While I agree with the concern expressed in #1 I strongly caution anyone from adopting a position that conducting intercessory prayer for a city or a nation is worthless.
I have seen it work.
That being said I am against a "dominionist" position that is based on some word of faith heresy.
However, I have seen to much in the Spirit realm to throw all supernatural intervention by God under a heading of "witchcraft"
