why

I have begun to tell more and more people about my pending move to Africa. Because of this I find myself answering the WHY question. Now, not everyone asks it outright, though some do and it is easier to address that way, but I can tell that nearly every thinks something like it. And because "why not?" doesn't seem to be a good answer I'm processing. I suspect this will be an ongoing topic for a little while.
So:
Why am I getting rid of my house, quitting my job and moving to a place where clean drinking water is precious?

God told me to.

I may need to work on this answer a little more....
