Mark 11: 29, 30: “And Jesus said to them, ‘I will ask you one question, and you answer Me, and then I will tell you by what authority I do these things. Was the baptism of John from Heaven, or from men? Answer Me.’” These guys had seated themselves in Moses’ seat, and were already rewriting and replacing his commandments (Mark 7: 9-13). They came to Jesus asking for His source of authority for one reason: they thought they were the source of all authority; so Jesus asked them a question that, however they answered it, would revealed this pomposity. But His seceding parable reminded them, and everyone: you can pretend that God has placed no authority over you, but eventually He will prove you wrong.
