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.

² tn Grk “killed to death,” an expression emphatic in its redundancy. The phrase behind this translation is ὡς ἐσφαγμένον (hōs esphagmenon). The particle ὡς is used in Greek generally for comparison, and in Revelation it is used often to describe the appearance of what the author saw. In this instance, the appearance of the beast’s head did not match reality because the next phrase shows that in fact it did not die. This text does not affirm that the beast died and was resurrected, but some draw this conclusion because of the only other use of the phrase, which refers to Jesus in 5:6.

³ tn Or “slaughtered”; traditionally, “slain.” The phrase behind this translation is ὡς ἐσφαγμένον (hōs esphagmenon). The particle ὡς is used in Greek generally for comparison, and in Revelation it is used often to describe the appearance of what the author saw. This phrase does not imply that the Lamb “appeared to have been killed” but in reality was not because the wider context of the NT shows that in fact the Lamb, i.e., Jesus, was killed. See 13:3 for the only other occurrence of this phrase in the NT.

³ sn The expression This is the solemn pronouncement of reflects an OT idiom. The LXX has the same Greek phrase (τάδε λέγει, tade legei) about 350 times, with nearly 320 of them having “the Lord” (Heb יהוה, Yahweh) as subject. That the author of Revelation would use such an expression seven times with the risen Christ as the speaker may well imply something of Christ’s sovereignty and deity. Cf. also Acts 21:11 in which the Holy Spirit is the speaker of this expression.

² tn Grk “dreaming.” The participle ἐνυπνιαζόμενοι (enupniazomenoi, “dreaming”) is adverbial to the pronoun οὗτοι (houtoi, “these”), though the particular relationship is not clear. It could mean, “while dreaming,” “by dreaming,” or “because of dreaming.” This translation has adopted the last option as Jude’s meaning, partially for syntactical reasons (the causal participle usually precedes the main verb) and partially for contextual reasons (these false teachers must derive their authority from some source, and the dreams provide the most obvious base). The participle ἐνυπνιαζόμενοι was sometimes used of apocalyptic visions, both of true and false prophets. This seems to be the meaning here.

⁷ sn The Greek term for Master (δεσπότης, despotēs) is the same term the author of 2 Peter used (2 Pet 2:1) to describe his Lord when he prophesied about these false teachers. Since δεσπότης is used only ten times in the NT, the verbal connection between these two books at this juncture is striking. This is especially so since both Peter and Jude speak of these false teachers as denying the Master (both using the same verb). The basic difference is that Peter is looking to the future, while Jude is arguing that these false teachers are here now.

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.”

¹ sn The exhortation do not imitate what is bad but what is good is clearly a reference to Diotrephes’ evil behavior. The author exhorts Gaius (whom he wishes to continue assisting the missionaries) not to follow the negative example of Diotrephes, but to do what is right. Implicitly there may be a contrast between the bad behavior of Diotrephes and the good reputation of Demetrius (mentioned in the following verse), but it seems more likely that Demetrius is himself one of the traveling missionaries (perhaps their leader), rather than the leader of a local congregation who, unlike Diotrephes, has supported the missionaries himself.

¹ sn Just as it is well with your soul. The equivalent contemporary idiom would be to speak of “spiritual” health as opposed to physical health. The author affirms that Gaius is indeed well off spiritually, and he prays that Gaius’ physical health would match his spiritual health, i.e., that Gaius would be as well off physically as he is spiritually. It is the spiritual health which is to be the standard by which one’s physical health is measured, not the other way round.

⁴ tn This is the same confession as in 1 John 4:2 except the perfect participle used there is replaced by a present participle (ἐρχόμενον, erchomenon) here. It is not clear why the author changed from a perfect participle in 1 John 4:2 to a present participle here. The perfect participle suggests a reference to the incarnation (past). The present participle could suggest a reference to the (future) second advent, but based on the similarity to 1 John 4:2 it is probably best to take it as referring to the incarnation.

