Do not lose heart, O soul, do not grieve; pronounce not over thyself a final judgment for the multitude of thy sins; do not commit thyself to fire; do not say: The Lord has cast me from His face. Such words are not pleasing to God. Can it be that he who has fallen cannot get up? Can it be that he who has turned away cannot turn back again? Does thou not hear how kind the Father is to the prodigal? Do not be ashamed to turn back and say boldly: I will arise and go to my Father. Arise and go! He will accept thee and will not reproach thee, but rather rejoice at thy return. He awaits thee; just do not be ashamed and do not hide from the face of God as did Adam.
