David F. Wells in The Courage to be Protestant:
The point I am making is quite offensive to us today. It is that God hides himself from us, that he cannot be had on our terms, and that he cannot be accessed from “below” through natural revelation. In the malls, and in much of life, we encounter nothing like this. We expect access. We expect to be able to get what we want, when we want it, and on our terms.
Here this is not the case. Here we have to be admitted to God’s presence, on his terms, in his way … or not at all. We cannot simply walk into his presence. Here nature does not itself yield grace. God’s grace comes from the outside, not the inside, from above and not from within. It is not natural to fallen human life. We enter the presence of God as those who have been estranged, not as those who have been in continuity with the sacred simply because we are human. We are brought into a saving relationship through Christ; we do not put this together from within ourselves.
