What does the Bible say about life and light in Christ?

In John 1:4-5, it states, 'In him was life, and that life was the light of men.' This passage encapsulates the profound theological truth that all life, both natural and spiritual, is found in Jesus Christ. He is the source of life, and it is through Him that understanding and wisdom are imparted to humanity. Without Him, there is only darkness, and true understanding is impossible. The light shines in darkness, emphasizing that the spiritual truths of God are revealed through Christ, providing clarity where none exists. Natural man, in his fallen state, cannot comprehend this light, which leads to a separation from the life that Christ offers.
