By the time we came to NA, our inner voices had become unreliable and self-destructive. Addiction had warped our desires, our interests, our sense of what was best for ourselves. That's why it's been so important in recovery to develop our belief in a Power greater than ourselves, something that could provide saner, more reliable guidance than our own. We've begun learning how to rely on this Power's care and to trust the inner direction it provides us.
As with all learning processes, it takes practice to "pray only for knowledge of God's will for us and the power to carry that out." The selfish, ego-driven attitudes we developed in our addiction are not cast off overnight. Those attitudes may affect the way we pray. We may even find ourselves praying something like, "Relieve me of this character defect so I can look good."
The more straightforward we are about our own ideas and desires, the easier it will be to distinguish between our own will and our Higher Power's will. "Just for your information, God" we might pray, "here's what I want in this situation. Nonetheless, I ask that your will, not mine, be done." Once we do this, we are prepared to recognize and accept our Higher Power's guidance.
