One might appropriately wonder how the Atonement can be effective in the lives of mortals. Even though we seek to be worthy and to repent of our sins, in the end we are all, in one way or another, unprofitable servants (see Mosiah 2:21). Given our weakness and our recurring failings, how are we able to receive the many blessings of the Atonement in our lives? How are we able to receive of its cleansing powers, or peace, or succor, or freedom? How does the perfection and exaltation of an imperfect being come about?
