From the book Abraham by Bruce Feiler, describing his conversation with an American who came to Jerusalem after winning fourteen thousand dollars on Wheel of Fortune:
He decided to come to Israel for a year. Fifteen years later he hadn’t left. He tells a story to answer why.
Two brothers live on either side of a hill. One is wealthy and has no family; the other has a large family but limited wealth. The rich brother decides one night that he is blessed with goods and, taking a sack of grain from his silo, carries it to the silo of his brother. The other brother decides that he is blessed with many children, and since his brother should at least have wealth, he takes a sack of grain from his silo and carries it to that of his brother. Each night they go through this process, and every morning each brother is astounded that he has the same amount of grain as the day before. Finally one night they meet at the top of the hill and realize what’s been happening. They embrace and kiss each other.
And at that moment a heavenly voice declares, “This is the place where I can build my house on earth.”
“That story is shared by all three religions,” David said. “And our tradition says that this is that hill, long before the Temple, long before Abraham. And the point of the story is that this degree of brotherly love is necessary before God can be manifest in the world.”
“This is not only the spot where it is possible to connect with God, it’s the spot where you can connect with God only if you understand what it means to connect with one another.
“The relationship between a person and another human being is what creates and allows for a relationship with God. If you’re not capable of living with each other and getting along with each other, then you’re not capable of having a relationship with God.” He gestured up at the Wall, the Dome, the churches.
Then he turned back to me. “So the question is not whether God can bring peace into the world. The question is: Can we?”
