The process we all go through as we grow would be comical if it weren't so sad. We all hit these points where "we've arrived" whether they be theological, political, social or otherwise. We feel as though we have the "right" take on things.
Or, we might not.
Every theology (what we'll focus on) has its holes - and I don't mean areas where a proof text here or there "debunks" something. That's just foolish, no singular passage of scripture really "proves" anything one way or the other, it simply provides us with the information we think we need to interpret that individual piece of text. And even that is sometimes a long shot. None of them are without areas that can be easily dissected by someone with a good education. Sadly though, we too often get locked into our particular theology and rarely see the holes in it, or ignore them because we may lose our pastorate or have to let go of some hate if we really saw the holes...
I mean, if everyone is included and I believe that, then what right do I have to treat ANYONE as though they are anything but a child of God? When I don't, I've just poked another hole in my theology - at least for those watching. I poke holes in my own theology all the time. Any time I walk by someone begging and don't offer a hand or a dollar. Any time I judge someone by the color of their skin, the box they check on election day, or the decisions they've made in this life (i.e. regarding someone according to the flesh) I'm poking holes all over my theology.
Listen closely, because I think I know why people don't want what we (Christendom) has to offer.
