How do we know Christ is the light of the world?

Christ is referred to as the light of the world in John 8:12, where He proclaims, '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 highlights His role in illuminating spiritual truths and providing salvation. Just as stars reflect the light of the sun, believers are called to reflect Christ's light in their lives, acting as conduits of His love and truth to a lost world. This reflection is essential for the mission of the Church and is empowered by the Holy Spirit.
