I love this quote from Eugene Peterson's The Jesus Way:
"Following Jesus is a unique way of life. It is like nothing else. There is nothing and no one comparable. Following Jesus gets us little or nothing of what we commonly think we need or want or hope for. Following Jesus accomplishes nothing on the world's agenda. Following Jesus takes us right out of this world's assumptions and goals to a place where a lever can be inserted that turns the world upside down and inside out. Following Jesus has everything to do with this world, but almost nothing in common with this world."
