I see this way that God constantly goes to metaphors. And Jesus does too in the parables, expecially when talking about the kingdom of heaven. Metaphors are limited in complete understanding and inherently wrong when taken to (theological) extremes.
Even the notion of God as Father has led me to absolutely declare that God is a man....
I wonder how much of our faith, and our understanding of God, comes in metaphors. How much of God's revelation of himself is purposefully given in ways that keep us from making absolute statements and going to extremes that will make us look silly 500 years from now or sooner...I think this may be truer than may of us may be comfortable with.
Further, by using metaphors that are inherently flawed at extremes, does God keep us from knowing absolutely? Does this help keep our faith from being knowledge? hmm...
