I thought this was a thoughtful quote from another book, found on the STR blog:
From A God Entranced Vision of All Things by Donald S. Whitney:
In contrast to Edwards's example, most people seem to lean one way or the other, favoring devotion or doctrine, piety or theology. But strong piety will not excuse us from the study of theology, nor will a strong theology compensate for a lack of piety. Edwards models the fact that a real understanding of the truth of God will set the heart on fire, and that the heart set on fire by God will burn with a love for learning his truth. As it was with Edwards, sometimes the things of God should appear so beautiful to our minds that we can't help but study and meditate on them and so ravish our hearts that we want to weep or sing (p. 128).
