When the heart is warm and full the lips become eloquent. Jesus expects each of His followers to testify for Him. His redeemed ones should need little persuasion to plead His cause. Every genuine conversion creates a new advocate for His side. Dumbness is one of the signs of unreality in religion. The sin of silence received due castigation, in public and in private, from the tongues of fire which the Spirit gave to William and Catherine Booth. Their children therefore learned that it is every Christian’s calling to speak in season and out of season for Christ, to press His claims upon the willing and the unwilling alike. Katie, it appears, began among her little companions in the Victoria Park. Her old nurse still remembers how she would gather little groups about her and tell them of the Saviour’s love. When she was in her twelfth year, she lived for some time with a family in Clifton, along with whom she attended the Church of England. One Sunday evening the Vicar, who had noticed her earnest gaze fixed on his face, sent for her that he might have a little talk with her. He asked her what she liked best in the Bible, and she answered "The Atonement." He was so struck by her intelligence that he offered her a children’s class, which soon grew large. Week by week she talked to the little ones of sin and the Saviour. Letting story-books go, she went for their conversion. Having to return home on her twelfth birthday—the last day on which she could travel with a half-ticket—she told her mother of her great longing to continue her work among children. Her mother readily consented, and soon there was a weekly gathering of young folk in a downstairs room of the Gore Road house. After a while Katie had the assistance of her sister Emma, who was her junior by little more than a year. Tears were shed, confessions made, and lives changed in that room. And there two of the most brilliant evangelists of our time first learned to deal with souls. They were in every way kindred spirits. Long afterwards one finds Emma writing to Catherine: "We will always be ’special sisters.’ We were Ma’s two first girls, and were brought up side by side—and side by side we will labour and love till we stand with our children in her presence again before the Throne!"
