Against Calvinism is best read in tandem with Michael Horton's book For Calvinism. As a stand alone volume, it is a pointed and carefully argued answer to the Calvinist viewpoint, and helps the reader to understand the theological problems that come with Calvin's presentation of God, grace, foreknowledge, and predestination. Olson also presents an alternative viewpoint, Arminianism, that approaches God's sovereignty and the will in a different way without neglecting the biblical witness. This is a good book, especially for those seeking a better understanding of Calvinism and its critics.
