The nature of Leithart’s theological commentary varies. At times he is connecting the passage to redemptive history (as with the introduction, noted previously). Other times he demonstrates how a passage sheds light on a theological issue (e.g., a discussion about the rightness of prophetic declarations of judgment concludes with a reflection on the justice of eternal punishment in Hell). Most often, Leithart identifies various typological connections between Scripture texts. Some of these typologies are probably legitimate (i.e., though I don’t see a Moses-Elijah typology as Leithart does, I do think that the text presents parallels between Moses and Elijah for the purpose of demonstrating that even the great prophet Elijah is not the Prophet like Moses that the people are to anticipate),in many cases the parallels are more dependent on Leithart’s imagination and clever phasing than on the text (e.g., taking the three year drought during Ahab’s reign to foreshadow the three days that Christ, “the true Israel,” was in the tomb ).
So while I enjoyed Leithart’s introduction (especially after having a read a number of non-evangelicals on theological interpretation), I’m not inclined to actually buy this volume.
