This book is an exposition of the significance of the Great Commission of Christ for Christian life and how it to be properly obeyed. It emphasises the sovereignty of God as Father, Son, and Holy Spirit, over this Commission and the rightful place of the Church as His People in its fulfilment. It addresses the biblical, theological, and ministerial, facets of the Commission. The core of this Commission is being disciples who make disciples for Christ by the Spirit and the Word of God. Obeying the Great Commission is not only the focal task of the Church but the way the Spirit transforms believers to be like Christ and grow towards His fullness. It exposes many misconceptions and misapplications that have seriously hampered the fulfilment of this commission and how to treat them. It shows the principles and the core processes that are required for its proper realisation.
