We expect rewards for goodness, and punishments for the bad things which we do. Often, they are not immediately forthcoming. Both evil and good exist in the life of the spirit, though, which is outside time, and though we may not see clear indications of reward or punishment, nevertheless, we feel reward or punishment with our conscience.
You should be in a hurry to do good works, even small ones, and to avoid sin. One good thing leads to another, and one sin causes another. The reward for virtue is virtue, and the punishment for vice is more vice.
—The TALMUD
The worst punishment is the understanding that you failed to properly use those good things which were given to you. Do not expect a big punishment. There can be no harder punishment than this remorse.
You seek the cause of evil, and it is only in yourself.
—JEAN JACQUES ROUSSEAU
Doing good is the only sure path to bliss.
Do not expect some tangible reward for your goodness; your actions are their own reward. In the same way, do not think that you can hope to avoid punishment of your evil acts, for your punishment already lies in your soul. You are mistaken if you think that the pain in your soul was caused by anything else.
