"Pleas, tears, arguments, or threats will not penetrate. Reason is useless. We cannot simply say, 'Stop doing drugs, get control of yourself, stop worshipping an idol.' As a result of spiritual oppression, drug worshippers may be very intelligent, but they can be oblivious to the destruction and slavery associated with drug abuse. They need the power of God (1 Cor. 1:18), the message of Christ crucified and risen. Other therapies can offer sobriety, but only this good news is powerful enough to liberate the soul."
