“For with you is the fountain of life; in your light we see light.” (Ps 36:9)
We don’t see light. Light is the means by which we see. Our eyes can only comprehend things touched by light. In a manner of speaking light creates the things we see. God’s light; His illuminating insight, is the means by which we come to have illumination and insight. Things untouched by God’s light must remain in darkness.
