The language we use reflects and in turn shapes the way we construct our experience of the world. (Plaskow acknowledges that)...all of these images of God are humanly crafted metaphors, but our metaphors emerge out of specific cultural and political context. When these contexts change, the old metaphors must change with them.
The spiritual function of fierce terrain (in the apophatic tradition) is to bring us to the end of ourselves, to the abandonment of language and the relinquishment of ego. A vast expanse of jagged stone, desert sand, and towering thunderheads has a way of challenging all the mental constructs in which we are tempted to take comfort and pride, thinking we have captured the divine. The things that ignore us save us in the end.
