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

Christ's claim as the light of the world is foundational in the New Testament, specifically highlighted in verses such as John 8:12, where He states, 'I am the light of the world; he who follows Me will not walk in darkness, but will have the light of life.' This proclamation establishes His divine authority and the transformative impact of His presence in the lives of believers. Furthermore, the Old Testament tabernacle's candlestick serves as a foreshadowing of this truth, signifying that the true light comes from God and reveals our need for salvation through Christ. His role as the light connects to themes of revelation, grace, and spiritual awakening, confirming His centrality in the believer's understanding of God.
