In this revised and enlarged edition, Leander E. Keck presents a succinct, comprehensive, and up-to-date scholarly interpretation of Paul's theology. Keck has revised the volume to account more fully for Paul's understanding of the law and of faith/trust. He has retained the basic structure of the first edition but now apprises the reader of specific details of his own continuing thinking in light of select scholarly discussions. Entirely new to the volume is an appendix, Paul's Theology in Historical Criticism, a summary of the scholarly effort to account for, understand, and interpret Paul's theology.
