Verse-by-Verse Study
1 John 1:1
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;
Study: John begins by emphasizing the tangible reality of Jesus, the Word of life, who existed from the beginning. This stresses the apostolic eyewitness testimony, grounding faith in historical truth rather than myth.

That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.
