I just wanted to add some more comments to my 3/23 post TO CHANCE & FAY: THE ABOMINATION OF DESOLATION IN 'THE HOLY PLACE' IN THE TEMPLE in regards to your comment ""And I believe the Third Temple with the altar of God and the arc of the covenant comes down from Heaven in the New Jerusalem.  This Temple is not built by human hands this time."

The book of Revelation doesn't say anything about the Temple of God in heaven with its altar and the ark of the covenant seen in Rev. 11:19 coming down from heaven in New Jerusalem. Rev. 21:22 says, "And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it."

In my opinion, there has to be a third temple built because 2 Thess. 2:3-4 says that "the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God."  Also Matthew 24:15-16, Mark13:14, Daniel 11:31 &  Daniel 12:11 show the abomination of desolation either being set up or standing in 'the holy place' which was always inside the temple.  

Then there also will be a 4th temple with its worship system & offerings described in Ezekiel chapters 40-48 which is the Millenium temple during the Lord Jesus' 1,000 year reign on Earth. I believe the Lord Jesus will build the Millenium temple with the help of others because Zechariah 6:12,13 & 15 says," And speak unto him, saying, Thus speaketh the LORD of hosts, saying, Behold the man whose name is The BRANCH; and he shall grow up out of his place, and he shall build the temple of the LORD: Even he shall build the temple of the LORD; and he shall bear the glory, and shall sit and rule upon his throne; and he shall be a priest upon his throne: and the counsel of peace shall be between them both. And they that are far off shall come and build in the temple of the LORD, and ye shall know that the LORD of hosts hath sent me unto you. And this shall come to pass, if ye will diligently obey the voice of the LORD your God."  I could be wrong but I believe the Branch is the Messiah, the Lord Jesus Christ.  Here is an article about it at https://christholdfast.org/prophecies-in-the-bible/the-branch-building-the-temple-zechariah-612-13/

Then we see New Jerusalem coming down from heaven that has no temple therein: for the Lord God and the Lamb are the temple of it (Rev. 21:22)

I also agree with you and Fay that there are only 1,260 days or 42 months to the great tribulation period described in the book of Revelation, and not a 7 year period.
