He ordered the idolaters to bring their gods in and have them explain the flow of past history. Can they explain history? Are they able to explain how past events will unfold in the future? Can they predict the future and bring it to pass? In a word, are they transcendent? This would prove that they were really gods. Indeed, the Lord challenged: Have them do anything, good or bad, so that they might have some real effect on people. [source][source][source]