¹ tn For the third time in 5:9-14 the author uses the construction αὕτη ἐστίν (hautē estin; 5:9, 11, 14). As in the previous instance (5:11) the ὅτι (hoti) clause which follows is epexegetical (explanatory) to the pronoun αὕτη and explains what the “confidence” (παρρησία, parrēsia) consists of (technically the subject is ἡ παρρησία, the predicate nominative is the pronoun αὕτη, and the ὅτι clause explains the predicate nominative): “And the confidence which we have before him is this, namely, that if we ask anything according to his will he hears us.”

¹ tn The ἵνα (hina) clause in 4:21 could be giving (1) the purpose or (2) the result of the commandment mentioned in the first half of the verse, but if it does, the author nowhere specifies what the commandment consists of. It makes better sense to understand this ἵνα clause as (3) epexegetical to the pronoun ταύτην (tautēn) at the beginning of 4:21 and thus explaining what the commandment consists of: “that the one who loves God should love his brother also.”

¹ tn The author proclaims in 4:8 ὁ θεὸς ἀγάπη ἐστίν (ho theos agapē estin), but from a grammatical standpoint this is not a proposition in which subject and predicate nominative are interchangeable (“God is love” does not equal “love is God”). The predicate noun is anarthrous, as it is in two other Johannine formulas describing God, “God is light” in 1 John 1:5 and “God is Spirit” in John 4:24. The anarthrous predicate suggests a qualitative force, not a mere abstraction, so that a quality of God’s character is what is described here.

³ sn As explained at 2:2, inherent in the meaning of the word translated atoning sacrifice (ἱλασμός, hilasmos) is the idea of turning away the divine wrath, so that “propitiation” is the closest English equivalent. God’s love for us is expressed in his sending his Son to be the propitiation (the propitiatory sacrifice) for our sins on the cross. This is an indirect way for the author to allude to one of the main points of his controversy with the opponents: the significance for believers’ salvation of Jesus’ earthly life and ministry, including especially his sacrificial death on the cross. The contemporary English “atoning sacrifice” communicates this idea more effectively.

¹ sn 1 John 4:1-6. These verses form one of three units within 1 John that almost all interpreters consider a single unit and do not divide up (the other two are 2:12-14 and 15-17). The subject matter is so clearly different from the surrounding context that these clearly constitute separate units of thought. Since the Holy Spirit is not the only spirit active in the world, the author needs to qualify for the recipients how to tell if a spirit comes from God. The “test” is the confession in 4:2.

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.

¹ tn The interpretation of the three ὅτι clauses in v. 21 is very difficult: (1) All three instances of ὅτι (hoti) may be causal (so NASB, NIV, NEB). (2) The first two may be causal while the third indicates content (declarative or recitative ὅτι, so KJV, RSV, TEV, NRSV). (3) However, it is best to take all three instances as indicating content because this allows all three to be subordinate to the verb ἔγραψα (egrapsa) as compound direct objects. The author writes to reassure his readers (a) that they do indeed know the truth (first two uses of ὅτι) and (b) that no lie is of the truth (third use).

³ sn The reference to the darkness…passing away and the true light…already shining is an allusion to John 1:5, 9, and 8:12. Because the author sees the victory of light over darkness as something already begun, he is writing Jesus’ commandment to love one another to the readers as a reminder to (1) hold fast to what they have already heard (see 1 John 2:7) and (2) not be influenced by the teaching of the opponents.

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.

² sn Critics generally assume that 2 Peter is not authentic, partially because in vv. 15-16 Paul is said to have written scripture. It is assumed that a recognition of Paul’s writings as scripture could not have happened until early in the 2nd century. However, in the same breath that Paul is canonized, Peter also calls him “brother.” This is unparalleled in the 2nd century apocryphal works, as well as early patristic writings, in which the apostles are universally elevated above the author and readers; here, Peter simply says “he’s one of us.”
