This is a great book for understanding the foundations of a Reformed view of free will. I am not Reformed (at least not in terms of TULIP) I am Weslyan-Arminian in my soterology. That being said, Uncle Augie is about 90% compatible with that point of view. He certainly combats the hated Pelagian heresy well. I will try to give this theological classic the treatment it deserves, but for now let me just say that it is a book that Christians should think through even if we disagree on some of it in the end.
