What does the light and darkness metaphor mean in John 1?

In John 1:5, it is stated, 'And the light shineth in darkness; and the darkness comprehended it not.' This metaphor is significant as it illustrates the struggle between Christ, who is the true Light, and the darkness of sin that envelops humanity. The darkness, which originated from Adam’s fall (Romans 5:12), represents spiritual blindness and separation from God. Only through Christ’s light can individuals recognize their sinful state and seek redemption. This understanding invites believers to embrace the truth of the Gospel as it illuminates their path, moving them from darkness into the glorious light of salvation.
