Abba Macarius was asked, “How should one pray?” The old man said, “There is no need at all to make long discourses; it is enough to stretch out one’s hands and say, ‘Lord, as you will, and as you know, have mercy.’ And if the conflict grows fiercer say, ‘Lord, help!’ He knows very well what we need and He shows us His mercy.”

[Abba Macarius the Egyptian, Apophthegmata Patrum]
