¹ tn It could be argued (1) that the ὅτι (Joti) at the beginning of 3:11 is grammatically subordinate to the preceding statement at the end of 3:10. As BDF §456.1 points out, however, “Subordination with ὅτι and διότι is often very loose…and must be translated ‘for.’” Thus (2) ὅτι assumes an inferential sense, standing at the beginning of a new sentence and drawing an inference based upon all that has preceded. This is confirmed by the structural parallel between the present verse and 1:5.

² tn The word “gospel” is not in the Greek text but is supplied to clarify the meaning. See the notes on the words “gospel” and “message” in 1 John 1:5.

³ tn See the note on the word “message” in 1 John 1:5, where this same phrase occurs.

⁴ sn For this is the gospel message…that we should love one another. The structure of this verse is parallel to 1:5, indicating the beginning of a second major section of the letter.

⁵ tn The first ὅτι (Joti) 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 (ginwskw) 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.

⁶ tn This verb essentially means “to transfer from one place to another, go/pass over,” according to BDAG 638 s.v. μεταβαίνω 1.

sn In John 13:1 the same Greek verb translated crossed over here is used to refer to Jesus’ departure from this world as he returns to the Father. Here it is used figuratively to refer to the believer’s transfer from the state of (spiritual) death to the state of (spiritual) life. This use is paralleled in John 5:24, where Jesus states, “the person who hears my message and believes the one who sent me has eternal life and will not be condemned, but has crossed over (same verb) from death to life.”

⁷ sn Cf. John 5:24, where this phrase also occurs.

⁸ tn The second ὅτι (Joti) clause in 3:14 is also related to οἴδαμεν (oidamen), but in this case the ὅτι is causal, giving the reason why the readers know that they have passed from death to life: because they love the brothers.

⁹ tn See note on the phrase “fellow Christian” in 2:9.

sn Because we love our fellow Christians. This echoes Jesus’ words in John 13:35, where he states, “by this all men will know that you are My disciples, if you have love for one another.” As in 1 John 2:3 and 5, obedience becomes the basis for assurance. But the relationship between loving one’s fellow Christian (Grk “brother”) and possessing eternal life goes beyond a proof or external test. Our love for our fellow Christians is in fact a form of God’s love for us because as far as the author of 1 John is concerned, all love comes from God (cf. 4:7-11). Therefore he can add the next line of 3:14, “the one who does not love remains in death.” Why? Because such a person does not have God’s love residing in them at all. Rather, this person can be described as a “murderer” – as the following verse goes on to do. Note also that the author’s description here of the person who does not love as remaining in death is another way of describing a person who remains in darkness, which is a description of unbelievers in John 12:46. This provides further confirmation of the spiritual state of the author’s opponents in 2:9-11.

¹⁰ sn The one who does not love remains in death. Again, the author has the secessionist opponents in view. Their refusal to show love for the brothers demonstrates that they have not made the transition from (spiritual) death to (spiritual) life, but instead have remained in a state of (spiritual) death.

¹¹ sn The noun truth here has been interpreted in various ways: (1) There are a number of interpreters who understand the final noun in this series, truth (ἀληθείᾳ, alhqeia) in an adverbial sense (“truly” or “in sincerity”), describing the way in which believers are to love. If the two pairs of nouns are compared, however, it is hard to see how the second noun with tongue (γλώσσῃ, glwssh) in the first pair can have an adverbial sense. (2) It seems better to understand the first noun in each pair as produced by the second noun: Words are produced by the tongue, and the (righteous) deeds with which believers are to love one another are produced by the truth.

¹² tn The καί (kai) is epexegetical/explanatory (or perhaps resumptive) of the commandment(s) mentioned in the preceding verse.

¹³ tn This verse begins with the phrase καὶ αὕτη ἐστίν (kai {auth estin; cf. the similar phrase in 3:11 and 1:5), which is explained by the following ἵνα (Jina) clause, “that we believe in the name of his Son Jesus Christ.” The ἵνα thus introduces a clause which is (1) epexegetical (explanatory) or (2) appositional. By analogy the similar phrase in 3:11 is also followed by an epexegetical ἵνα clause and the phrase in 1:5 by an epexegetical ὅτι (Joti) clause.

sn His commandment refers to what follows – the commandment from God is to believe in his Son, Jesus Christ, and to love one another.

¹⁴ sn The author of 1 John repeatedly attributes the commandments given to believers as given by God the Father, even though in John 13:34-35 it was Jesus who gave the commandment to love one another. 2 John 4-5 also attributes the commandment to love one another directly to the Father. Thus it is clear that God the Father is the subject of the verb gave here in 3:23.
