Guilt is a function of conscience; guilt is defined as consciousness of interrupted spiritual communion, or consciousness of lowering of one’s moral ideals (103:4.3). Conscience is a function of mind which delineates between right and wrong on a human level. Guilt is the feeling that the conscience provides to indicate to us that something wrong has been thought or done. Guilt is a result of a failure in resolving issues of right and wrong. The two go together: conscience and guilt. A person without guilt is a person without a conscience, and a person without a conscience is called a psychopath.
I think it’s important to stress that guilt is not synonymous with punishment. Guilt is simply a feeling of wrongdoing or wrong thinking, both of which interrupt spiritual communion and fall short of one’s moral ideals. It’s a feeling of moving in the wrong direction. Responding to that feeling and choosing to correct it is all it takes to erase guilt for that particular episode. But to erase all guilt forever is just not possible unless one is perfect in every way and never makes any mistakes in thought, word or deed. I don’t know any human being alive that fits into that category.
When Jesus said the following:
156:2.7 “My disciples must not only cease to do evil but learn to do well; you must not only be cleansed from all conscious sin, but you must refuse to harbor even the feelings of guilt. If you confess your sins, they are forgiven; therefore must you maintain a conscience void of offense.”
He instructed us not to harbor feelings of guilt. He did not say to never, ever have guilt. To harbor guilt means to hold onto one’s mistakes secretly, to bring the guilt ship into port and shelter the negativity in your mind so it eats away at you as a form of punishment. He is saying that he does not want us to become overly self-critical but to forgive ourselves; or rather, allow God to forgive us and get on with it. The important part of the quote is to maintain a “conscience void of offense,” which means to recognize and correct wrong doing and wrong thinking in order to maintain uninterrupted spiritual communion, knowing that God only requires a resumption of loyal relations with him without punishment by him or yourself.
