Prophet Statesmen, Ezra Taft Benson
In connection with the attack on the United States, the Lord told the Prophet Joseph Smith there would be an attempt to overthrow the country by destroying the Constitution. Joseph Smith predicted that the time would come when the Constitution would hang as it were by a thread, and at that time, ‘this people will step forth and save it from the threatened destruction.’ It is my conviction that the Elders of Israel, widely spread over the nation, will, at that crucial time, successfully rally the righteous of our country and provide the necessary balance of strength to save the institutions of Constitutional government. Now is the time to get ready.
