I've recently been rediscovering Jesus from a new perspective, having grown up with a typical American Christianity and abandoned it as a teenager.
I've been finding that a lot of people from all kinds of backgrounds see the Jesus story and "Christianity" from this other perspective, where his teachings are universal and very subversive as you describe, and quite unlike the christian religion that we see. I've started to see the "kingdom of God" Jesus talks about in all kinds of people from all backgrounds -- including atheists and people who are still in the christian religion, and in all other religions or non-religions. Basically, I'm learning that people are people, and that all people have something good at their core that can be nurtured and brought out.
I've found Jesus' teachings and example extremely compelling to what I think of as the "real" me inside. And it's actually radically changed my life in 2015, in terms of how I spend my time and how I react to the things that happen to me.
What if I really could love my neighbor as I love myself? (And genuinely love myself, to start with.) Then nothing could really harm me.
It's really exciting to see these ideas popping up all over the place in various forms. I no longer see there being one group that is "in" while all the rest are "out", but rather that all of us have bits of this "kingdom of God" in us regardless of what we call it, and it's good and can grow, and it doesn't actually matter what we call it. The point is that it always brings love, joy, peace, patience, kindness, goodness, generosity, gentleness, etc, which are universally good things that we all desire deep down.
