How do we know that the light represents Christ?

In the sermon, it is clearly stated that Jesus Christ is the light that reveals God to humanity. John 8:12 declares, 'I am the light of the world; he that followeth me shall not walk in darkness, but shall have the light of life.' This affirms that Christ is not only the one who brings light but also embodies the light that reveals God's nature. He is the final and complete disclosure of God, surpassing all previous revelations found in the Old Testament through prophets, thus providing believers with the true understanding of God’s character and intentions.
