Discovery Box1 John 3:10 
Context3:10 By this 1 the children of God and the children of the devil are revealed: Everyone who does not practice righteousness – the one who does not love his fellow Christian 2 – is not of God.
1 John 3:24
Context3:24 And the person who keeps his commandments resides 3 in God, 4 and God 5 in him. Now by this 6 we know that God 7 resides in us: by the Spirit he has given us.
1 tn Once again there is the problem (by now familiar to the interpreter of 1 John) of determining whether the phrase ἐν τούτῳ (en toutw) in 3:10 refers (1) to what precedes or (2) to what follows. If it refers to what precedes, it serves to conclude the unit which began with 2:28. The remainder of 3:10 would then form a transition to the following material (another “hinge” passage). On the other hand, if the phrase ἐν τούτῳ refers to what follows, then the entirety of 3:10 is a summary statement at the end of 2:28-3:10 which recapitulates the section’s major theme (conduct is the clue to paternity), and provides at the same time a transition to the theme of loving one’s brother which will dominate the following section (3:11-24). Although R. E. Brown (Epistles of John [AB], 416) prefers to see the phrase as referring to the preceding material, it makes better sense to refer it to the remainder of 3:10 that follows, and see the entirety of 3:10 as both a summary of the theme of the preceding section 2:28-3:10 and a transition to the following section 3:11-24.
2 tn See note on the term “fellow Christian” in 2:9.
sn Does not love his fellow Christian. The theme of loving one’s fellow Christian appears in the final clause of 3:10 because it provides the transition to the second major section of 1 John, 3:11-5:12, and specifically to the following section 3:11-24. The theme of love will dominate the second major section of the letter (see 1 John 4:8).
3 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).
4 tn Grk “in him.” In context this is almost certainly a reference to God (note the phrase “his Son Jesus Christ” in 3:23).
5 tn Grk “he.” In context this is almost certainly a reference to God (note the phrase “his Son Jesus Christ” in 3:23).
6 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.
7 tn Grk “he.” In context this is almost certainly a reference to God (note the phrase “his Son Jesus Christ” in 3:23).
