Charles H. Spurgeon on Psalms 78:13

He divided the sea, and caused them to pass through. A double wonder, for when the waters were divided the bottom of the sea would naturally be in a very unfit state for the passage of so vast a host as that of Israel; it would in fact have been impassable, had not the Lord made the road for his people. Who else has ever led a nation through a sea? Yet the Lord has done this full often for his saints in providential deliverances, making a highway for them where nothing short of an almighty arm could have done so. And he made the waters to stand as an heap. He forbade a drop to fall upon his chosen, they felt no spray from the crystal walls on either hand. Fire will descend and water stand upright at the bidding of the Lord of all. The nature of creatures is not their own intrinsically, but is retained or altered at the will of him who first created them. The Lord can cause those evils which threaten to overwhelm us to suspend their ordinary actions, and become innocuous to us.
