John Webster on how Christian theology can be helpful:
…only by recalling itself to its proper calling, which is the praise of God by crafting concepts to turn the mind to the divine splendor. But deeply important as they are, concepts are only serviceable as the handmaids of spiritual apprehension. (from “Life in and of Himself,” in Engaging the Doctrine of God, ed. Bruce McCormack, p. 123)
This is a good example of why Kevin Vanhoozer has remarked that when theologians read for their own profit, they read Webster.
