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.

4. these things—and none other, namely, this whole Epistle.

write we unto you—Some oldest manuscripts omit "unto you," and emphasize "we." Thus the antithesis is between "we" (apostles and eye-witnesses) and "your." We write thus that your joy may be full. Other oldest manuscripts and versions read "OUR joy," namely, that our joy may be filled full by bringing you also into fellowship with the Father and Son. (Compare Joh 4:36, end; Php 2:2, "Fulfil ye my joy," Php 2:16; 4:1; 2Jo 8). It is possible that "your" may be a correction of transcribers to make this verse harmonize with Joh 15:11; 16:24; however, as John often repeats favorite phrases, he may do so here, so "your" may be from himself. So 2Jo 12, "your" in oldest manuscripts. The authority of manuscripts and versions on both sides here is almost evenly balanced. Christ Himself is the source, object, and center of His people's joy (compare 1Jo 1:3, end); it is in fellowship with Him that we have joy, the fruit of faith.
