This thesis analyses the conversion processes of 17 urban Muslims in Kenya who decided to follow Jesus Christ. It first describes conversion from a multidisciplinary perspective by introducing sociological, psychological, anthropological, theological and missiological understandings of such a change in religious affiliation. Next in-depth interviews are analysed using principles of grounded theory, where new theory is developed by interaction between data from reality, the analysis and existing theories (abductive reasoning). The main findings are that the conversion of Muslims who accept Jesus Christ as Saviour and Lord is a process that develops over a period of time through phases with a cognitive and an affective dimension. Changes with regard to convictions and attitudes take place simultaneously on several properties or ‘layers’ of both dimensions. The process is influenced by significant factors in the form of causal and intervening conditions, resulting in consequences for the convert in the form of a transformation as well as in changed relationships with the community. Gender, socio-economic level, education as well as the community from which the converts come influence the process. In order to describe the complex dynamics that are at work in such conversion processes of Muslims, a Matrix of Conversion Processes is developed in which the multiple movements of a convert on the two dimensions are put in relation to six chronological phases. A matrix of different types of conversion processes and the description of four typical processes emerge from the analysis. In order to facilitate conversion processes, cognitive and affective elements need to be addressed together. The interaction between different factors, the will-power of the person and the influence of God determine the development, an understanding that is relevant for conversion studies, as well as for missiology and the missionary task of the church in Kenya and beyond. / Christian Spirituality, Church History and Missiology / D.Th.
