Exaggerated repentance is a reverse form of pride. We are designed to acknowledge our imbalances, adjust for them and MOVE ON. Accepting forgiveness in every moment in which it is required, letting go of yesterday's failures, we move forward in healing... Our processes of healing will show us failures; we must see where we are going before we can adjust the course. However, the healing process does not define us! It is just the manner in which we awaken. It is vital to recognize the false pride of the sinner for what it is: a cop-out, an escape mechanism through which the fearful avoid responsibility -- and, as they eventually find out, salvation.
Ultimately we have just one moral duty: to reclaim large areas of peace in ourselves, more and more peace, and to reflect it toward others. And the more peace there is in us, the more peace there will be in our troubled world.
