God as personality is not a physical reality that everyone must see whether they want to or not. He can, of course, make himself present to the human mind in any way he chooses. But—for good reasons rooted deeply in the nature of the person and of personal relationships—his preferred way is to speak, to communicate: thus the absolute centrality of scripture to our discipleship. And this, among other things, is the reason why an extensive use of solitude and silence is so basic for growth of the human spirit, for they form an appropriate context for listening and speaking to God.
