Paul Kjoss Helseth illustrates the peace in believing God controls all things:

Shortly after the Battle of Manassas in Ronald Maxwell’s film adaptation of Jeffrey Shaara’s historical novel Gods and Generals, a shell-shocked captain in the Confederate army asks Lieutenant General Thomas “Stonewall” Jackson how he could remain so tranquil in battle when the fight was raging all around him. “General,” the young captain asks in an almost reverential tone, “how is it that you can keep so serene and stay so utterly insensible, with a storm of shells and bullets raining about your head?” Jackson’s response reveals his unshakable confidence in the absolute sovereignty of God over all things, including the seemingly random events that take place on the battlefield. “Captain Smith,” Jackson thoughtfully responds, “my religious belief teaches me to feel as safe in battle as in bed. God has fixed the time for my death; I do not concern myself with that, but to be always ready, whenever it may overtake me. That is the way all men should live; then all men would be equally brave.”

What is interesting about this example is that Stonewall later is shot to death accidentally by his own men. He is shot, his arm has to be removed, and then he ultimately succumbed to pneumonia eight days later. The believe that God controls all things by necessity means that God has predestined all nonsense from before time eternal. Not quite a heartening idea:
