The problem with a bounded-set approach to Christianity is not that it highlights the difference between Christians and non-Christians; it’s that it highlights the wrong differences, and encourages us to exaggerate and claim differences that don’t exist. For instance, Jesus had a lot to say about concern for the poor. But if we think that non-Christians are also concerned for the poor, we won’t focus on it much because it doesn’t highlight “how we are different.” – John Ortberg
Great quote don’t you think? If instead we focus on Jesus, centered-set style, then the key question becomes whether someone is oriented toward Jesus or away from him. We realize that God is in a much better position than we are to know who’s in and who’s out. We also realize that everyone has something to learn, that everyone has a next step to take, and we don’t have to make ourselves seem more different than we really are. It puts us in a better position to affirm our convictions constructively, irrespective of who agrees or disagrees with us.
