Theology & Evangelism by J.I. Packer

"Evangelism and theology for the most part go separate ways, and the result is great loss for both. When theology is not held on course by the demands of evangelistic communcation, it grows abstract and speculative, wayward in method, theoretical in interest and irresponsible in stance. When evangelism is not fertilized, fed and controlled by theology, it becomes a stylized performance seeking its effect through manipulative skills rather than the power of vision and the force of truth. Both theology and evangelism are then, in one important sense, unreal, false to their own God-given nature; for all true theology has an evangelistic thrust, and all true evangelism is theology in action." - J.I. Packer
