Cornelius Van Tils Introduction to Systematic Theology is one of his two or three most important books, certainly a must-read for anyone who is trying to understand Van Til. And it is important for Christians to understand Van Til today, as never before. He challenges Christians to think in a distinctively biblical way. That biblical way opposes and challenges all religions and secular philosophies, all ideologies that place the ultimate source of truth and value in human beings rather than in God. As with the recently republished Christian Apologetics, P&R has thoroughly re-edited Van Tils syllabus, with an excellent introduction by William Edgar.
