Jews in Israel are now claiming that they are re-building thee 3rd Jewish Temple. This is a huge isssue, since many Biblical scholars and theologians believe that God is going to re-establish His Old Covenant sacrifices when the re-building of the so-called 3rd Jewish temple in Jerusalem is complete.
Many pre-milliennial theologians employ 2 Thessalonians 2: 2-12 to proclaim that antichrist will do this? But the problem is that this re-establishment of old covenant sacrifices is based upon one interpretation of Daniel 9, which claims that Daniel was prophesying that at the end of days, antichrist will set up and image of himself in the new temple at Jerusalem and will briefly put an end to sacrifices which have been re-established by a levitical priesthood.
However, despite the controversy which surrounds escatological interpretations, it is clear that Daniel 9 is a prophesy concerning the coming of Christ, who, according to many modern scholars, put an end to sacrifice and offering in the middle of the Jewish week and not Friday, as many claim to be the day in which Christ was crucified. However, the problem remains that the building of a 3rd temple in Jerusalem is not a mere matter of theological interpretation of the scriptures, or problematic only because the levitical priesthood does not exist anymore and cannot be reinstated by any priesthood, but, it is a problem regarding the Red Heifer.
According to the Bible, the Red Heifer was a bull used by levitical priests in accordance with the Law of Moses as part of the ritual sacrifices for the so-called cleansing of sin. These requirments are found in Numbers 19: 1-22, which is contained in the Bible and in the Torah and cannot be broken by anyone accept God Himself. So the problem remains, that there is no longer a pure Red Heifer anymore. The Red Heifer genetically gained white markings sometime over the last 2000 years or more. The white markings now found on the Red Heifer make it impossble for the laws of purification to be fulfilled according to the word of God. Jewish scholars and pre-millennial theologians have got a problem. Nothing other than a pure Red Heifer at the age of 3 can be a satisfactory offering (Genesis 15: 9)
So until a pure Red Heifer comes along, there is no signal for the end of days and the sooner people realise that the re-building of temple was made complete in the followers of the Lord Jesus, who are the Temple of the Holy Spirit, then the better for all of us.
