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

In 1 John 1:1, Christ is described as the Word of Life, indicating His divine nature and essential role as both the source and sustainer of life. The title 'Word' signifies His preexistence and authority as God incarnate. Through His life, death, and resurrection, He has fully manifested the nature of God, offering eternal life to all who believe. Thus, when we proclaim Christ, we present the only true source of life and salvation, inviting others to find hope and redemption through Him.
