“Jesus is not against investment. He is against bad investment—namely, setting your heart on the comforts and securities that money can afford in this world. Money is to be invested for eternal yields in heaven: ‘Lay up for yourselves treasures in heaven!’”

—John Piper, Desiring God

“Whatever captures the heart’s trust and love also controls the feelings and behavior. What the heart most wants the mind finds reasonable, the emotions find valuable, and the will finds doable….What makes people into what they are is the order of their loves—what they love most, more, less, and least. That is more fundamental to who you are than even the beliefs to which you mentally subscribe. Your loves show what you actually believe in, not what you say you do. People, therefore, change not by merely changing their thinking but by changing what they love most. Such a shift requires nothing less than changing your thinking, but it entails much more.”—Tim Keller, Preaching
