God said, 
Isa 55:9 “For as the heavens are higher than the earth, So are My ways higher than your ways, And My thoughts than your thoughts.
Hubble Telescope
God said, as the universe is higher than the earth so are
His ways higher than our own ways.
God made a scientific claim in His word about how far the universe stretches beyond our own abilities thousands of years ago when mankind had no idea there was a big universe out there. Today, even with the Hubble telescope we cannot even see the farthest star or galaxy. God's ways are just too great, and much higher than our own.
How big is the universe?
Beyond all human comprehension and perhaps trillions of trillions of times more than what we could possibly ever imagine. 
How big is God? The scriptures declare
1 Kings 8:27 NIV "But will God really dwell on earth? The heavens, even the highest heaven, cannot contain you."
The universe itself cannot contain God, He is just far too great!! God is beyond everything and anything in existence.
