Jesus tells us that to become a Christian, there has to be a smashing. Christianity is new wine: it ferments, it swells, it’s organically and chemically active, and it will smash the old, inflexible wineskins.
Jesus teaches that there’s an old way that everybody, religious or not, operates under. You will not be a Christian until all your old foundations, your whole approach to yourself and God, are utterly smashed. You must be called away from mere religion.
What’s the difference between religion and Christianity? In Matthew 9, we see 1) what religion is, 2) how Jesus smashes it, and 3) a few tests by which we can judge whether we’ve moved away from religion.
