Here in this verse it is confirmed that Jesus was a true Messenger of God, with several signs and miracles:
* That he could make a bird out of clay and blow life in it, with the permission of God.
* That he could heal and give vision to born blind, and leper by the leave of God; An act, which in the sight of the physicians of his time, was undeniable great miracles.
* That he could report of the secrets of the people as to what had they eaten or hidden in their houses. All these were signs for them if they were believers.
this verse certifies that the prophets are able; of course with the permission of God, and when necessary; to ignore physics, and adhere to metaphysics, performing supernatural things!
