And while we are thinking of the vastness of the universe, the vastness of space--which we can only measure in light-years for lack of a better way to measure it--remember, He is the light.  John 12:36 "While you have light, believe in the light that you may be children of the light."

John 1:1,4-5  "In the beginning was the Word, and the Word was with God, and the Word was God...In him was life; and the life was the light of men.  And the light shined in the darkness; and the darkness  comprehended it not."

Romans 1: 20-22 "For the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and God-head; so that they are without excuse:  Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.  Professing themselves to be wise, they became fools..."

They became fools.  It is all visible to the human eye.  You have to look.  You have to ask the eternal question, "Where did all of this come from?"  And then you have to decide:  Accident, or Creator.  It seems evident.  But those who do not want to answer to a Holy God, those who do not want to come under the authority of a creator, "become vain in their imagination, darken their hearts, and profess themselves to be wise."

How foolish.

"The invisible things are clearly seen."
