Since you're taking that kind of approach, trying to bring other ideas like 1 Sam.2:22 'into' the Ezek.44 Scripture, I guess I'm forced to cover it line upon line.
Ezek 44:4-24
4 Then brought he me the way of the north gate before the house: and I looked, and, behold, the glory of the LORD filled the house of the LORD: and I fell upon my face.
5 And the LORD said unto me, Son of man, mark well, and behold with thine eyes, and hear with thine ears all that I say unto thee concerning all the ordinances of the house of the LORD, and all the laws thereof; and mark well the entering in of the house, with every going forth of the sanctuary.
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.
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.
One of the very first things Israel did with disobeying God, was not destroying the nations of Canaan for their abominations which God had judged them for, and instead allowed them to creep into Israel stay. Israel eventually allowed some of them to become temple servants and even priests later. That was under the Old Covenant history, which only the sons of Levi and Aaron were supposed to have charge in God's house, including the cutting of wood for the altar.
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.
That means those are going to be under Christ's 'rod' of iron during that time. That's in accord with what Paul taught at the end of Rom.11 about all Israel being saved. Doesn't mean they are destroyed; means those of Israel that fell away are under the rod of discipline, yet still preserved. Those duties are about the 'bull work' of duties of the house.
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.
Who all does that apply to? The "house of Israel" is put for only the ten lost tribes after Solomon's days. That means the Christian Church. So those include the pastors and elders in Christ's Church today THAT... fall away and lead their Churches astray. Just because we're in a New Covenant era doesn't mean this doesn't apply to Christ's Church today. These will include the fallen leaders in Christ's Church represent the five foolish virgins that Jesus will tell them to get away from Him in that time. That applies to the leaders of orthodox Jews also who had fallen away and misled the other part of Israel known as "the house of Judah" after Solomon's days.
But here... are Christ's elect that reign with 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.
The word "Zadok" means 'Righteous'. Christ Jesus is King of Righteousness, and His elect servants are the Righteous, the Just. These are those five wise virgins who did not fall away.
Okay... I can buy that... but let's get the full revelation of what it is actually
referring to in the 44th chapter. Let's understand what Judgment God has
applied to these rebellious leaders. Also, let's understand that God takes the
credit for blinding the rest of creation, not just the Israelites. Romans 8:20,
20 For the creation was subjected to futility, not
willingly, but because of Him who subjected it,
in hope.
Let's see what Dr. Jones has to say about Ezekiel 44.
Although Ezekiel 44 uses the story of Eli and Zadok as the backdrop for the
prophecy, it is really about a New Testament priesthood in the Age of
Tabernacles that is soon to come. In the past 2,000 years there has been a
Christian priesthood under Pentecost--the leavened feast--that became as
corrupt as the priesthood of Eli. Many of them, though they steal offerings
and have sex with the women parishoners, do have a genuine belief in Jesus
Christ. In the age of the Prince of Peace, they will be allowed to minister in
the outer court (that is, the physical body). But they will not be allowed to
minister to God in His Sanctuary in heaven. In other words, they will not
receive that glorified body that can go back and forth between heaven and
earth--the kind of body that Jesus had after His resurrection.
Ezekiel describes this body in 44:17-19, putting it in Old Testament terms,
but prophesying of New Testament things:
17 And it shall be that when they enter at the gates
of the inner court, they shall be clothed with LINEN
GARMENTS; and WOOL shall not be upon them while
they are ministering in the gates of the inner court
and in the house."
Linen is made from plants; wool is an animal product. Rev. 19:8 says, "fine
linen is the righteousness [i.e., ZADOK] of the saints." Linen represents the
spiritual body, even as wool represents the fleshly, physical body.
And so, when these "priests of God and of Christ" are given glorified bodies,
like Jesus had, they will be able to go back and forth between heaven and
earth, ministering to God in Sanctuary in their "linens" and then returning
to earth dressed in "wool" to minister to the people in the outer court (end
quote).
My point is... these priest were blind, as you say, just as the creation was
subjected to futility... not by their own will, but by the will of God. Correct
me if I'm wrong, but the creation is in the same blindness the the priest
are in. God's judgment on the priest is losing their birthright and they will
be unable to minister to God. But most of the creation that is in futility will
spend eternity in hell or will be anniliated because God is a Holy God and a
just God. I ask you in humility... what is holy and just in this situation?
I see none! When God takes creation out of futility... all will become Sons of
the Living God. Just as God controls the devil by locking him up in the Age
to come and releasing him for His Will to be done, He has an appointed time
when He will release all from the bondage of corruption into the glorious
freedom of the children of God (Romans 8:21).
Can you lose your salvation?
According to Ezekiel 44... the answer is NO! The only thing you will lose is your
reward! There is a difference (1st Corinthians 3:15).
What a God! What a Plan!
Logabe
Here's one of their duties at that future time:
Ezek.44:23 And they shall teach My people the difference between the holy and profane, and cause them to discern between the unclean and the clean.
24 And in controversy they shall stand in judgment; and they shall judge it according to My judgments: and they shall keep My laws and My statutes in all Mine assemblies; and they shall hallow My sabbaths.
(KJV)
The ones who will 'stand in judgment' are the people they will be teaching. Teaching is one of the duties of the priest per the OT. This directly relates to what Jesus told the Church of Philadelphia in Rev.3 that He will make those of the synagogue of Satan to come worship at His elect's feet.
But outside... the gates of the holy city, is the outer darkness Jesus taught about...
Rev 22:14-15
14 Blessed are they that do His commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
15 For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
(KJV)
Now ALL of that above Scripture timing is for Christ's "thousand years" reign of Rev.20 ONLY.
After that "thousand years", Satan is loosed one final time to tempt the nations, and lead upon that "beloved city" on earth, then Satan and his host are destroyed. Then God's Great White Throne Judgment of those, and anyone's name found in the book of life are joined with Christ's elect. There will be many that will turn to Christ Jesus and be saved then after they've understood with their blindness removed. All those who still... refuse Christ Jesus will go into the "lake of fire" and perish, consumed.
