Topic

Evangelical missiology today represents a diverse collection of ministry activities that often are not grounded in confessional Protestant theology and, in some instances, stretched far beyond the bounds of biblical theology. Conversely, many churches in the Reformed tradition have a solid biblical foundation, but often their mission practice falls far short of the historical examples found in the early church and the many missionary movements that followed. The solution for both is to again build our missiology and evangelistic practice on the biblical foundation of Triune doctrine and biblical theology.
