1 John 1:7

1:7 But if we walk in the light as he himself is in the light, we have fellowship with one another and the blood of Jesus his Son cleanses ¹  us from all sin. ² 

1 John 3:23

3:23 Now ³  this is his commandment: ⁴  that we believe in the name of his Son Jesus Christ and love one another, just as he gave ⁵  us the commandment.

1 John 4:7

God is Love

4:7 Dear friends, let us love one another, because ⁶  love is from God, and everyone who loves ⁷  has been fathered ⁸  by God and knows God.

[1:7]  ¹ tn Or “purifies.”

[1:7]  ² tn BDAG 50 s.v. ἁμαρτία 1 defines this term as “a departure fr. either human or divine standards of uprightness” (see 1 John 5:17 where ἁμαρτία [Jamartia] and ἀδικία [adikia] are related). This word occurs 17 times in 1 John, of which 11 are singular and 6 are plural.

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

[3:23]  ⁴ 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]  ⁵ 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.

[4:7]  ⁵ tn This ὅτι (Joti) is causal, giving the reason why the readers, as believers, ought to love one another: because love comes from God. The next clause, introduced by καί (kai), does not give a second reason (i.e., is not related to the ὅτι clause), but introduces a second and additional thought: Everyone who loves is fathered by God and knows God.

[4:7]  ⁶ tn As in 2:23 and 3:4, the author uses πᾶς (pas) with the present articular participle as a generalization to describe a category of people.

[4:7]  ⁷ tn The verb γεννάω (gennaw) in this context means to be fathered by God and thus a child of God. The imagery in 1 John is that of the male parent who fathers children (see especially 3:9 and 5:1).
