Where, O Where Has Theology Gone?

In looking through Christianity Today's list of the most influential evangelical books of the last half century, one can't help but notice the dearth of substantive theology.  There are plenty of experiential biographies, lots of "practical" books for family life and church management, but almost nothing in theology.  The notable exceptions, of course, are Tozer, Piper, Stott, and in a way, Schaeffer.  We could perhaps include a title that certainly should have made the list: Jerry Bridges' The Pursuit of Holiness.  But where are all the books on the incarnation and the atonement? 

Too often, the previous generation of evangelicals assumed its theology rather than defended it, especially in more recent decades.  If history holds true, the coming generation will be the one that forgets the theology its fathers and mothers loosely accepted but did not inculcate.
