Mark 11:28-33

28 and demanded, "Show us your credentials. Who authorized you to speak and act like this?"

29 Jesus responded, "First let me ask you a question. Answer my question and then I'll present my credentials.

31 They were on the spot, and knew it. They pulled back into a huddle and whispered, "If we say 'heaven,' he'll ask us why we didn't believe John;

32 if we say 'humans,' we'll be up against it with the people because they all hold John up as a prophet."

33 They decided to concede that round to Jesus. "We don't know," they said. Jesus replied, "Then I won't answer your question either."
