John 2:19

19. Destroy this temple Our Lord gives them a sign, and at the same time a test. They are welcome to try the experiment. It was a suitable sign too; for as his mastery over the temple was the very point in question, he tells them he can rebuild the temple in a much shorter time than they can destroy it. Herein he asserts, as the eternal Son of God, his absolute omnipotence. It is this they understand; and they are so deeply impressed with the utterance that it meets him afterwards as a charge, namely, at his trial before their tribunal! That this was a true but not the only meaning will soon appear.
