Agency is simply the ability to do good. There is nothing negative about it. Everyone has choice, even the adversary, for he choses how to carry out his plans. He and his followers put themselves in a position where they cannot, and will not do anything good. Agency is a fruit of the atonement, guarded and again granted unto us because of our faithfulness in our first estate. Now, we must use our agency to act righteously, and not be acted upon, thus successfully fulfilling our second estate.
