The word theology is often construed by many as referring to a very dry and academic discipline only reserved for the professional clergy and seminary professors. Many lay Christians in the church are intimidated by the subject and feel it to be a tedious intellectual exercise that is of no use for their spiritual growth and mission of the church. In an attempt to address this concern, Mark Kim presents here an introductory systematic theology that deals with the core doctrinal topics of Christianity that is accessible for the average layperson. The work will engage heavily with Scripture and the voices of the past and present who have contributed to the total theological voice of the church at large.In this second edition of the work, there is included an extra chapter on the doctrine of the Christian life. As pointed out in the first edition of the work, theology should foremost be practical in its results and application. The author addresses this concern by including a new chapter discussing the nature of the Christian life and how Christians should live in the world.
