John Piper said this quote
“ I am wired by nature to love the same toys that the world loves. I start to fit in. I start to love what others love. I start to call earth home. Before you know it, I am calling luxeries needs and using my money just the way unbelievers do. I begin to forget the war. I don't think much about people perishing. Missions and unreached people drop out of my mind. I stop dreaming about the triumphs of grace. I sink into a secular mind-set that looks first to what man can do, not what God can do. It is a terrible sickness. And I thank God for those who have forced me again and again toward a wartime mind-set. ”
