Matthew 20:33

That our eyes may be opened - He who feels his own sore, and the plague of his heart, has no great need of a prompter in prayer. A hungry man can easily ask bread; he has no need to go to a book to get expressions to state his wants in; his hunger tells him he wants food, and he tells this to the person from whom he expects relief. Helps to devotion, in all ordinary cases, may be of great use; in extraordinary cases they can be of little importance; the afflicted heart alone can tell its own sorrows, with appropriate pleadings.
