We are all too aware of the damage poisons can have on our bodies. These ailments find their way into us, invading us, infecting us, and spreading throughout us until the illness is felt all over. There are spiritual poisons that work this way as well, except these ailments invade another kind of body-the spiritual body of Christ. Like the diseases of our physical bodies, these diseases slow the body down, crippling it to function at less than capacity. They limit what the body can do and the effectiveness it can have. If not treated, these diseases can lead to death. Why Churches Die looks at the body's diseases and reflects on the corresponding spiritual ailment. Mac Brunson and Ergun Caner practice the science of spiritual forensics to prevent churches from unnecessary illness and premature death.
