This book provides significant insights into the historical and theological development of classical Pentecostalism in the process of contextualisation in the Malaysian sociocultural and multifaith context. It is a systematic and comprehensive investigation into how the Assemblies of God Malaysia progresses from a classical Pentecostal movement towards the new identity of a 'Contemporary Pentecostal Church Movement', and the way forward for missions and Pentecostal spirituality in this twentyfirst century.
