Can any of you, for all his worrying, add one single cubit to the span of his life? And why worry about clothing? Think of the flowers growing in the fields: they never toil nor spin; yet I assure you that not even Solomon in all his regalia was not arrayed like one of these. (Matt. 6:24-34)
Of course it is maddening to be told not to worry. Worrying is innate to our nature. Yet as the priest told us at mass – you can try to live for the moment and stop awhile to look at nature and concentrate on it.
