God’s promises are not exhausted when they are fulfilled, for when once
performed, they stand just as good as they did before, and we may wait a
second accomplishment of them. Man’s promises, even at the best, are
like a cistern which holds but a temporary supply; but God’s promises
are as a fountain, never emptied, ever overflowing, so you may draw from
them the whole measure of that which they apparently contain, and they
shall be still as full as ever.
