This article begins by surveying the decline of churches in Europe today. It makes the point that if the Church loses its life of dynamic vitality it is bound to fall even if it has a long history, good tradition and profound theology. If the church is determined to recover the power of the gospel and to save the world, it is vital for theological institutions to equip students with the balance in theology, discipleship and practice. Regrettably most theological institutions focus on teaching theology as merely an academic discipline. They pay little attention to equipping students as the disciples of Christ whose hearts are filled with passion and commitment. Their training does not offer students practical tools that they can use in their fields of ministry. It is the case particularly among the theological institutions in Europe, which regard theology as “the queen of science”. As a result the church in Europe has experienced a rapid decline, and Europe, which used to be the main force for mission, has now become a serious mission field. It is because reformed theology, which originated in Europe, lacks life in its theology. The Apostle Paul is the father of Reformed Life Theology. He was a model who planted life-giving churches and pastored them by keeping the balance with theology, discipleship and practice. The churches and theological institutions today need to take his example seriously. Paul expressed his theology by both explaining the truth of the gospel and defending it. The core of his gospel was Jesus Christ, his suffering on the cross and resurrection. He was a committed disciple of Christ who had firm and passionate conviction in the gospel. Furthermore, he was a Christian who put into practice the truth of the gospel in daily life. Amnos Church Planting School, UK, is introduced towards the end of this article, as a case institution which applies the Pauline principles in training church planters and pastors. The ethos of Reformed Life Theology, that is to revitalize the Church with the life of the gospel, needs to spread to the world.
