Dangerously Pure

At church today, at one point a little clip was played. It was taken from some kind of prophetic word that was originally posted on a prayer wall in the middle east. Someone copied it from there and brought it back to the US, where it's been made into skits and songs and all kinds of stuff like that. It even remained anonymous for a long time before the author finally came forward.

Anyway, during that pice we were listening to, a little phrase popped out and struck me. Dangerously Pure. I really like that, and yet....what does it mean? How can purity be dangerous? To what is it dangerous? Is it kind of like the metaphor about light versus darkness, and light cutting through the darkness, and the darkness can't stand it or stand against it? Can purity be such a powerful force that, for instance, me being so pure that it infects people I'm around? Purity, in it's truest sense, is not weak. We Christians are not trying to "protect" our purity in the sense that it's fragile and if we move the wrong way it will break. But can it be aggressive to the point of being dangerous? Interesting to think about, I think.
