A Sunday school teacher, a Mr. Kimball, in 1858 led a Boston shoe clerk to give his life to Christ. The clerk, Dwight L. Moody, became an evangelist. In England in 1879, he awakened evangelistic zeal in the heart of Fredrick B. Meyer, pastor of a small church. F. B. Meyer, preaching to an American college campus, brought to Christ a student named J. Wilbur Chapman. Chapman, engaged in YMCA work, employed a former baseball player, Billy Sunday, to do evangelistic work. Billy Sunday held a revival in Charlotte, N.C. A group of local men were so enthusiastic afterward that they planned another evangelistic campaign, bringing Mordecai Hamm to town to preach. During Hamm’s revival, a young man named Billy Graham heard the gospel and yielded his life to Christ. Only eternity will reveal the tremendous impact of that one Sunday School teacher, Mr. Kimball, who invested his life in the lives of others.
