In him (The Word) was life, and that life was the light of humanity (John 1:4). 

The Word did not remain distant; he became flesh and made his dwelling among us. While walking in the world, he declared, “I am the light of the world. Whoever follows me will never walk in darkness but will have the light of life.” Notice what he did not say: “I have the light and I will hand it to you in a book.” No—he says, “I am the light.” Life is in him, and that life shines outward as light. Those who receive him do not merely gain information; they step out of darkness and into the light of life.

Without Jesus, we remain in darkness. In darkness, we misunderstand God and easily believe false stories about him. We imagine a distant judge, an indifferent creator, or a God who must be appeased. Darkness also distorts our understanding of ourselves. We measure our worth by failure, shame, success, or comparison, and we accept lies about who we are. But when Jesus, the light of the world, enters our lives, truth begins to break through. His light exposes the lies and leads us into reality.

For John, light is not merely an idea or doctrine; light is a person who lives in relationship with the Father and invites us into that relationship. This challenges the way people think about enlightenment. Some “religious” people seem to suggest that enlightenment comes through mastering ideas or accepting propositions. Yet it is possible to agree with “truths” and still live in darkness. Illumination comes as we walk with Jesus. As we follow him, the Spirit shines light into our dark hearts, revealing who God is and who we are.
