We should repent of our sins while we are still on earth. When a potter is making a vessel and it becomes misshapen or breaks in his hands, he shapes it again; but once placed in the oven, it is beyond repair. Now the clay in the craftsman’s hands is an image of ourselves, and it teaches us that, while still in this world, we must wholeheartedly repent of sins committed in the body and make it possible for the Lord to save us while there is time. When we have left this world, we shall no longer be able to repent and confess our sins. We must do the will of the Father, keep our bodies pure, and observe the commandments of the Lord, for this is the way to obtain eternal life… While we can still be healed, let us surrender ourselves into the hands of our divine physician and give him his recompense, the recompense of true sorrow for our sins. Since he who knows all things sees what is in our hearts, let us praise him with our hearts as well as our lips. He will then receive us.
