Idolatry…includes anything on which we set our affections and indulge as an excessive and sinful attachment… Idolatry includes anything we worship: the lust for pleasure, respect, love, power, control, or freedom from pain. Furthermore, the problem is not outside of us, located in a liquor store or on the Internet; the problem is within us. Alcohol and drugs are essentially satisfiers of deeper idols. The problem is not with the idolatrous substance; it is the false worship of the heart.
