I'm worried christians today may be worrying needlessly about things they have no real control over. Also some may be entering territory they were never meant to broach. The book of Daniel and the book of Ezekiel are difficult enough to delve into without touching on Revelations. I'm mightily worried that the warning finishing up the book, is a clue that people already have altered things. And considering the admonishment Jesus gave us about worrying about what even tomorrow might bring, you know , we have enough to worry about the troubles of today, never mind the heaviness of worrying about the long term portents contained in such books of prophecy. Some of us have been called to look into such things and have been shown things pertaining to the end. If these things are not self evident to you , fret not, for you are valued by God , who is the true Judge, more than many sparrows. And if all the hairs on your head are numbered, and rest assured they are, then He will certainly be making sure you know all you need to know.
Shalom to all my brothers and sisters, and may God bless all of you in perpetuity.
