In Prayer, Does Purity of Intention Matter?

A man of true faith has no reason to call upon the name of God.  His heart is One with God; why would he cry out to Him?  He can better worship by sitting in silence.

And so the intensity of my prayers is a measure of my cowardice.  And if our God is a Gnostic God, like the God of the Old Testament, He reacts to such prayers with resentment and even spite.  Perhaps this is what Jim Morrison of the Doors meant when he said, insistently, that "you cannot petition the Lord with prayer."
