The way in which we pray, when we pray really and simply, not saying prayers composed by others unless they are truly the expression of our own faith, but with simplicity talking to God in absolute confidence and sincerity, tell what our faith is.
The point of passing time in solitude is to strip yourself bare, to discover what is essential and true. When you are stripped down to this point, you see how little you amount to. But that little is what God is interested in.
