Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the middle of a people of unclean lips…
Students of religious biography are familiar with the strange tale of the great mediaeval preacher, Dr. John Tauler, of Strasburg, and know how popular he was while sermons were of the letter only, and not from the Spirit, and how he was set to the child's task of learning the very A B C of Christianity ere he could preach with the tongue of fire which reaches the hearts and consciences of the hearers. Falling into great weakness of body and continual sorrow of soul, losing all trust in himself and his own doings, he owned with bitter tears, "I am wretched and miserable and poor and blind and naked." It was at that moment he received the blessed knowledge of Christ as the sin offering, and the Spirit of the Lord used him thenceforth in a marvellous manner for the convicting and comforting of the citizens, in the midst of earthquakes and wars and famine and pestilence, so that the great power of God fell upon that town as probably never before nor since.
