in general I think we should be very cautious about promising and providing rewards and punishments. Because life rarely has its rewards and punishments; usually sacrifices have no reward, and often evil deeds go unpunished, at times they are even richly rewarded with success and money. Therefore it is best that our children should know from infancy that good is not rewarded and that evil goes unpunished; yet they must love good and hate evil, and it is not possible to give any logical explanation for this.
