“Go ye therefore and teach all nations… Teaching them to observe all things whatsoever I have commanded you… (Matthew 28: 19a, 20a)” is the Great Commission of Jesus Christ. Jesus, in his ministry, taught his followers the Word of God and mandated them to continue to teach all nations, peoples and tongues. Today, Christian believers gather weekly for public worship. There is singing, praying, musical renditions, reading of the scriptures, rites and sacraments and the preaching of the Word. Unfortunately, most teaching ministries including the weekly Bible Studies attract little interest resulting in small attendances. Busy schedules, inadequate preparation, and misguided focus are but some of the reasons why our Churches are failing to fulfil the instructions of Jesus to teach. This book, “Just One Hour,” is a prayerful, thoughtful, systematic, teaching tool that would inspire all believers to go deeper into God’s word. The wide range of topics covered are important for evangelism, discipleship, pastoral care, family life and social action. It is a book that can be used by the believer at home for personal and family study as well as for leaders of small or large Bible Study groups.
