Helpful primer on depression, stressing the heart and its idol-making propensities as the root cause. Welch admits there may be physical and/or chemical issues involved as well, and these are worth investigating, but the major problem with depression is a vertical one -- the individual sufferer's relationship to God (or lack thereof). Some very helpful, concrete, actions that can be taken to combat this insidious issue, as well as suggestions that have assisted other sufferers, conclude this short booklet. Great resource! ( )
