11 From the very first day, we were there, taking it all in - we heard it with our own ears, saw it with our own eyes, verified it with our own hands. 2 The Word of Life appeared right before our eyes; we saw it happen! And now we're telling you in most sober prose that what we witnessed was, incredibly, this: The infinite Life of God himself took shape before us. 3 We saw it, we heard it, and now we're telling you so you can experience it along with us, this experience of communion with the Father and his Son, Jesus Christ.
Matthew Henry's Commentary on 1 John 1:1-3
Commentary on 1 John 1:1-4
(Read 1 John 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.
