Acts chapter 20 tells how Paul sat down to train the elders of the Ephesian church he had planted some years before. The principles of gospel ministry he lays down are simple, but absolute dynamite. In 21 simple, practical principles, Richard Coekin sets out how this 'Gospel DNA' should shape our approach to building churches today. This book draws on his experience as Director of the London-based Co-Mission church-planting initiative London, UK. It will help you be part of a dynamic strategy for growing gospel churches today. Includes a Foreword by D.A. Carson
