We do not know: The religious leaders of the nation admitted that they could not answer a simple question that the people had no difficulty in answering: John was sent from God. This response showed the Jewish leaders were not fit to lead on this issue. Their stubbornness, lack of desire to understand, and refusal to accept the truth made further discussion without purpose (3:5; 7:6; 4:12).
God's judgment would come within that very generation (13:30) because of:
their spiritual blindness and opposition toward God's servants, John the Baptist and Jesus,
their lack of respect for the temple, and
their plot to kill Jesus.
