Verse 4. - While verses 1-3 refer to the Gospel, this refers to the Epistle; but, although ταῦτα in 1 John 2:26 and 1 John 5:13 refer to what precedes, there is no need to limit ταῦτα here to these opening verses; it covers the whole Epistle. The reading ἡμεῖς seems preferable to ὑμῖν, and ἡμῶν to ὑμῶν. But ἡμεῖς and ἡμῶν are not coordinate: ἡμεῖς is the apostolic "we;" ἡμῶν means "your joy as well as mine." This verse takes the place of the usual "grace and peace" in the opening of other Epistles; and as verse 3 recalls John 17:21, so this recalls John 17:13. The joy is that of knowing that, though in the world, they are not of it, but are one with one another, and with the Father and with the Son. The gospel is always joy: "Rejoice alway" (1 Thessalonians 5:16); "Rejoice in the Lord alway" (Philippians 4:4). To know that the Eternal Life has been manifested, that we have communion with him, and through him with the Father, must be joy. Whereas Gnosticism, by denying the atonement, and "the personal office of God in the salvation of the world," cuts off one great sphere of God's love, and consequently one great cause of the believer's joy. To sum up this introduction: St. John gives his Gospel to the Church ἀπαγγέλλομεν in order that all may share in the union for which Christ prayed; and to the Gospel he adds this Epistle καὶ ταῦτα γράφομεν, that all may realize the joy resulting from this union - that our joy may be fulfilled. In this introduction we find the following expressions which are characteristic of St. John, serving to show the common authorship of the Gospel and Epistle, and in some cases of the Revelation also: ὁ Λόγος ἡ ζωή φανερόω μαρτυρέω ζωὴ αἰώνιος η΅ν πρός ἡ χαρὰ η΅ι πεπληρωμένη. It is among the many excellences of the Revised Version that characteristic expressions are marked by a uniform translation; whereas in the Authorized Version they are obscured by capriciously varying the translation: e.g. μαρτυρέω is rendered in four different ways - "bear witness," "bear record," "give record," "testify" (cf. page 10).

1:1-4 That essential Good, that uncreated Excellence, which had been from the beginning, from eternity, as equal with the Father, and which at length appeared in human nature for the salvation of sinners, was the great subject concerning which the apostle wrote to his brethren. The apostles had seen Him while they witnessed his wisdom and holiness, his miracles, and love and mercy, during some years, till they saw him crucified for sinners, and afterwards risen from the dead. They touched him, so as to have full proof of his resurrection. This Divine Person, the Word of life, the Word of God, appeared in human nature, that he might be the Author and Giver of eternal life to mankind, through the redemption of his blood, and the influence of his new-creating Spirit. The apostles declared what they had seen and heard, that believers might share their comforts and everlasting advantages. They had free access to God the Father. They had a happy experience of the truth in their souls, and showed its excellence in their lives. This communion of believers with the Father and the Son, is begun and kept up by the influences of the Holy Spirit. The benefits Christ bestows, are not like the scanty possessions of the world, causing jealousies in others; but the joy and happiness of communion with God is all-sufficient, so that any number may partake of it; and all who are warranted to say, that truly their fellowship is with the Father, will desire to lead others to partake of the same blessedness.And these things write we unto you,.... Concerning the deity and eternity of Christ, the Word and concerning the truth of his humanity, and the manifestation of him in the flesh; and concerning that eternal life and salvation which is declared in the Gospel to be in him; and concerning the saints' fellowship one with another, and with God the Father, and with Jesus Christ:

that your joy may be full; meaning either their spiritual joy in this life, which has Christ for its object, and is increased by the consideration of his proper deity, his incarnation and mediation by a view of free justification by his righteousness, and atonement by his blood; by a sight of his glorious person by faith, and by intimate communion with him, and a discovery of his love, which passeth knowledge: and which joy, when it is large, and very great, may, in a comparative sense, be said to be full, though not absolutely so, and being as much as can well be enjoyed in this state; and nothing can more contribute to it than a declaration of the above things in the Gospel, and an experimental acquaintance with them, and enjoyment of them: or else it may intend the joy of the saints in the world to come, in the presence of Christ, where are fulness of joy, and pleasures for evermore; and so may express the ultimate glory and happiness of God's people, which is the chief end, as of his purposes, promises, and covenant, so of the Gospel, and the declaration of it. The Syriac version renders it, "that our joy, which is in you, may be full"; it is the joy of the ministers of the word, when the saints are established in the faith of Christ's person and offices, and have communion with him, with which view they declare him, and bear record of him. Some copies read, our joy.
