In The Valley of Vision, a collection of Puritan prayers, I read this:

The thought of thine infinite serenity cheers me…

There is no hint of anxiety with God. All is peaceful, infinitely peaceful.

No wringing of the hands.

How should that cheer me?

He is not fearful as if there is something unknown or unaccounted for. All is subject to Him and under His authority.

An earthly dictator might have all under his control too but God is not some distant dictator.

He is my faithful Father and good shepherd. Fathers and shepherds are very near and are constantly protecting and watching.

This Father, this Shepherd, is perfectly peaceful, not troubled, but in complete control.

This cheers me.
