Charles Spurgeon Commentary Genesis 8:2

"the fountains also of the deep and the windows of heaven were stopped, and the rain from heaven was restrained;" — Genesis 8:2 (ASV)

God works upwards, and stops the windows of heaven. He works downwards, and restrains the breaking up of the fountains of the deep.

"He everywhere has sway,
And all things serve his might."

Do not be afraid; He can open the windows of heaven and pour down abundant blessings for you, and He can let down the cellar-flaps of the great deep and stop its flowing fountains.

"When He bares His arm,
What will His work withstand?"
