What does the Bible say about the word of life?

The term 'word of life' in 1 John 1:1-4 refers fundamentally to Jesus Christ, who is described as the incarnate Word. This concept is also reflected in John 1:1, where it states that 'the Word was with God, and the Word was God.' Christ is the one through whom all things were made, as highlighted in the same chapter, and He represents the light and life that are essential for salvation. Therefore, the 'word of life' conveys not only the essential truths of God but also the person and work of Jesus Christ, through whom believers understand their relationship with the Father.
