Addiction is bondage to the rule of a substance, activity, or state of mind, which then becomes the center of life, defending itself from the truth so that even bad consequences don’t bring repentance, and leading to further estrangement from God. To locate it on the theological map, look under sin. More specifically, since sin is a broad category that includes both self-conscious disobedience and victimizing slavery, find addiction on the side that emphasizes slavery.
