Which would you agree with,
Discipline is not punishment
or
Punishment is not discipline?

Is the Investigative Judgment Biblical?
That is the theme of the thread.

I think both Kland and Mountain Man agree that some people will enjoy everlasting life, while others will reap everlasting death.

So who determines who will come up in the first resurrection and who will come up in the second resurrection?

I believe that is determined in Pre-Advent judgment.
In the pre-advent judgement, the Bridegroom (Christ) intercedes for His bride --
Every person He can, by His blood, redeem, cleanse and present before the Father and the heavenly angels, will be raised to partake of that marriage supper of the Lamb.


Rev. 3:5 He that overcometh, the same shall be clothed in white raiment; and I (Jesus) will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
3:12 I will write upon him the name of my God, and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God: and [I will write upon him] my new name.
Rev. 19:7 Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife hath made herself ready.
19:8 And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints.
19:9 And he saith unto me, Write, Blessed [are] they which are called unto the marriage supper of the Lamb.
20:6 Blessed and holy [is] he that hath part in the first resurrection: on such the second death hath no power,
The second resurrection occurs 1000 years later, but their names are not found in the book of life.
20:15 And whosoever was not found written in the book of life was cast into the lake of fire. (14) This is the second death.

God does things in a orderly way, and the process where He does the Judgment is no different.

that is incorrect.

revelation 20:4 specifically says, "I saw the souls of those who had been beheaded because of their testimony about Jesus and because of the word of God. They had not worshiped the beast or its image and had not received its mark on their foreheads or their hands. They came to life and reigned with Christ a thousand years."

so then here are people who everyone knows:

1. had been beheaded, AND
2. had testified about Jesus, AND
3. had not worshiped the beast or its image, and had not received its mark

are sda planning on beheading each other in order to make the cut?

There is sufficient evidence in the study of Yom Kippur to lay this to rest.
But perhaps it is not evidence of truth that is wanted, but evidence to believe what folks want to believe.

******* STAFF EDIT *******

.....that specifically and unequivocally and plainly say who will be part of the first resurrection: viz-a-viz, those who had been beheaded rev. 20:4

sad!

Rev. 20:4 Gives the assurance to those who who faced martyrdom that they will be raised In the first resurrection. It's a promise that has enabled many persecuted ones to hold fast to their faith even at the cost of their earthly life.
However, the idea that they are the only ones raised is purely an assumption, other texts seem to indicate that all the "dead in Christ" will be raised in that first resurrection.
1 Thessalonians 4:16 gives a larger picture as the apostle Paul teaches, "For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first."
Who are these "dead in Christ"? I don't think they are ONLY the martyred ones?
The last part of verse 17 then notes, "so we will always be with the Lord." All believers will from that point forward be with Christ forever.

The Bible speaks of two resurrection:
The first is the resurrection of life at the beginning of the 1000 years.
The second is the resurrection of damnation at the end of the 1000 years.

John 5:28 Marvel not at this: for the hour is coming, in which all that are in the graves shall hear his voice,
5:29 And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.

Rev. 20:6 Blessed and holy is he that has part in the first resurrection: on such the second death has no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years. "
20:5 the rest of the dead lived not again until the thousand years were finished



So yes, the decision as to who "is in Christ" and will be raised in the first resurrection is revealed in the heavenly court, surrounded by millions of angels, prior to the second coming. Christ presents their names before the Father (See Rev. 3:5)
