1 John 2:5 - Exposition

Once more (cf. 1 John 1:7 , 1 John 1:9 ) the opposite is stated and the thought carried further. But whoso keepeth his word , of a truth in him hath the love of God been perfected; i.e., as an accomplished fact; the relation of love has been established. In St. John ἀληθῶς is no mere expletive; it expresses reality, and reality that is known. From verse 4 we might have expected "of a truth he knoweth God;" but the apostle goes beyond this, and shows that really knowing God involves loving him. The context shows that τοῦ θεοῦ is objective—his love of God rather than God's love of him. The insertion of τοῦ θεοῦ here, and the drift of the Epistle thus far, are in favour of αὐτόν and αὐτοῦ in verses 3-5 meaning God rather than Christ, although αὐτός in verse 2 tells the other way. The last clause sums up and reaffirms, but as usual with a new turn of thought, the whole section (verses 3-5), which begins and ends with ἐν τούτῳ γινώσκομεν . Knowing God implies keeping his Word; and keeping his Word involves loving him; and all this implies being in him, i.e., having that fellowship with him and his Son in which the Christian's life (which is eternal life) consists, and to promote which St. John publishes his Gospel ( 1 John 1:3 , 1 John 1:4 ).
