To reduce the depression a individual is experiencing, it is important to understand the specific causes of that person's depression. Although it may have many different causes, some Christians teach simplistic models of depression, such as saying that all depression comes from unconfessed sin or lack of faith. Such teaching is inaccurate and produces further condemnation rather than help for hurting people.
Some depression does come from spiritual sources.
David experienced depression when he realized that Bathsheba was pregnant, and when he later learned that the child conceived with her would die. Whenever we knowingly commit sin, we are likely to experience guilt feelings and depression. The only truly effective remedy for this kind of depression is confession, repentance and, when appropriate, restitution. Another type of spiritual depression is called anomie . Anomie refers to the aimlessness and despair that comes when one lacks a sense of purpose or significance in life.
