I came across this during a Google search:

One of the primary tasks of any prayer is ‘How do I let God be God? How do I empty my mind and heart – not so as to confront a kind of void, but so that the personal presence of God can come in?’

If all prayer is trying to listen to God we have to remember that the God that we are seeking to meet is a person, and we come into a personal presence. And that means of course, that praying is about a great deal more than words in the same way that personal presence is about a great deal more than words. The Word of God – the way God communicates – is by being God, by being himself; so one of the primary tasks of any kind of prayer is ‘How do I let God be God?’ ‘How do I empty my mind and heart, not so as to confront a kind of void but so that the personal presence of God can come in? And words are part of that but only a very small part.
