What does 'light and darkness' represent in the Bible?

The imagery of light and darkness is prevalent throughout Scripture, signifying a stark contrast between truth and falsehood, life and death, salvation and condemnation. Jesus refers to Himself as the 'light of the world' (John 8:12), representing the divine truth and life-giving power that dispels the darkness of sin and spiritual death. The darkness in this world symbolizes the fallen state of humanity, characterized by sin and rebellion against God. In John 11, Jesus' arrival at Lazarus' gravesite, where death reigns, illustrates His role as the light that enters into the darkness, conquering death and offering eternal life. This metaphor emphasizes the hope found in Christ—where His light shines, darkness cannot prevail, and those in spiritual blindness can receive sight and salvation. As Christians, understanding this dichotomy encourages us to embrace the light of Christ and walk in His truth.
