“We should give thanks to Him, as it is said: ‘In everything give thanks’ (I Thess. 5:18). Closely linked to this phrase is another of St. Paul’s injunctions: ‘Pray without ceasing’ (I Thess. 5:17), that is, be mindful of God at all times, in all places, and in every circumstance. For no matter what you do, you should keep in mind the Creator of all things.”
(St Peter Damascene, ‘The Philokalia’)
