Sanctification is an essential part of every Christian life. But how do its differing theologies shape our Christian walk and wider socio-ethic contexts? Grounded in the East Africa Revival Movement (EARM), this work seeks to answer how the Keswick theology of sanctification contributes to the socio-ethical understanding of "walking in the light" and consequently influences the mission of the Anglican Church in the Mount Kenya region. Dr. Robinson Kariuki Mwangi uses careful exegetical analysis to understand the biblical roots of revival and calls us to action in showing what our faith stands for, integrating practical theology with pastoral practice. Scholars of theology and lived Christianity will find the observations in this work informative for further study.
