[3:16] 1 tn Here the phrase ἐν τούτῳ (en toutw) is followed by a ὅτι (Joti) clause which is epexegetical (or explanatory), and thus ἐν τούτῳ refers to what follows.
[3:16] 2 tn Grk “that one.” Context indicates a reference to Jesus. The mention of the sacrificial death in 3:16 (ὑπὲρ ἡμῶν τὴν ψυχὴν αὐτοῦ ἔθηκεν, Juper hmwn thn yuchn autou eqhken) points to Jesus as the referent here. (This provides further confirmation that ἐκεῖνος [ekeinos] in 2:6; 3:3, 5, and 7 refers to Jesus.)
[3:16] 3 sn References to the fact that Jesus laid down his life using the verb τίθημι (tiqhmi) are unique to the Gospel of John (10:11, 15, 17, 18; 13:37, 38; 15:13) and 1 John (only here). From John’s perspective Jesus’ act in giving up his life sacrificially was a voluntary one; Jesus was always completely in control of the situation surrounding his arrest, trials, and crucifixion (see John 10:18). There is a parallel with 1 John 2:6 – there, as here, the life of Jesus (during his earthly ministry) becomes the example for believers to follow. This in turn underscores the importance of Jesus’ earthly life and ministry (especially his sacrificial death on the cross), a point of contention between the author and his opponents in 1 John. See 1 John 4:10 for a further parallel.
[4:13] 4 tn Again whether the referent of the phrase ἐν τούτῳ (en toutw) (1) precedes or (2) follows is a problem. This time there are two ὅτι (Joti) clauses which follow. The first is an indirect discourse clause related to γινώσκομεν (ginwskomen) and giving the content of what believers know: “that we reside in him and he in us.” The second ὅτι clause is epexegetical (or explanatory) to the ἐν τούτῳ phrase, explaining how believers know that they reside in God and God remains in them: “in that he has given us of his Spirit.”
[4:13] sn By this we know. According to the author of 1 John, the Father’s giving of the indwelling Holy Spirit to the believer is one means of providing assurance to the believer of his relationship to God. This is what was also stated in 1 John 3:24b in essentially identical terms.
[4:13] 5 tn Grk “in him.” Context indicates that the pronoun refers to God (see 4:12).
[4:13] 6 sn The genitive of his Spirit here, like the phrase in 3:24, probably reflects a partitive nuance, so that the author portrays God as ‘apportioning’ his Spirit to individual believers. This leads to the important observation that the author is not particularly interested in emphasizing (1) the ongoing interior witness of the Holy Spirit (which is what the passage is often understood to mean) but is emphasizing (2) the fact that God has given the Spirit to believers, and it is this fact that gives believers assurance of their relationship to God. In other words, it is the fact that the Holy Spirit has been given to believers, rather than the ongoing interior testimony of the Holy Spirit within the believer, which is the primary source of the believer’s assurance.
