More fear mongering. When I see Christians whether of the right or left running around with bombs strapped to their waists I'll start to worry. In the meantime, if the Christians help to prevent the excesses of "feel good liberalism" becoming part of Australian society they'll be doing all a favour.
Jim Wallis is like a Bob Brown or Gough Whitlam that happens to have an evangelical clothing (or so he claims). The only concrete difference between Wallis and Whitlam would be porn would not be legal, no gay rights, abortions would not be legalized, and absolutely no humour in his speeches LOL. Leftists who dress as Christians are notoriously PC-minded like the Canadian do-gooders - the type that Australian electorates hate the most.
As a Christian I can see my fellow bretherns are divided. Some believe the Bible teaches feel-good liberalism (and indeed I was taught this is the biblical view when I was a boy), while most others think free market is more Christian (Acton Institute, Concerned Women for America, John MacArthur, etc). Welfare will destroy rather than help the needy, and mushy pacifism is national suicide.
I have confidence that Australian Christians won't be deceived by Wallis and put the ALP Left into power - although I can't say I have much confidence among the Christians from ethnic minority backgrounds.
