In Daniel 12:1 it says at that time shall Michael stand up, or take a stand. In Revelation 12:7 Michael fights the dragon.
When did or will Michael take a stand? It has to happen after the book of Daniel was written, right? And Michael has to take a stand to fight the dragon, right?
I don't know how you are reading Daniel 12:1 but you at least need to be reading it like such, since no one begins a new sentence, such as---and at that time--unless there is previous context that explains at what time. Then you have to ask yourself when reading it like the following, is it still fitting your theories.
Daniel 11:40 And at the time of the end shall the king of the south push at him: and the king of the north shall come against him like a whirlwind, with chariots, and with horsemen, and with many ships; and he shall enter into the countries, and shall overflow and pass over.
41 He shall enter also into the glorious land, and many countries shall be overthrown: but these shall escape out of his hand, even Edom, and Moab, and the chief of the children of Ammon.
42 He shall stretch forth his hand also upon the countries: and the land of Egypt shall not escape.
43 But he shall have power over the treasures of gold and of silver, and over all the precious things of Egypt: and the Libyans and the Ethiopians shall be at his steps.
44 But tidings out of the east and out of the north shall trouble him: therefore he shall go forth with great fury to destroy, and utterly to make away many.
45 And he shall plant the tabernacles of his palace between the seas in the glorious holy mountain; yet he shall come to his end, and none shall help him.
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.
2 And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.
To prove my point. What if I simply said this. Are you going to specifically know when I'm meaning?
And at that time Joe will get in his car and drive home.
Rather than this instead.
At the end of Joe's shift that day, Joe will then clock out. Walk out in the parking lot. And at that time Joe will get in his car and drive home.
