Why is the concept of 'light' important for Christians?

Light is a central theme in Scripture, particularly in the Gospel of John. In John 1:4-5, it is stated that 'in Him was life, and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.' This illustrates that Christ not only provides life but also reveals divine truth in a world shrouded in spiritual darkness. For Christians, recognizing Christ as the source of light is crucial, as it affirms that our understanding, guidance, and hope are found in Him alone. His light exposes the darkness of sin and ignorance, enabling believers to walk in faith and obedience. Thus, 'light' represents the transformative power of the Gospel and the clarity it brings to the believer's life.
