Sufficient for the day is all that we can enjoy. We cannot eat or drink or wear more than the day's supply of food and raiment; the surplus gives us the care of storing it, and the anxiety of watching against a thief. One staff aids a traveller, but a bundle of staves is a heavy burden. Enough is not only as good as a feast, but is all that the greatest glutton can truly enjoy. This is all that we should expect; a craving for more than this is ungrateful. When our Father does not give us more, we should be content with his daily allowance.
