The world is not going to glorify Christ because they see that Christians are wealthy and healthy and prosperous. Very simple reason why: that’s what they live for. So you use Jesus to get it. They use other means to get it. They’re not impressed. Jesus is the ticket. When the show starts, you throw the ticket away. They don’t need your ticket. They’re not impressed. I’m saying what I’m saying because I want them to be impressed. They’re not impressed with us prosperous, wealthy, safe, middle-class, do-what-everybody-else-does-people. Don’t build a church like that!
