We cannot “over expect” God

Open your mouth wide, and I will fill it.
Psalm 81: 10

You may easily over expect the creature, but you cannot over expect God: “Open thy mouth wide, and I will fill it”; widen and dilate the desires and expectations of your souls, and God is able to fill every chink to the vastest capacity. This honours God, when we greaten our expectations upon him, it is a sanctifying of God in our hearts.

Thomas Case (1598-1682), in “Morning Exercises” as quoted by C. H Spurgeon in the Treasury of David
