Don't Waste Your Life

I may have posted this before, but it bears repeating. I love this quote from John Piper's book, Don't Waste Your Life:

"You don't have to know a lot of things for your life to make a lasting difference in the world. But you do have to know a few great things that matter, perhaps just one, and then be willing to live for them and die for them. People who make a durable difference in the world are not the people who have mastered many things, but who have been mastered by one great thing. If you want your life to count, if you want the ripple effect of the pebbles you drop to become waves that reach the ends of the earth and roll on into eternity, you don't have to have a high I.Q. You don't have to have good looks or riches or come from a fine family or a fine school. Instead, you have to know a few great, majestic, unchanging, obvious, simple, glorious things- or one great all-embracing thing- and be set on fire by them."
