I don't want to be unclear about this; I, too, find "happy holidays" mildly annoying. But where's the sense of proportion? Just read through Hebrews chapter 11. If that doesn't sound like your recent life experience, it's probably time to smile more and whine less. You say that Christianity's disrespected in your child's government school? How surprising can that be? Maybe your kids shouldn't be there in the first place. Why this perpetual surprise that unbelievers persist in acting like unbelievers? The real scandal, it seems to me, is that we putative believers don't act more like believers. We say we're convinced that there is a real damnation from which we've been rescued, and that we stand on the brink of an eternity in which we'll be enjoying the pleasures and rewards carried in our Lord's hand ... and then we walk through this life wearing sour grimaces on our faces and chips on our shoulders, just daring the wicked world to treat us as well as we so clearly deserve to be treated. Amazingly enough, we're not very convincing to the world. Hmmm ... how can that be? How can those foolish worldly folk fail to want to share the joy that so obviously fills our lives?
Maybe we could spend more of our time loving and serving the people who are perishing all around us, and less time demanding their respect. I'd venture to guess that if we did, we might end up with a little credibility and respect anyway, even though (or maybe because) we weren't seeking it ... and a full measure of the joy of the Lord thrown in too. Worth a try, I think. Gotta work better than what we're doing now.
