Monergism

"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 communication, 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

"Evangelism that does not lead to purity of life and purity of doctrine is just as faulty and incomplete as an orthodoxy which does not lead to a concern for, and communication with, the lost."
Francis Schaeffer

"One question frequently stops Christians in their tracks: "If the Gospel alone saves, then what about the heathen in Africa who never heard?" Can God justly convict a man who hasn't heard about Jesus? Some people hear the Gospel and reject it, but most never hear it. How can God condemn them? Christians are ill-equipped to respond because they don't really understand something vital about sin and mercy. Sin brings guilt. Mercy is a gift. Anyone who is a sinner receives punishment he deserves. Anyone who is saved receives mercy he does not deserve and which is not owed him. Think of this question: How could the sheriff send anyone to jail if he didn't offer him a pardon first? The answer is simple. If he's guilty, the sheriff is justified in throwing him in jail. There is no obligation to offer a pardon to a guilty man. The same is true of God. He can justly convict a man who has broken His law even though the sinner has heard nothing about God's pardon in Jesus. God owes no one salvation. He can offer it to whomever He wishes. That's why it's called grace."
Gregory Koukl
