What was the key detail of the God-breathed interpretation given by the prophet Daniel to Babylonian king Nebuchadnezzar about the fourth kingdom represented in his vision? In Daniel 2 the interpretation regarding the first the world empire, that of Nebuchadnezzar's Babylon, in contained in all of two verses (37 and 38). The next two subsequent world empires (Medo-Persia and Greece) each share one-half of the single verse within Daniel 2:39. But then from Daniel 2:40-43 the interpretive attributes of the fourth empire are given some very good detail which denotes the importance of this empire as the world's last empire. The key God-breathed detail here is that the two legs of iron resolve themselves to a pair of feet each containing ten individual toes. Those ten toes, the essential elements or nations of the Roman Empire, exist to this day.
In Daniel 7:7-8; 23-27 even more detail is given about the fourth beast in a God-breathed vision Daniel received just prior to the fall of Babylon to the Medo-Persian Empire. These two sets of verses in Daniel 7 say absolutely nothing about the fourth beast falling only to be revived again. This beast is continuous throughout time, from its first appearance in ancient history where it supplanted the Greek third beast to its destruction in the future by Jesus Christ at the conclusion of the 70th Week.
In Daniel 8:23-26 where the angel Gabriel is providing an even more detailed interpretation of his vision regarding of the Greek conquest of the Persian Empire, once again there is the central theme of continuity from those ancient times to the present and future times of the 70th Week. I would advise the reader to continue reading the Book of Daniel, chapters 9 through 12 as the unrelenting prophetic narrative is continued to the conclusion.
Revelation 13 is the basis of the interpretive artistic imagery seen above. It is also the God-breathed reiteration of all that was revealed to the prophet Daniel through earlier visions and Gabriel's interpretations.
"There is no other worldwide Gentile kingdom in scripture between the time of the ancient Roman Empire and the time that the latter-day prince makes a seven-year covenant with Israel at the end of the Gentile age (Dan 9:27). Therefore, in God’s eyes we must still exist in the era of the Roman fourth beast that is recorded in the book of Daniel (Dan 2:40, 7)."
So, Rome never fell, and there is no "revival of the Roman Empire" that we need to see occur prior to the 70th Week. The fourth world empire is here now and it is a global power: economically, politically and militarily. And consider this if you're interested in looking for a definitive sign of the last days. Daniel 11:21 contains a detailed precursory view of the coming Antichrist and his sudden rise to global power. That precursor was manifest in the person of Antiochus IV Epiphanes, the supreme ruler of the Hellenic (Greek) Seleucid Empire. The man who will be the Antichrist leading the already existent fourth world empire will be one of the leaders of an existing Western nation who will suddenly, and by intrigue or the aid of a few of the elite of the peer leadership around him, take full control of the already existing reigns of power of the already existing political structure, exactly as Antiochus IV Epiphanes did with the Seleucid Empire in the Daniel 11:21 template of 2,189 years ago. That man could very well be any one of the men seen standing in front of national flags and symbols in a lineup of Western leaders at any of the numerous summits or peace negotiations seen on the evening news. He just hasn't been revealed yet.
