1 John 3:18

Little children, let us not love with word or with tongue but in deed and truth. ¹ 

Ex 33:21; Mt 25:41-45; Ro 12:9; 1Co 13:4-7; Ga 5:13; Ga 6:1,2; Eph 4:1-3,15; 1Th 1:3; Jas 2:15,16; 1Pe 1:22; 1Jo 2:1

¹ 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.
