A certain man in Germany had committed a great sin, and was ashamed to confess it, yet on the other hand he could not endure the remorse which he felt, and went to cast himself into the river; but just as he was on the point of doing so, he stopped, and bursting into tears, prayed God to pardon him without confession. One night in his sleep he felt someone waking him, and heard a voice saying: "Go and make your confession." He went to the church, but yet did not make his confession.
He heard the same voice a second night; again he went to the church, but after he had entered it, said that he would rather die than confess that sin. He was about to return home, when he thought he would go and recommend himself to the most holy Mary, before her image which was in the church. He had hardly kneeled before it, when he felt himself entirely changed. He immediately arose, called for a confessor, and weeping bitterly, through grace received from the Virgin, made a sincere confession; and he afterwards said that he felt greater satisfaction than if he had gained all the gold in the world.
