1 tn The καί (kai) is epexegetical/explanatory (or perhaps resumptive) of the commandment(s) mentioned in the preceding verse.
2 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.
3 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.
4 tn The verb μένω (menw) has been translated “resides” here because this verse refers to the mutual and reciprocal relationship between God and the believer.
sn The verb resides (μένω, menw) here and again in the second clause of 3:24 refers to the permanence of relationship between God and the believer, as also in 2:6; 4:12, 13, 15, and 16 (3x).
5 tn Grk “in him.” In context this is almost certainly a reference to God (note the phrase “his Son Jesus Christ” in 3:23).
6 tn Grk “he.” In context this is almost certainly a reference to God (note the phrase “his Son Jesus Christ” in 3:23).
7 tn Once again there is the (by now familiar) question of whether the phrase ἐν τούτῳ (en toutw) refers to what precedes or to what follows. In this case, the following phrase ἐκ τοῦ πνεύματος (ek tou pneumato") explains the ἐν τούτῳ phrase, and so it refers to what follows.
8 tn Grk “he.” In context this is almost certainly a reference to God (note the phrase “his Son Jesus Christ” in 3:23).
