How do we know that Jesus is the light of life?

Jesus being the light of life is rooted in His divine nature as the eternal Son of God, who demonstrates God's revelation to humanity. His claim in John 8:12 showcases His authority, indicating that without Him, one remains in darkness. This light not only guides but also gives life and insight into God's holiness, leading believers out of the darkness of sin. The significance of this revelation is critical for understanding salvation as it ensures that followers are transformed by His light into vessels of His grace.
