Discipleship is less about finding the right path, and more about following the right person. Montgomery Ward is thought to be the first retailer to promise “Satisfaction Guaranteed or Your Money Back” after launching a successful mail-order business in 1872. His guarantee was revolutionary in building trust among customers accustomed to patronizing local stores in person. But you could argue that Jesus was the first to articulate the idea of “satisfaction guaranteed” long before it became standard consumer lingo.
