And if you are wrong , eternity is a long time.

[MountainsWinAgain]

How can you be so arrogant to think that your actions during a few short years on earth would decide your fate for an eternity?

And another thing:
But there are no gods which threaten us, and, even if there were, we would not be there to be punished. Our souls are flimsy things which are dissipated when we die, and even if the stuff of which they were made were to survive intact, that would be nothing to us, because what matters to us is the continuity of our experience, which is severed by the parting of body and soul. It is not sensible to be afraid of ceasing to exist, since you already know what it is like not to exist; consider any time before your birth-was it disagreeable not to exist?

Teaching of Epicurus

Edit:
"Don't fear god." The gods are happy and immortal, as the very concept of 'god' indicates. But in Epicurus' view, most people were in a state of confusion about the gods, believing them to be intensely concerned about what human beings were up to and exerting tremendous effort to favor their worshipers and punish their mortal enemies. No; it is incompatible with the concept of divinity to suppose that the gods exert themselves or that they have any concerns at all. The most accurate, as well as the most agreeable, conception of the gods is to think of them, as the Greeks often did, in a state of bliss, unconcerned about anything, without needs, invulnerable to any harm, and generally living an enviable life.
