[3:5] 1 tn Grk “that one.” The context makes it clear that this is a reference to Jesus, because the reader is told “he was revealed in order that he might take away sins.” The connection with Jesus as the Lamb of God who takes away the sin of the world in John 1:29 provides additional confirmation that the previous use of ἐκεῖνος (ekeinos) in 3:3b should also be understood as a reference to Jesus, as 2:6 was.
[3:5] sn In Johannine thought it is Jesus, the Lamb of God, who takes away the sin of the world (John 1:29).
[3:5] 2 tn The ἵνα (Jina) clause gives the purpose of Jesus’ self-revelation as he manifested himself to the disciples and to the world during his earthly life and ministry: It was “to take away sins.”
[3:7] 3 sn The one who practices righteousness. The participle (ὁ ποιῶν, Jo poiwn) + noun constructions in 3:7 and in 3:8a, the first positive and the second negative, serve to emphasize the contrast between the true Christians (“the one who practices righteousness”) and the opponents (“the one who practices sin,” 3:8a).
[3:7] 4 tn Grk “that one.” Context indicates a reference to Jesus here. As with the previous uses of ἐκεῖνος (ekeinos) by the author of 1 John (2:6; 3:3, 5), this one refers to Jesus, as the reference to “the Son of God” in the following verse (3:8) makes clear.
