Stringfellow is just full of good stuff. Still in Chapter Two of An Ethic for Christians an Other Aliens in a Strange Land, he says this about trying to understand God:

Biblical ethics do not pretend the social or political will of God; biblical politics do not implement “right” or “ultimate” answers. In this world, the judgment of God remains God’s own secret. … It is the inherent and redundant frustration of any pietistic social ethics that the ethical question is presented as a conundrum about the judgment of God in given circumstances. Human beings attempting to cope with that ethical question are certain to be dehumanized. The Bible does not pose any such riddles nor aspire to any such answers; instead, in biblical context, such queries are transposed, converted, rendered new. In the Bible, the ethical issue becomes simply: how can a person act humanly now? … Here the ethical question juxtaposes the witness of the holy nation - Jerusalem - to the other principalities, institutions and other nations - as to which Babylon is a parable. It asks: how can the Church of Jesus Christ celebrate human life in society now?
