Nah..., that's doctrines of men you are trying to use to replace what the Scripture actual says as written.
2 Peter 3:8-9
8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
9 The Lord is not slack concerning His promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
KJV
Peter actually is... pointing directly... to the literal "thousand years" period written of in Revelation 20 that begins at Christ's future return. The main subject of that 2 Peter 3 Chapter is about the 3 world earth ages. And with that 2 Peter 3:8-9 Scripture, Peter is letting us know that God is long-suffering and does not wish that any should perish, but that all should come to repentance, meaning believe on Him and His Son Jesus Christ unto Eternal Life. That is actually what the future literal "thousand years" reign by Christ and His elect over the UNSAVED NATIONS is about. There are many souls of this present world time that never had their opportunity to hear The Gospel and believe. That future "thousand years" period that begins at Christ's future return will correct that. And those of God's people that erred will be taught the difference between the holy and profane, and the clean vs. the unclean per God's laws. That is going to be one of the jobs of Christ's future priests, to teach.
And for the "dead" in that future time, for the sake of a relative, those in Christ as His priests, will be allowed to go to a SPIRITUALLY dead relative and help them, for in that time no one is literally dead in a literal grave anymore. The "dead" of Rev.20:5 represent the spiritually dead without Christ, the UNSAVED. I'm not making this up, it is future prophecy written in The Old Testament, but do your own homework.
The one thing that 2 Peter 3:8
doesn’t say, and which our Premillennial brethren often add into it is: ‘the day of the Lord is with the Lord as a thousand years, and a thousand years as the day of the Lord’. In fact, “the day of the Lord” is not even mentioned (or referred to) in the 1 day / 1,000 years equation. The above verses which the Premil often advances as evidence of a literal 1,000-year day of the Lord do not state what they say they do, namely that a day = a literal thousand years. The reading states, looking at the matter from a divine perspective, “one day is
with the Lord as a thousand years, and a thousand years as one day.” This is in total contrast to man’s limited standpoint, where one day is with him as simply one day. Also, the word “as” in this verse turns the whole phrase into a simile. A simile is defined in the American Heritage Dictionary as: “a figure of speech in which two essentially unlike things are compared, the comparison being made explicit typically by the use of the introductory ‘like’ or ‘as’.” This is therefore not meant to be viewed as a literal equation.
The ironic thing is that the reference to “one day” being with the Lord “as (or like) a thousand years, and a thousand years as (or like) one day” is not remotely speaking about a period subsequent to the second coming, but rather, a time preceding it. It is referring to the here-and-now and is specifically highlights the foolish limited temporal short-sighted reasoning of the wicked on earth before Christ’s Advent in glory in contrast to the supreme omniscience of a sovereign Lord.
The Premillennialist totally ignores the fact that the solemn message embodied within this reading is speaking about the “scoffers” in “the last days” who foolishly question the possibility of the impending return of Christ. It is not in any way concentrated upon a supposed group of millennial scoffers 1,000 years later or a period following the second coming of the Lord Jesus Christ. If this is supposed to be a collection of millennial inhabitants 1,000 years after the second coming, why would they be mocking “Where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of the creation”? Such a notion is completely absurd because Christ’s coming (or
parousia) would then be long past.
Those who spiritualize this day by stretching it out over the duration of a literal 1,000 years forget that the climactic detail embodied within the description of the said day destroys any credence that they have for forcing a Premillennial interpretation upon it. They completely demolish their own argument by advancing such an unlikely idea. They are quick to argue
day does not truly mean
a literal day in Scripture, and
hour doesn’t really mean
a literal hour, yet they always conveniently arrive at a literal future thousand-year millennium every time they examine the symbolic detail of Revelation 20.
The meaning and actual length of the
day mentioned here (however long it is), must relate to a specific time-period in which the detail described in the narrative continues throughout its duration. To argue otherwise is to totally deny the meaning of the passage. Moreover, whatever is portrayed within the aforementioned day is introduced suddenly to this kosmos – “like a thief in the night.” David Brown, in his classic book ‘Christ’s Second coming: Will it be Premillennial?’ rightly explains,
“terms and phrases, expressive of perpetuity, are to be stretched no further than the known duration of the thing spoken.”
