The Red Heifer... Check out:

There have been some red heifers in the past, but they turned out to be flawed by a single white hair or something else. Our non-believing Orthodox Jewish brothers and sisters await a flawless Kosher red Heifer to sacrifice for the ashes that they will put in their mikvahs for the priest to go down into so they will be ceremonially clean.
Then they can go up on the Temple mount and commence the laying of the cornerstone for the third Temple (Ezekiel's Temple) and the building of the altar for the daily sacrifices. This will consitute the beginning of said third Temple and that officially to the Orthodox Jews brings in the Messianic Era....
Now for us what does this mean? ....
The covenant that is confirmed by many for 7 years will also be making way for this Temple to be built. This begins the last seven years before Yahushua (Jesus) returns! I estimate that we are within five years of this all commencing and the anti-annointed one (anti-christ) taking his seat in the rebuilt Temple and declaring himself to be Elohim (god). What exciting times we are living in!
The mayhem before he comes back will go something like this....
The Temple begins and Israel welcomes a Messiah (the false one). 3 1/2 years will pass and then the abomination that makes the Temple desolate happens (from Daniel and Revelation) and then the last 3 1/2 years of the 7 year period is the time called the "Great Tribulation".
Yahushua said there will not have been such great tribulation ever seen upon this earth before. It is my personal belief that during this time non-Torah observant Christianity will be suffering greatly and not knowing why.
Then after the tribulation of those days (Matt. 24:29) the sign of Yahushua's coming will appear. He'll come down and ressurect those who are dead in Him and then we will be changed in a moment.
From there I guess it's off to the battle of Armageddon? and then the marriage supper of the lamb that many thing regular Christians may not be able to be a part of because their garments are spotted because of saying the Torah (Law of Moses) was nailed to the cross and they didn't have to obey it. Truly, Yahushua said not one Jot or Tittle shall pass from the Law till all things be fulfilled. It won't be too much longer and all things will be fulfilled. wooooowhoooo!
