Forgiveness is the greatest gift you can give yourself and others. "Atonement and forgiveness are the supreme expressions of human freedom - the freedom to act differently in the future than one did in the past," (Rabbi Jonathon Sacks z'tzl) To be able to change and begin again. Hashem allows us to this by not only forgiving but forgetting and even erasing our past sins. Hashem believes in our ability to remake ourselves and return to Him in humility and love. It is an illusion when we think Hashem no longer wants us because of our sins. Hashem does not leave us when we sin, it is we who lose contact with Hashem who resides within the essence of our own soul.
