Ecclesiastes 9:5-7

5For the living know that they will die, but the dead know nothing; they have no further reward, and even their name is forgotten.

6Their love, their hate and their jealousy have long since vanished; never again will they have a part in anything that happens under the sun. 7Go, eat your food with gladness, and drink your wine with a joyful heart, for God has already approved what you do.
