All final spiritual reference is to be the silence beyond sound. The word made flesh is the first sound. Beyond that sound is the transcendent unknown, the unknowable. It can be spoken of as the great silence, or as the void, or as the transcendent absolute.
In all our activities we may be seeking God: in our work, on our social occasions, as we walk along the road, even when we are so busy that we have not time to think of anything except what we are doing... God can deal with us under a thousand forms for our spiritual hallowing. Behind all the strange puzzles of life there is the secret working of God, creating life, creating character, accepting service -- all sorts of spiritual shaping going on.
