[3:7] 1 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] 2 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.
[3:18] 3 sn The noun truth here has been interpreted in various ways: (1) There are a number of interpreters who understand the final noun in this series, truth (ἀληθείᾳ, alhqeia) in an adverbial sense (“truly” or “in sincerity”), describing the way in which believers are to love. If the two pairs of nouns are compared, however, it is hard to see how the second noun with tongue (γλώσσῃ, glwssh) in the first pair can have an adverbial sense. (2) It seems better to understand the first noun in each pair as produced by the second noun: Words are produced by the tongue, and the (righteous) deeds with which believers are to love one another are produced by the truth.
