It is good…to pray always and not to lose heart, as the Lord says, And again the Apostle says, ‘Pray without ceasing’, (Lord Jesus Christ Have Mercy On Me) that is by night and by day and at every hour, and not only when coming into the church, and not bothering at other times. But whether you are working, lying down to sleep, traveling, eating, drinking, sitting at table, do not interrupt your prayer, for you do not know when he who demands your soul is coming (death approaching…). Don’t wait for Sunday or a feast day, or a different place, but, as the Prophet David says, ‘in every place of his dominion’.
Whether you are in church, or in your house, or in the country; whether you are guarding sheep, or constructing buildings, or present at drinking parties, do not stop praying. When you are able, bend your knees, when you cannot, make intercession in your mind, ‘at evening and at morning and at midday’. If prayer precedes your work and if, when you rise from your bed, your first movements are accompanied by prayer, sin can find no entrance to attack your soul.
Saint Maximos the Confessor
