Our forefather Abraham (Avraham Avinu) stood up against the entire world. At that time, everyone worshipped idols. He was one person against the multitude. He stood up against falseness and lies. The whole world was against him. Nimrod tried to kill him by throwing him in a fiery furnace. His own father Terach tried to kill him. But Avraham did not care. He knew the truth. He understood about the Creator o f the world and he stood up against all lies and spent his life spreading the truth to others.
