How convenient, NTX. Why only those two choices? How about this. You answer this question.
Do you believe that President Bush is more of an instrument of God than King David was? The very same King David that refrained from killing King Saul even though David knew that he was to be the next King? How much easier did David have it than Pres. Bush? I mean he was right on top of an undefended Saul. George W. had to invade with his army. If David and Saul had been alive now, I'm sure Saul would be dead with the justification that God had delivered him into his hands. Don't you think?
Only two choices because they are the only two possible answers to my questions. Either God can/will, (if He chooses) to use humans to depose evil rulers, or God won't. I made no reference to GW and the war on Iraq. I have no idea if the U.S. was an instrument of God in this war. But I do believe that God can/will at times use one government as "His instrument" against another. Is it possible that the U.S. was used as an instruement of God? Sure it is. Whether or not that is the case in this instance is up for debate. But don't automatically say that it was not the case, Because truthfully, while on earth, we'll never know.
As to the comparision to GW and King David. "more of and instrument" is an interesting phrase when you think about it. I guess and instrument of God is an instrument of God, period. Pharoh was an instrument of God to his own destruction.
