From the date of this visit, the best energies of Martin's life were devoted to improving the lot of the prisoners in Great Yarmouth Gaol. She did not—indeed, she could not—give up her dressmaking. She worked out at her customers' houses, earning about 1s. 3d. a day. Her first resolve was to give up always one day a week to her prison work, and as many other days as she could spare. She began teaching the prisoners to read and write; she also read to them, and told them stories. A deeply religious woman herself, it pained her that there were no services of any kind in the prison, and she prevailed upon the prisoners to gather together on Sunday mornings and read to one another. To encourage them in this she attended herself, not at first as the conductor of the service, but as a fellow-worshipper. This was very typical of her method and character. She was among them as one who served, not as one seeking power and authority. Another illustration of this sweet humility in her character may be given. She wished those of her pupils who could read to learn each day a few Bible texts; and she always learned some herself, and said them with the prisoners. Sometimes an objection was made. In her own words, "Many said at first, 'It would be of no use,' and my reply was, 'It is of use to me, and why should it not be so to you? You have not tried it, but I have.'" There was a simplicity in this, a complete absence of the "Depart from me, for I am holier than thou," which was irresistible, and always silenced excuse.
Soon after the commencement of the Sunday services in the prison, it was found necessary, through the difficulty of finding a reader, that Sarah Martin herself should conduct the service. At first she used to read a sermon from a book, but later she wrote her own sermons, and later still she was able to preach without writing beforehand. According to the testimony of Captain Williams, the Inspector of Prisons for the district, the whole service was in a high degree reverent and impressive. The prisoners listened with deep attention to the clear, melodious voice of their self-appointed pastor.
