In the Gospel of John we read the marvelous story of the man blind from birth to whom Jesus gave sight. When questioned by leaders of the Jews who sought to discredit the miracle and its author, the man said: “Now we know that God heareth not sinners: but if any man be a worshipper of God, and doeth his will, him he heareth.Since the world began was it not heard that any man opened the eyes of one that was born blind.
If this man were not of God, he could do nothing.” Unable to respond to the argument, the questioners angrily assaulted the character of the formerly blind man, who now saw with much greater clarity than did they. (See John 9:31-34.)
It is an eternal principle that the powers of heaven are inseparably connected with righteousness (D&C 121:36). The working of miracles in the name of Jesus is an evidence that one is “cleansed every whit from his iniquity” and thus worthy of the companionship of the Holy Ghost and the powers of God. The wonders of God- the signs and miracles which always attend a dispensation of the gospel- require righteousness in the human instrument (see D&C 50:27-30).
