You have taken a Scripture completely out of context to make up your doctrine. Do you really believe that there was (or will be) any cleansing required of anything in Heaven, which is where God's throne is? Where purity and perfection reigns?
That Scripture you quoted applies to the desecration of the future temple at Jerusalem by the Antichrist and its subsequent cleansing.
KJV Hebrews 8:1-5
1 Now of the things which we have spoken this is the sum: We have such an high priest, who is set on the right hand of the throne of the Majesty in the heavens;
2 A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man.
3 For every high priest is ordained to offer gifts and sacrifices: wherefore it is of necessity that this man have somewhat also to offer.
4 For if he were on earth, he should not be a priest, seeing that there are priests that offer gifts according to the law:
5 Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount.
Here is revealed the sanctuary of the new covenant. The sanctuary of the first covenant was pitched by man, built by Moses; this is pitched by the Lord, not by man. In that sanctuary the earthly priests performed their service; in this, Christ, our great High Priest, ministers at God's right hand. One sanctuary was on earth, the other is in heaven. The feast of, the Day of Atonement, which was celebrated once a year at the end of the Jewish calendar, involved the cleansing of the record of sin within the sanctuary. That record was painted in the blood of the Lamb.
There are books in heaven, where the records of our lives are written. The Day of Atonement in the typical sanctuary will find is antitype in the cleansing on the record of the sins of God's people at the end of time, followed by the High Priest leaving the sanctuary to return to earth for His people. The earth will at that time be devastated by fire and destruction from the plagues and the resulting global catastrophic release of poisons and nuclear fall out and widespread destruction, then shall be the releasing of the scapegoat, Satan, who shall then pay for the evil he has caused, the killing and the strife he instigated through his temptations and deceptions, released into the wilderness of this barren devastated earth for the following 1000 years while the saints are engaged in heaven with the judging of angels and preparing for the descent of the new Jerusalem into the earth, the destruction of the wicked, and the creation of the new heaven and the new earth. It isn't about Israel. It's about the church. It's about Jesus. There aren't two gospels... One for Israel and one for the church. There aren't two brides. Israel, and the church. And there is no blasphemous so called "God's temple" to be rebuilt. There may be a temple rebuilt. There may even be sacrifices and priests going about pretending to be following God, and there may be Christians all over the world celebrating this and denying Christ in doing so. But this will never ever be the temple referred to in Thessalonians. That Temple Paul speaks of in which the man
KJV 2 Thessalonians 2:4
4 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.
can only be the church.
