How do we know Jesus Christ is the Word of Life?

In the beginning of his epistle, John asserts that Jesus Christ is the Word of life, affirming His pre-existence and divine nature. This is echoed in John 1:1 where it states, 'In the beginning was the Word, and the Word was with God, and the Word was God.' John's eyewitness testimony adds credibility to this claim, as he declares that they have both heard and seen Him. This knowledge is foundational for believers, as it shapes their understanding of who Christ is and their relationship with Him. Understanding Christ as the Word of life lays the groundwork for the joy and assurance of salvation He provides.
