John Chrysostom

Nothing brings so much pain to the spirit as anxiety and cark. That He says, The morrow shall he anxious for itself, comes of desire to make more plain what He speaks; to that end employing a prosopopeia of time, after the practice of many in speaking to the rude populace; to impress them the more, He brings in the day itself complaining of its too heavy cares. Has not every day a burden enough of its own, in its own cares? why then do you add to them by laying on those that belong to another day?
