Albert Barnes on John 15:24

The works which none other man did. The miracles of Jesus surpassed those of Moses and the prophets--

1st. In their number. He healed great multitudes, and no small part of his life was occupied in doing good by miraculous power.

2nd. In their nature. They involved a greater exertion of power. He healed all forms of disease. He showed that his power was superior to all kinds of pain. He raised Lazarus after he had been four days dead. He probably refers also to the fact that he had performed miracles of a different kind from all the prophets.

3rd. He did all this by his own power; Moses and the prophets by the invoked power of God. Jesus spake and it was done, showing that he had power of himself to do more than all the ancient prophets had done. It may be added that his miracles were done in a short time. They were constant, rapid, continued, in all places. Wherever he was, he showed that he had this power, and in the short space of three years and a half it is probable that he wrought more miracles than are recorded of Moses and Elijah, and all the prophets put together.
