The root of both psychological and spiritual sickness is preoccupation with self. Ironically, the believer who is consumed with his own problems – even his own spiritual problems – to the exclusion of concern for other believers, suffers from a destructive self-centeredness that not only is the cause of, but is the supreme barrier to the solution of, his own problems. Usually such selfishness isolates him from the other believers, who if they were intimately involved in fellowship with him, would be regularly praying for his spiritual welfare.
