No it isn't. You let some idiot plant that idea in your mind.
That Ezekiel 43 Chapter is a type of rebuke from God specific to the ten tribed "house of Israel" about their having fallen away from Him in the past, and now He tells them to 'measure' the Ezekiel temple as a way to express their past shame. The following verses proves God is speaking to them regarding when that temple will be built after Christ's return...
Ezek 43:7
7 And He said unto me, Son of man, the place of Hy throne, and the place of the soles of Hy feet, where I will dwell in the midst of the children of Israel for ever, and Hy holy name, shall the house of Israel no more defile, neither they, nor their kings, by their whoredom, nor by the carcases of their kings in their high places.
KJV
God said that to Ezekiel after... giving the measurements of Ezekiel's temple. He says the "house of Israel" (ten lost tribes) shall no more defile His holy name by what they had done. That means AT THAT POINT the "house of Israel" do not sin against The LORD anymore, so when would that be? Once Jesus returns.
This idea is continued into the next Ezekiel 44 Chapter also...
Ezek 44:6-16
6 And thou shalt say to the rebellious, even to the house of Israel, Thus saith the Lord GOD; O ye house of Israel, let it suffice you of all your abominations,
7 In that ye have brought into My sanctuary strangers, uncircumcised in heart, and uncircumcised in flesh, to be in My sanctuary, to pollute it, even My house, when ye offer My bread, the fat and the blood, and they have broken My covenant because of all your abominations.
8 And ye have not kept the charge of Mine holy things: but ye have set keepers of My charge in My sanctuary for yourselves.
That is what the children of Israel did in the past. They allowed bondservants of the Canaanite nations to become servants in the 2nd temple in Jerusalem when they were not supposed to be near the Altar.
9 Thus saith the Lord GOD; No stranger, uncircumcised in heart, nor uncircumcised in flesh, shall enter into My sanctuary, of any stranger that is among the children of Israel.
But in the future temple, the Ezekiel temple God gave the new measurements to, it will be built when Jesus returns, and God purges the sins of Jacob. Then none of the Canaanites will be allowed in that Millennial "sanctuary".
10 And the Levites that are gone away far from Me, when Israel went astray, which went astray away from Me after their idols; they shall even bear their iniquity.
11 Yet they shall be ministers in My sanctuary, having charge at the gates of the house, and ministering to the house: they shall slay the burnt offering and the sacrifice for the people, and they shall stand before them to minister unto them.
12 Because they ministered unto them before their idols, and caused the house of Israel to fall into iniquity; therefore have I lifted up Mine hand against them, saith the Lord GOD, and they shall bear their iniquity.
13 And they shall not come near unto Me, to do the office of a priest unto Me, nor to come near to any of My holy things, in the most holy place: but they shall bear their shame, and their abominations which they have committed.
14 But I will make them keepers of the charge of the house, for all the service thereof, and for all that shall be done therein.
Those Levite priests who went astray when Israel fell to idol worship will still be given charge of God's 'house', and its service, but not allowed to approach Christ at His table to serve Him.
15 But the priests the Levites, the sons of Zadok, that kept the charge of My sanctuary when the children of Israel went astray from Me, they shall come near to Me to minister unto Me, and they shall stand before Me to offer unto Me the fat and the blood, saith the Lord GOD:
16 They shall enter into My sanctuary, and they shall come near to My table, to minister unto Me, and they shall keep My charge.
KJV
But these Levites, the sons of Zadok, which is put for The Just (meaning of Zadok), represent the faithful elect of Christ's Church. Only they will be allowed to approach Jesus in that future Millennial time to serve Him at His table.
Thus the TIMELINE of all this is still FUTURE for AFTER Jesus has returned, and is reigning IN JERUSALEM ON EARTH over all peoples and nations. The last 8 Chapters of the Book of Ezekiel are all future Millennial Chapters.
