Although I have not read Richard Dawkins' The God Delusion, apparently one of his key arguments against the existence of God is that the universe is huge and God would need to be even bigger and more awesome than the universe. Yes, Dr Dawkins, He would need to be and He is.
God needs nothing from us. He is the great I AM.
King David did not have a small view of God. Consider Psalm 97: 1-7.
The Lord reigns, let the earth rejoice;
let the many coastlands be glad!
Clouds and thick darkness are all around him;
righteousness and justice are the foundation of his throne.
Fire goes before him
and burns up his adversaries all around.
His lightnings light up the world;
the earth sees and trembles.
The mountains melt like wax before the Lord,
before the Lord of all the earth.
The heavens proclaim his righteousness,
and all the peoples see his glory.
All worshipers of images are put to shame,
who make their boast in worthless idols;
worship him, all you gods!
American Christians have a hard time understanding the concept of fear of God. David got it. So did Abram, Isaiah, Ezekiel, and John--all Godly men--all terrified in the presence of God. If you read about any of these men, you will discover that when they encountered the glory of God, they immediately fell on their face. I doubt they tenderly got to their knees and then slowly laid on the ground. They fell out.
It is only through Christ's sacrificial work on the cross that we can bear to be in the presence of our holy and powerful God. When it says to fear God, take it seriously. He is truly awesome. When we understand his awesomeness and what it means to fear Him, the gift of Christ on the cross will also lead us to a much deeper humility.
