Not if one believes the Book of Revelation Chapter 20 is the infallable Word of God.. In that chapter it clearly reveals two resurrections with 1000 years in between them.. The Entire word of God must be accepted.. Not just verses quoted in isolation.. I encourage you to sit down and simply read the Chapter..
Your claim is in error, (The Souls) seen in Revelation 6:9 below, are the exact same (Souls) seen in Revelation 20:4 below in parallel teachings, they are given white robes, and are reigning with the Lord in the spiritual, prior to the second coming, the (Little Season) that they are waiting for is for the tribulation to end at the (Second Coming) of Jesus Christ.
There is no literal 1,000 earthly years seen, this represents the (Little Season) in the spiritual, Revelation 6:9-11 & Revelation 20:4-6 is 100% in the Lords spiritual realm of no earthly time, one day is a thousand years, not literal 2 Peter 3:8 (Be Not Ignorant)
When the term (First Resurrection) is used, it means nothing more than two resurrections are seen below in John 5:28-29, the saved righteous souls,that are reigning in white robes, and dead in the Lord are (Blessed) to be in this first resurrection, because the (Second Resurrection) seen below is the second death, in the Lake of fire for the wicked.
Revelation 6:9-11KJV
9 And when he had opened the fifth seal, I saw under the altar
the souls of them that were slain for the word of God, and for the testimony which they held:
10 And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?
11 And white robes were given unto every one of them; and it was said unto them, that
they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they were, should be fulfilled.
Revelation 20:4-6KJV
4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw
the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
5 But the rest of the dead lived not again until the thousand years were finished. This is
the first resurrection.
6 Blessed and holy is he that hath part in
the first resurrection: on such
the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
John 5:28-29KJV
28 Marvel not at this: for the hour is coming, in the which
all that are in the graves shall hear his voice,
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.
