Luk 11:34 Your eye is the lamp of your body. When your eyes are healthy, your whole body also is full of light. But when they are unhealthy, your body also is full of darkness.
In spiritual creation God brings light to the hearts of those in darkness. Confronted with the risen Lord, we became a new creation. The light in believers’ lives is the knowledge of God’s salvation, a glory issuing from and seen in the face of Christ and reflected by us. When people were in the darkness of sin, they had no knowledge of God, no experience of His life and salvation.
