Packer on Evangelism

...Forcing tactics can only do damage, perhaps incalculable damage, to men's souls... Evangelism must rather be conceived as a long-term enterprise of patient teaching and instruction, in which God's servants seek simply to be faithful in delivering the gospel message and applying it to human lives, and leave it to God's Spirit to draw men to faith through this message in his own way and at his own speed...

...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...
