CLAIM: Jesus will show forth His power to save and lead every nation on earth.
False.
This is a good and valid prayer, may God do these things. The tone is supplicational and intercessory, and does not need to be regarded as a necessary to be fulfilled passage any more than a man in a prayer room praying, “God save Africa”. May God do it, we should all pray, but what will be the end of the matter is of the Heavens.
