Being generous with God

In his novel, The Diary of a Country Priest, by Georges Bernanos, the hero brings his life to a close with this prayer:

"Dear God, I give all to You, willingly. But I don't know how to give, I just let You take. The best is to remain quiet. Because, though I may not know how to give, You know how to take. . . Yet I would have wished to be, once, just once, magnificently generous to You."
