From the very beginning God said let there be light and it was so. Did you know Jesus who is known as the light of the world was in heaven with God the Father before even coming to the earth?( John 17:4-5 ), 4 I have glorified thee on the earth: I have finished the work which thou gavest me to do. 5 And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.( John 6:38-40 ).
God was the shining light for the Israelites as a pillar of fire to guide them ( Exodus 13:18-22 ).
Jesus was the great light in the wilderness spoken of in Isaiah, and who then fulfilled the prophecy in the book of Matthew! ( Isaiah 9:2-7 ), ( Matthew 4:13-19 ).
1 John 1:5-7 5 This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. 6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: 7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
