We are told in the first Epistle of John, the first chapter: "This is the message we have received from him and proclaim to you, that God is light and in him there is no darkness at all." Is this a figure of speech or a literal fact? I am telling you from experience: it is a literal fact, for God is light!
There are three very firm statements made in scripture defining God. God is light. God is love, and God is spirit. John tells us here that God is light, a light in which there is no darkness. Now try to follow me closely. The final gift to man is God himself and God is a revealer. Man's knowledge of himself is based on his knowledge of the revealer. Scripture records what is said of the revealer. As he awakens in you, read scripture carefully and you will discover to what extent God has revealed himself to you.
