Iron Skillet. That 'virus of faith' as you put it underpins nearly every aspect of the world you inhabit, and the life you live.

Incidentally, which country has tried to eradicate Christianity, but arguably has the fastest growing Christian church in the world? China. No power or principality shall prevail against the Lord. Might want to ponder that....as others have done for two thousand years.
