Don't be a fool! It's true that at most you play the part of a little bolt in that great undertaking of Christ's.
But do you know what happens when a bolt is not tight enough or when it works itself out of place? Bigger parts also work loose or the gear-wheels get damaged and broken.
The work is slowed up. Perhaps the whole machine will be rendered useless.
What a big thing it is to be a little bolt!
