in 17:3 enables us to correlate the statement made in 1:18 of the prologue, that Jesus has fully revealed what God is like, with Jesus’ statement in 10:10 that he has come that people might have life, and have it abundantly. These two purposes are really one, according to 17:3, because (abundant) eternal life is defined as knowing (being in relationship with) the Father and the Son. The only way to gain this eternal life, that is, to obtain this knowledge of the Father, is through the Son (cf. 14:6). Although some have pointed to the use of know (γινώσκω, ginōskō) here as evidence of Gnostic influence in the Fourth Gospel, there is a crucial difference: For John this knowledge is not intellectual, but relational. It involves being in relationship.

¹ sn Now the reference to the commandments (plural) in 15:10 have been reduced to a singular commandment: The disciples are to love one another, just as Jesus has loved them. This is the “new commandment” of John 13:34, and it is repeated in 15:17. The disciples’ love for one another is compared to Jesus’ love for them. How has Jesus shown his love for the disciples? This was illustrated in 13:1-20 in the washing of the disciples’ feet, introduced by the statement in 13:1 that Jesus loved them “to the end.” In context this constitutes a reference to Jesus’ self-sacrificial death on the cross on their behalf; the love they are to have for one another is so great that it must include a self-sacrificial willingness to die for one another if necessary. This is exactly what Jesus is discussing here because he introduces the theme of his sacrificial death in the following verse. In John 10:18 and 14:31 Jesus spoke of his death on the cross as a commandment he had received from his Father, which also links the idea of commandment and love as they are linked here. One final note: It is not just the degree or intensity of the disciples’ love for one another that Jesus is referring to when he introduces by comparison his own death on the cross (that they must love one another enough to die for one another) but the very means of expressing that love: It is to express itself in self-sacrifice for one another, sacrifice up to the point of death, which is what Jesus himself did on the cross (cf. 1 John 3:16).

² 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.

² sn The verb ascended is a perfect tense in Greek (ἀναβέβηκεν, anabebēken) which seems to look at a past, completed event. (This is not as much of a problem for those who take Jesus’ words to end at v. 12, and these words to be a comment by the author, looking back on Jesus’ ascension.) As a saying of Jesus, these words are a bit harder to explain. Note, however, the lexical similarities with 1:51: “ascending,” “descending,” and “son of man.” Here, though, the ascent and descent is accomplished by the Son himself, not the angels as in 1:51. There is no need to limit this saying to Jesus’ ascent following the resurrection, however; the point of the Jacob story (Gen 28), which seems to be the background for 1:51, is the freedom of communication and relationship between God and men (a major theme of John’s Gospel). This communication comes through the angels in Gen 28 (and John 1:51), but here (most appropriately) it comes directly through the Son of Man. Although Jesus could be referring to a prior ascent, after an appearance as the preincarnate Son of Man, more likely he is simply pointing out that no one from earth has ever gone up to heaven and come down again. The Son, who has come down from heaven, is the only one who has been ‘up’ there. In both Jewish intertestamental literature and later rabbinic accounts, Moses is portrayed as ascending to heaven to receive the Torah and descending to distribute it to men (e.g., Targum Ps 68:19.) In contrast to these Jewish legends, the Son is the only one who has ever made the ascent and descent.

¹ sn Verse 12 is merely a transitional note in the narrative (although Capernaum does not lie on the direct route to Jerusalem from Cana). Nothing is mentioned in John’s Gospel at this point about anything Jesus said or did there (although later his teaching is mentioned, see 6:59). From the synoptics it is clear that Capernaum was a center of Jesus’ Galilean ministry and might even be called “his own town” (Matt 9:1). The royal official whose son Jesus healed (John 4:46-54) was from Capernaum. He may have heard Jesus speak there, or picked up the story about the miracle at Cana from one of Jesus’ disciples. The town of Capernaum itself was located on the northwest shore of the Sea of Galilee, 680 ft (204 m) below sea level. It existed since Hasmonean times and was a major trade and economic center in the North Galilean region. The population in the first century is estimated to be around 1,500. In modern times the site was discovered in 1838 by the American explorer E. Robinson, and major excavations began in 1905 by German archaeologists H. Kohl and C. Watzinger. Not until 1968, however, were remains from the time of Jesus visible; in that year V. Corbo and S. Loffreda began a series of annual archaeological campaigns that lasted until 1985. This work uncovered what is thought to be the house of Simon Peter as well as ruins of the first century synagogue beneath the later synagogue from the fourth or fifth century A.D. Today gently rolling hills and date palms frame the first century site, a favorite tourist destination of visitors to the Galilee.

¹ tc Most mss (א M) read “amen” (ἀμήν, amēn) after “all” (πάντων, pantōn). It is, however, not found in other significant mss (A 1006 1841). It is easier to account for its addition than its omission from the text if original. Such a conclusion is routinely added by scribes to NT books because a few of these books originally had such an ending (cf. Rom 16:27; Gal 6:18; Jude 25). A majority of Greek witnesses have the concluding ἀμήν in every NT book except Acts, James, and 3 John (and even in these books, ἀμήν is found in some witnesses). It is thus a predictable variant.

⁴ sn It is possible that the designation friends (φίλοι, philoi) indicates that these are personal friends of Gaius who send their greetings, but if this is the case it is somewhat surprising that their names are not mentioned, especially when the author instructs Gaius, Greet the friends there by name. More likely this is an alternative to “brothers” (ἀδελφοί, adelphoi) as an early Christian self-designation, especially within the Johannine community. It may have arisen in the Johannine community from Jesus’ teaching in John 15:13-15, “you are my friends if you do what I command you.”

² sn Which church does the author refer to here? The church where Gaius is, the church where the author is, a different local church where the “brothers” are, or the ‘universal’ church, the church at large? Since the suggestion in 3 John 3 is that the “brothers” have come and testified in the author’s church about what Gaius has done for them, it seems most likely that the “church” mentioned here is also the author’s church, where he is currently located. Other possibilities cannot be ruled out, but seem unnecessarily complicated.

¹ tn The meaning of ἀδικία (adikia) here is “unrighteousness” (BDAG 20 s.v. 2). It refers to the opposite of that which is δίκαιος (dikaios, “right, just, righteous”) which is used by the author to describe both God and Jesus Christ (1 John 1:9; 2:2, 29). Here, having implied that sins committed by believers (sins “not to death”) may be prayed for and forgiven, the author does not want to leave the impression that such sin is insignificant because this could be viewed as a concession to the views of the opponents (who as moral indifferentists have downplayed the significance of sin in the Christian’s life).

⁷ tn The standard English translation for ἡ νίκη (hē nikē) is “victory” (BDAG 673 s.v.) but this does not preserve the relationship with the cognate verb νικάω (nikaō; used in 2:13, 14 and present in this context in participial form in 5:4b and 5:5). One alternative would be “conquest,” although R. E. Brown (Epistles of John [AB], 570) suggests “conquering power” as a translation for ἡ νίκη since here it is a metonymy for the means of victory or the power that gives victory, referring to believers’ faith.

¹ tn The first ὅτι (hoti) clause, following a verb of perception, introduces an indirect discourse clause giving the content of what the readers are assumed to know: that they have passed over from death to life, that is, that they possess eternal life. The author gives a similar reassurance to his readers in 5:13. Alternation between the verbs οἶδα (oida) and γινώσκω (ginōskō) in 1 John is probably a matter of stylistic variation (of which the writer is extremely fond) rather than indicative of a subtle difference in meaning.

² tn The problem of the present tense of ποιεῖ (poiei) here is exactly that of the present tense of ἁμαρτάνει (hamartanei) in 3:6. Here in 3:9 the distinction is sharply drawn between “the one who practices sin” in 3:8, who is of the devil, and “the one who is fathered by God” in 3:9, who “does not practice sin.” See S. Kubo (“I John 3:9: Absolute or Habitual?” AUSS 7 [1969]: 47-56) for a fuller discussion of the author’s argument as based on a sharp antithesis between the recipients (true Christians) and the opponents (heretics).

