Epictetus, Golden Sayings 58

Even as the traveler asks his way of him that he meets, inclined in no way to bear to the right rather than to the left (for he desires only the way leading where he would go), so should we come unto God as to a guide, even as we use our eyes without admonishing them to show us some things rather than others, but content to receive the images of such things as they present to us. 

But as it is we stand anxiously watching the victim, and with the voice of supplication call upon the augur: "Master, have mercy on me; vouchsafe unto me a way of escape!"
