How do you overcome a guilty conscience and self condemnation? We cannot worship God as a corporate body unless we become one. And individually, you must become whole - body, soul and spirit.
Guilt is the result of a consciousness that you did wrong - whether real or imagined.
Whether you actually did it really or simply imagined that you did it, your conscience is violated. Imagination is reality.
A guilty conscience can lead to mental issues, including depression. Whether your active memory remembers the act, the conscience continues to be bruised.