² tn The interpretive problem raised by the use of the present tense ἁμαρτάνει (hamartanei) in this verse (and ποιεῖ [poiei] in 3:9 as well) is that (a) it appears to teach a sinless state of perfection for the true Christian, and (b) it appears to contradict the author’s own statements in 2:1-2 where he acknowledged that Christians do indeed sin. (1) One widely used method of reconciling the acknowledgment in 2:1-2 that Christians do sin with the statements in 3:6 and 3:9 that they do not is expressed by M. Zerwick (Biblical Greek §251). He understands the aorist to mean “commit sin in the concrete, commit some sin or other” while the present means “be a sinner, as a characteristic «state».” N. Turner (Grammatical Insights, 151) argues essentially the same as Zerwick, stating that the present tense ἁμαρτάνει is stative (be a sinner) while the aorist is ingressive (begin to be a sinner, as the initial step of committing this or that sin). Similar interpretations can be found in a number of grammatical works and commentaries. (2) Others, however, have questioned the view that the distinction in tenses alone can convey a “habitual” meaning without further contextual clarification, including C. H. Dodd (The Johannine Epistles [MNTC], 79) and Z. C. Hodges (“1 John,” BKCNT, 894). B. Fanning (Verbal Aspect [OTM], 215-17) has concluded that the habitual meaning for the present tense cannot be ruled out because there are clear instances of habitual presents in the NT where other clarifying words are not present and the habitual sense is derived from the context alone. This means that from a grammatical standpoint alone, the habitual present cannot be ruled out in 1 John 3:6 and 9. It is still true, however, that it would have been much clearer if the author had reinforced the habitual sense with clarifying words or phrases in 1 John 3:6 and 9 if that is what he had intended. Dodd’s point, that reliance on the distinction in tenses alone is quite a subtle way of communicating such a vital point in the author’s argument, is still valid. It may also be added that the author of 1 John has demonstrated a propensity for alternating between present and aorist tenses for purely stylistic reasons (see 2:12).

⁴ tn In this context ἐάν (ean) does not indicate (1) uncertainty about whether or not what believers will be shall be revealed, but rather (2) uncertainty about the exact time the event will take place. In the Koine period ἐάν can mean “when” or “whenever” and is virtually the equivalent of ὅταν (hotan; see BDAG 268 s.v. ἐάν 2). It has this meaning in John 12:32 and 14:3. Thus the phrase here should be translated, “we know that whenever it is revealed.”

¹ tn The mood of γινώσκετε (ginōskete) may be understood as (1) indicative or (2) imperative. It is better to understand the verb here as indicative because in 1 John “knowledge” is something one has as a result of being a believer (2:3, 5, 20, 21; 3:16, 19, 24; 4:2, 13; 5:2) rather than something one has to be exhorted about. The change in verbs from οἶδα (oida) to γινώσκω (ginōskō) is another example of Johannine stylistic variation.

¹ sn The one who hates his fellow Christian. The author’s paradigm for the opponents portrays them as those who show hatred for fellow Christians (Grk “brothers,” but not referring to one’s physical siblings). This charge will be much more fully developed in chap. 3, where the author will compare the opponents to Cain (who is the model for one who hates a brother, since he ultimately murdered his own brother). In 1 John 3:17 the specific charge against the opponents will be failing to give material aid to a brother in need.

⁴ tn Grk “that one.” Context indicates a reference to Jesus here. It is clear that ἐκεῖνος (ekeinos) here does not refer to the same person as αὐτῷ (autō) in 2:6a. The switch to ἐκεῖνος indicates a change in the referent, and a reference to Jesus Christ is confirmed by the verb περιεπάτησεν (periepatēsen), an activity which can only describe Jesus’ earthly life and ministry, the significance of which is one of the points of contention the author has with the opponents. In fact, ἐκεῖνος occurs 6 times in 1 John (2:6; 3:3, 5, 7, 16; and 4:17), and each one refers to Jesus Christ.

¹ sn The final virtue or character quality in this list is “love” (ἀγάπη, agapē). The word was not used exclusively of Christian or unselfish love in the NT (e.g., the cognate, ἀγαπάω [agapaō], is used in John 3:19 of the love of darkness), but in a list such as this in which ἀγάπη is obviously the crescendo, unselfish love is evidently in view. R. Bauckham (Jude, 2 Peter [WBC], 187) notes that as the crowning virtue, ἀγάπη encompasses all the previous virtues.

³ tn The word “it” is not in the Greek text but is implied. Direct objects were often omitted in Greek when clear from the context. The use of “it” here as direct object of the verb πιστεύσω (pisteusō) specifies exactly what Thomas was refusing to believe: that Jesus had risen from the dead, as reported by his fellow disciples. Otherwise the English reader may be left with the impression Thomas was refusing to “believe in” Jesus, or “believe Jesus to be the Christ.” The dramatic tension in this narrative is heightened when Thomas, on seeing for himself the risen Christ, believes more than just the resurrection (see John 20:28).

¹ sn The term day of preparation (παρασκευή, paraskeuē) appears in all the gospels as a description of the day on which Jesus died. It could refer to any Friday as the day of preparation for the Sabbath (Saturday), and this is the way the synoptic gospels use the term (Matt 27:62, Mark 15:42, and Luke 23:54). John, however, specifies in addition that this was not only the day of preparation of the Sabbath, but also the day of preparation of the Passover, so that the Sabbath on the following day was the Passover (cf. 19:31).
