should we fall, we should not despair and so estrange ourselves from the Lord’s love. For if He so chooses, He can deal mercifully with our weakness. Only we should not cut ourselves off from Him or feel oppressed when constrained by His commandments, nor should we lose heart when we fall short of our goal…let us always be ready to make a new start. If you fall, rise up. If you fall again, rise up again. Only do not abandon your Physician, lest you be condemned as worse than a suicide because of your despair. Wait on Him, and He will be merciful, either reforming you, or sending you trials, or through some other provision of which you are ignorant.
–Saint Peter of Damascus (d. 750)
