And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book." [Daniel 12:1]
Of course, Michael is the Archangel of God, and the specific National Guardian Angel of Israel. We see this responsibility in Dan. 10:13,21; and in 12:1, quoted above. To more fully understand the events about to break upon us, and the role that the conflict in the supernatural sphere will play in these events, let us examine several additional Scriptures.
1) Even though we cannot see the struggle occurring, supernatural beings are battling in their dimension, to determine the events about to occur on Earth.
In Daniel 10, we see that Daniel began a 21 day fast so that God would hear his prayer to tell him more of Israel's future. On the first day of Daniel's fast, God sent this angel to go to Daniel with the answer. However, this angel was prevented from getting through to Daniel because of a conflict with a demonic being described as "prince of the kingdom of Persia". What does this title mean? It means that Satan has assigned a powerful demon, who is identified here, to attempt to influence the activities of the King of Persia. The Bible does teach that both Demonic and Godly angels are assigned to the leaders of the nations throughout history, to influence the ruler to take actions that will direct his nation one way or the other. In the case of this angel trying to come to Daniel, he was unable to defeat this powerful National Angel on his own, so he had to turn to the National Angel for Israel, Michael, for assistance. Apparently, Michael is the most powerful of the national Godly Angels, for we see him gaining the victory over the demonic National Angel here, in Daniel 12:1, and in the Book of Revelation [12:7], where Satan himself is cast from Heaven by Michael.
The key point here, though, is to understand that each major nation, at the least, and maybe all nations, have had a supernatural angel assigned to the leader of the time. God assigns His angels, and Satan assigns his. Battles are constantly occurring in the Supernatural realm for the direction of that human national leader.
2) A description of a particular battle that occurred in the time of Daniel is given us, for our greater understanding.
Verses 12-13 and 20-21 describe a battle between Godly and demonic forces that sounds very intense and extremely protracted. Apparently, also, the battle for the direction of a particular country begins in the Heavenly sphere many years before that country or that leader actually arise. In verse 20-21, we see that, when the Godly Angel returns to the supernatural sphere, he knows he will be engaged in a battle for the King of Greece. The domination of the Grecian Empire was still over 200 years in the future at this time.
3) Events will get so very bad that Israel will be defeated were it not for the powerful intervention of Michael himself, the Guardian Angel of Israel.
At the time of the End, events will turn so completely against Israel that her powerful National Guardian Angel, Michael, will have to vigorously defend Israel. Let us examine these Scriptures, the first of which we printed, above.
Daniel 12:1 -- ""And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book."
* The words "At that time", refer to the Great Tribulation Period, spoken of in Daniel 11:36-45.
* In Biblical terminology, whenever a priest or a leader has to "stand up", it means that he is springing to action to defeat an enemy.
* We see that this crisis which causes Michael to "stand up" to defend Israel is totally unprecedented in nature. Israel is going through a period of trouble unequaled in her entire history, and this trouble occurs in the Last Days of Time.
* The strong implication here is that, if Michael did not personally defend Israel during this time of unequaled trouble, Israel would be annihilated.
