the very minute we think we 'have' God, God will surprise us. As we search in fire and earthquakes, God will be in the still small voice. As we listen in silent meditation, God will be shouting protests in the street. God is warning us that we had best not try to find our security in any well-defined concept or category of what is Godly - for the minute we believe we are into God, God is off again and calling us forth into some unknown place.
