"Only a mythological deity leaves traces of its presence. The God of Israel, even when performing the most astounding miracles, leaves no evidence of His presence. . . . In this fashion God, author of the universe, simultaneously bestows existence to the universe and covers His traces 'out of existence'."
Jose Faur, as quoted by David Burell, CSC, "Maimonides, Aquinas and Ghazali: distinguishing God from the world," Scottish journal of theology 61, no. 3 (2008): 271. Some qualifications are in order here, but there is an orthodox sense in which this is quite true. (Faur isn't denying the reality of divine action.)
