[4:7] 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.
[4:7] 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.
[4:7] 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.
[4:7] 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).
[4:11] 4 tn Grk “and.” The Greek conjunction καί (kai) introduces the apodosis of the conditional sentence.
[4:11] 5 tn This is a first-class conditional sentence with εἰ (ei) + aorist indicative in the protasis. Reality is assumed for the sake of argument with a first-class condition.
[4:11] sn The author here assumes the reality of the protasis (the “if” clause), which his recipients, as believers, would also be expected to agree with: Assuming that God has loved us in this way, then it follows that we also ought to love one another. God’s act of love in sending his Son into the world to be the atoning sacrifice for our sins (v. 10) ought to motivate us as believers to love one another in a similar sacrificial fashion. The author made the same point already in 1 John 3:16. But this failure to show love for fellow believers is just what the opponents are doing: In 1 John 3:17 the author charged them with refusing to love their brothers by withholding needed material assistance. By their failure to love the brothers sacrificially according to the example Jesus set for believers, the opponents have demonstrated again the falsity of their claims to love God and know God (see 1 John 2:9).
