Here's an idea to keep you honest:
Make a really close friend whose worldview is totally opposed to your own and who isn't afraid to say so, and with whom you aren't afraid to disagree either.
I don't know that it's possible to go out and intentionally do this, but I would just say that if you find yourself in this position, you might want to consider thanking God for it and learning from Him in it, instead of running away from it like I tried to do that time (and sometimes keep trying to do). Particularly if you have been intentional about finding people who do share your worldview and can make sure you're not running off the rails somewhere.
The Milk Guy's really good at calling my bluff. I don't get to start sounding all super-spiritual without having to think about what I'm saying, and if I really mean it, and if I even begin to live up to it. And every once in a while he'll come up with a zinger of a theological insight that will set me on my heels.
This week has, as I keep mentioning, been a little rough for me, and actually the weeks leading up to it haven't been exactly stress-free, either, as we at Starbucks scramble to get enough work hours to support ourselves, for example. This kind of scenario makes me grumpy and weepy and I start making up new rude words out of existing rude words and find, to my chagrin, that I am kind of delighted with them because they are clever, even if thoroughly inappropriate for a Christian. (The Milk Guy doesn't help with that so much, because he thinks they're clever, too, and has no such scruples.)
The thing about all that is that though it doesn't make me look--or feel--very good, I don't get to make excuses for myself, like I might if I were going to go to a prayer meeting that night and rehash the day in Evangelese to my friends. The Milk Guy sees my moods and reactions in all their un-glory, and there's no explaining away with him.
It's kind of a lot of pressure. And sometimes I feel like I'm making a complete hash of reflecting Christ to anybody, let alone him. (And . . . I probably am.) But he doesn't let me wallow in "I'm such a horrible Christian" mode either. Recently I said, "I feel like God's trying to communicate with you . . . but He sure could have picked a whole lot better representative . . ."
The Milk Guy paused (understandably, as I think about it), and then said, "Aren't you kind of making yourself out to be more powerful than God when you say that?"
Oh. Right. And so we keep talking. And so he challenges me and I appreciate that, and I remember from time to time that not only am I not the perfect representative of Christ on earth, but that I don't have to be--because, as the Milk Guy himself reminded me whether he meant to or not, God is God and He'll cause whatever transformations He sees fit. Including in me.
