Affirming both the immanence and transcendence of God affects the meaning of transcendence. It becomes something other than the spatial imaginings of my youth, when I thought God was elsewhere, out there and not here. Rather, the transcendence of God refers to the mystery and ineffability of the sacred, to God as surpassingly more and surpassingly other than the world of our ordinary experience, even as God is also immanent and sometimes experienced. God is the "beyond in our midst," as the German theologian and martyr Dietrich Bonhoeffer put it in the last year of his life in a Nazi prison cell.
