Why is Christ described as the light of the world?

Christ is referred to as the light of the world in John 8:12, where He states, "I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life." This declaration signifies that Jesus embodies the truth of God's revelation, providing spiritual illumination that dispels darkness, which represents sin and ignorance. In Psalm 27:1, David proclaims, "The Lord is my light and my salvation; whom shall I fear?" This underscores the importance of Christ in guiding believers and providing salvation. By believing in Him, we gain not only understanding but also the assurance of eternal life and the strength to face life's challenges without fear.
