If a man feels that what, without any fault of his own, he suffers in this life can only be the result of some of his former acts, he will bear his sufferings with more resignation, like a debtor who is paying off an old debt. And if he knows besides that in this life he may actually lay by moral capital for the future, he has a motive for goodness, which is not more selfish than it ought to be. The belief that no act, whether good or bad, can be lost, is only the same belief in the moral world which our belief in the preservation of force is in the physical world. Nothing is lost.
