“In 1815 Napoleon was defeated in the battle of Waterloo, and the hero of that battle was the Duke of Wellington. The duke’s most recent biographer claims to have an advantage over all the other previous biographers. His advantage was that he had found an old account ledger that showed how the duke had spent his money: that, says the biographer, was a far better clue to what the duke thought was really important than reading his letters or his speeches. Can you imagine that? If someone wrote your biography on the basis of your checkbook or your income-tax return, what might it say about you, your loyalties, your focus, and about whom you serve?” Heidi Husted, “The Sermon on the Amount,” Preaching Today.
