In 1973, while serving as Math Lecturer at The University of Lagos, W.F. Kumuyi started a Bible study group with 15 university students who had come to him requesting training in the Scriptures. By the early 1980’s that small group had grown to several thousand, at which time Deeper Life Bible Church was formally established.

By 1988 the congregation had grown to 50,000, and now numbers 120,000 members, making it the third largest Christian church in the world. Dr. Johan Combrinck reports that the Deeper Life Bible Church not only has an attendance of 120,000 every Sunday, but has planted 500 churches in Lagos, 5,000 in the rest of Nigeria (with an independent estimate of more than 800,000 members in Nigeria alone), and 3,000 elsewhere (with missionaries to 40 countries of Africa) as the movement missionary contribution.
