I agree with Jay Homnick when he states, below, that Pat Robertson, as a spritual leader and ordained minister, has a right to make claims about what God's will might or might not be.
However, I also believe that rights bring responsbilities. Given the necessary ambiguity of any spritual dimension behind secular events, it is incumbent upon leaders such as Pat Robertson to be highly careful and circumspect in the public claims they make about God's intentions in "managing" worldly affairs. In addition, given that evangelical churches have a less rigid structure than older denominations, it is particularly tempting for evangelicals to make such statements. God's will is such a serious matter, however, that one should be reluctant to say in public some things that one might well think and say in private, given that the incorrect attribution of motives to God could in itself be a serious offense against that very God.
This is something to which Robertson seems regularly to give far too little consideration.
