Why is Christ called the light of the world?

In the sermon, Christ is contrasted with Lucifer, the so-called morning star, to highlight His true role as the light of the world. Isaiah had prophesied about the coming Messiah, who would bring hope and light to a people walking in darkness. As described in John 8:12, Jesus declares Himself as the light of the world, stating that those who follow Him will not walk in darkness but will have the light of life. This underscores the concept of redemption and spiritual illumination through Christ, distinguishing Him from the false aspirations of figures like Lucifer, who sought glory for themselves instead of reflecting God's true light.
