Western Civilization: How does ancient Greek religion differ from Hebrew religion?

The ancient Greeks religion was almost completely different from Hebrew religion in many ways. For one, the Greeks worshipped many Gods, such as Zeus, God of the Sky, Poseidon, God of the Sea, and Aphrodite, Goddess of love. They prayed or sacrificed to more than fifteen of these higher beings, depending on their need or problem. Paris made a deal with Aphrodite, to vote her as the most beautiful woman in a contest. If he followed her commands, he'd be granted his own wish, Helen of Troy. This is a classic example of how the Greeks viewed their deities. They were afraid of provoking the Gods to anger, and believed that had to be feared and appeased with gifts. 

They were also thought to be as temperamental and unreliable as we human beings. The Gods were liable to pride and lust, and other sinful tendencies. For instance, Nemesis is the Goddess of revenge. According to the Greeks, she would most likely intervene if things are going too well for you. She would cause something bad to happen, in order to keep you humble! Her sister, Fortuna was considered too generous by Nemesis, in her bestowal of wealth and good tidings. But even she was 50/50, in that you never knew whether you'd be blessed or cursed by her. It was a matter of luck and sheer chance. She is usually depicted holding the cornucopia, loaded with berries, meat, and other tasty food. This was supposed to represent all she had to offer her followers. Because of Fortuna, this basket is symbolic of our American holiday, Thanksgiving.

The Hebrews, on the other hand, only revered and loved one God. He is all-powerful and good, not capable of practicing deceit or committing atrocities. He won't be won over like a genie, by exchanging one thing for another. He also doesn't require human sacrifice, as was frequently practiced in Greece. This was firmly established by Abraham, father of the Hebrews. God tested his faith, by asking him to give up/kill his only son. When he saw Abraham's willingness, he told him to drew back his sword. Therefore, since that day, the Hebrew God has never expected or condoned human sacrifice towards him. Instead, Jews practice animal sacrifice, as Abraham did with the ram.
