For the addicted person alone, struggling only with willpower, the desire to continue the addiction will win. It will win because it resides, as we shall see, at the level of biological conditioning, and it is always operative. Willpower and resolutions come and go, but the addictive process never sleeps. The caring community around the person has more potential than this. Even though this community is bound to have its own mind tricks and mixed motivations, it has a chance for a better perspective. Most importantly, the people who care about a chemically addicted person have one another. Grace is always a present possibility for individuals, but its flow comes to fullness through community. Grace flows toward appreciating the truth, toward an accurate understanding of what is going on beneath the confused surface of addiction.
