" 'Dr. Culver is a veteran teacher in the classic evangelical and Reformed stream of Christian understanding, and this wide-ranging, well-directed, sharp-sighted textbook, the fruit of decades of reading, thinking, and classroom encounters, is his magnum opus ... All must admire his thoroughness in thinking through the main questions, fudging none and always proposing answers that stimulate, even when they do not finally convince. Within the group of recent conservative systematic theologies this one stands high as a demonstration of the biblical rationality of the Reformed faith. --J. I. Packer"
