"Going up to Jerusalem", Twenty Sermons (1886), p. 330.
Context: O, do not pray for easy lives. Pray to be stronger men! Do not pray for tasks equal to your powers. Pray for powers equal to your tasks! Then the doing of your work shall be no miracle. But you shall be a miracle. Every day you shall wonder at yourself, at the richness of life which has come to you by the grace of God.

Reported in Van Wyck Brooks, New England: Indian Summer, 1865–1915 (1940), p. 418, footnote. Another source states: "The celebrated anecdote... is not so unambiguous as it appears... There is no reason to doubt the authenticity of Hale's reply, but it should be understood within a framework of respect for the senators as well as concern for the country. He knew every one of them personally and regarded them, as he said in his preface to Prayers in The Senate (1904), as 'intelligent men, in very close daily intimacy with each other, in the discharge of a common duty of the greatest importance.'"
