Discovery Box1 John 4:7-8 
Context4:7 Dear friends, let us love one another, because 1 love is from God, and everyone who loves 2 has been fathered 3 by God and knows God. 4:8 The person who does not love does not know God, because God is love. 4
1 John 4:21
Context4:21 And the commandment we have from him is this: that 5 the one who loves God should love his fellow Christian 6 too.
1 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.
2 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.
sn From the author’s “either/or” perspective (which tends to see things in terms of polar opposites) the use of a generalization like everyone who presents a way of categorizing the opponents on the one hand and the recipients, whom the author regards as genuine Christians, on the other. Thus everyone who loves refers to all true Christians, who give evidence by their love for one another that they have indeed been begotten by God and are thus God’s children. The opposite situation is described in the following verse, 4:8, where (although everyone [πᾶς, pas] is omitted) it is clear that a contrast is intended.
3 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).
4 tn The author proclaims in 4:8 ὁ θεὸς ἀγάπη ἐστίν (Jo qeo" agaph 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.
5 tn The ἵνα (Jina) 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 (tauthn) 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.”
