There are many different kinds of prayer. Yet all prayer has one basic purpose. We pray not to get something, but to open up a two-way street between us and God so that we (and others) may inwardly become something beautiful that we share with others.
It is the nature of a word to reveal what is hidden. The word that is hidden still sparkles in the darkness and whispers in the silence. It entices us to pursue it, to yearn and sigh after it. For it wishes to reveal to us something about God.
