This text seems pivotal to the discussion at hand, and like Revelation, it is from the Johannine texts.
John 5:24-30
24 “Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life. 25 Most assuredly, I say to you, the hour is coming, and now is, when the dead will hear the voice of the Son of God; and those who hear will live. 26 For as the Father has life in Himself, so He has granted the Son to have life in Himself, 27 and has given Him authority to execute judgment also, because He is the Son of Man. 28 Do not marvel at this; for the hour is coming in which all who are in the graves will hear His voice 29 and come forth—those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of condemnation. 30 I can of Myself do nothing. As I hear, I judge; and My judgment is righteous, because I do not seek My own will but the will of the Father who sent Me. (NKJV)
This does seem to indicate a reality at the time of crossing from death to life through belief, and a later reality of those in the grave being resurrected physically--both those going to life, and those to condemnation.
And a number of verses speak of believers, through baptism, participating in the death, burial and resurrection of Christ.
Does this match up with the context of Revelation?
Revelation 20:4-6
4 And I saw thrones, and they sat on them, and judgment was committed to them. Then I saw the souls of those who had been beheaded for their witness to Jesus and for the word of God, who had not worshiped the beast or his image, and had not received his mark on their foreheads or on their hands. And they lived and reigned with Christ for a thousand years. 5 But the rest of the dead did not live again until the thousand years were finished. This is the first resurrection. 6 Blessed and holy is he who has part in the first resurrection. Over 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. (NKJV)
It depends on how you interpret the element of those who were beheaded, who did not receive the mark. This seems to be a specific, limited group.
And it would also depend on when you see this mark being fulfilled.
@prodromos @The Liturgist do EO take this to be about Nero? Or some other fulfillment?
Obviously, for Adventists the mark is at the end of time. But they brush over that part of the text, because that would limit it to a specific group who were martyred and did not receive the mark. And they apply it to all the righteous.
