Daniel 10-12: The End of Days

In the third year of Cyrus king of Persia, a revelation was given to Daniel (who was called Belteshazzar). Its message was true and it concerned a great war. The understanding of the message came to him in a vision. - Dan. 10:1 NIV

Daniel had seen a lot in his lifetime.  He was taken into Babylon as a captive while Nebuchadnezzar was king.  He saw Nebuchadnezzar's son, Belshazzar die and Babylon taken over by the Persians.  He has been under the reign of various Persian rulers, Xerxes, Darius, who threw him to the lions, and Cyrus. He has seen kingdoms come and go, so his understanding of what the angel told him about events to come may be different from ours.  Daniel may have understood that there are kingdoms of this earth and kingdoms that are not of this earth...the principalities and powers that are mentioned in Ephesians 6:12

For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.

There is only so much that can be revealed to us, and very little that we can comprehend.  But, the promise to Daniel remains true.  There will be a time of distress such as has not happened from the beginning of nations until then. But at that time your people—everyone whose name is found written in the book—will be delivered. Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt. Those who are wise will shine like the brightness of the heavens, and those who lead many to righteousness, like the stars for ever and ever. - Dan. 12:1-3 NIV
 
Even Daniel did not understand what he had been told.  I heard, but I did not understand. So I asked, "My lord, what will the outcome of all this be?"
He replied, "Go your way, Daniel, because the words are closed up and sealed until the time of the end...."As for you, go your way till the end. You will rest, and then at the end of the days you will rise to receive your allotted inheritance." - Dan. 12:8-13 NIV

At the end of the days, we will receive our allotted inheritance.  That should be all we need to know to live our lives in the here and now.
