1 John 3:14

3:14 We know that ¹  we have crossed over ²  from death to life ³  because ⁴  we love our fellow Christians. ⁵  The one who does not love remains in death. ⁶ 

1 John 3:23

3:23 Now ⁷  this is his commandment: ⁸  that we believe in the name of his Son Jesus Christ and love one another, just as he gave ⁹  us the commandment.

[3:14]  ¹ 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.

[3:14]  ² tn This verb essentially means “to transfer from one place to another, go/pass over,” according to BDAG 638 s.v. μεταβαίνω 1.

[3:14]  ³ sn Cf. John 5:24, where this phrase also occurs.

[3:14]  ⁴ 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.

[3:14]  ⁵ tn See note on the phrase “fellow Christian” in 2:9.

[3:14]  ⁶ 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.

[3:23]  ⁷ tn The καί (kai) is epexegetical/explanatory (or perhaps resumptive) of the commandment(s) mentioned in the preceding verse.

[3:23]  ⁸ 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.

[3:23]  ⁹ 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.
