Norman Geisler, along with Ronald Brooks, shows how Christians can greatly improve their thinking skills. 'To Learn the rules of clear and correct thinking, ' the authors maintain, 'is more than an academic exercise. For the Christian, it is also a means of spiritual service' since 'the principles of good reason flow from God's very nature.'
