Jim Elliot had a great quote:
He is no fool, who gives what he cannot keep, to gain what he cannot lose.
Allan Harman's biography of Matthew Henry quotes his father Philip Henry with much the same words:
He is no fool who parts with that which he cannot keep, when he is sure to be recompensed with that which he cannot lose.
–from Matthew Henry: His Life and Influence, by Allan Harman, (Chritian Focus, 2012), Kindle location 345-47.
It would be remarkable if Elliott were not echoing Henry. Neither men were fools. They lived by these words. What about you?
