In The Twelve Steps and Twelve Traditions it is written: "A continuous look at our assets and liabilities, and a real desire to learn and grow by this means, are necessities for us. We alcoholics have learned this the hard way. More experienced people, of course, in all times and places have practiced unsparing self-survey and criticism. For the wise have always known that no one can make much of his life until self-searching becomes a regular habit, until he is able to ADMIT and ACCEPT what he finds, and until he patiently and persistently tries to correct what is wrong.
Through daily inventory we can admit and accept that our character defects are a part of our human nature, a part that cannot manifest if we are truly living in the will of God. We are completely capable of understanding, if the proper work on the 12 steps is thoroughly done, that our human nature is in fact defected. We must accept this about ourselves if we desire to be recovered.
In the program of Alcoholics Anonymous it is often said, "Let go and let God." The "Let go" part is turning from the incessant prompts of our human nature and the "Let God" part is living in, and thereby manifesting, the will of God. Living in the raw-natured will of God, our character defects cannot be manifested in our behavior - it is in such a spiritual place that our nature can be perfected as we become the human being that God created us to be.
Self-survey is a most powerful tool of recovery.
