So [God] says this, 'Pray inwardly, even though you feel no joy in it. For it does good, though you feel nothing, see nothing, yes, even though you think you cannot pray. For when you are dry and empty, sick and weak, your prayers please me, though there be little enough to please you. All believing prayer is precious in my sight.' God accepts the good-will and work of his servants, no matter how we feel.
--St. Julian of Norwich
