How many resurrections that are still to take place are implied in the New Testament?
Could what is described in Revelation 6:9-10 be considered as resurrection?:
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: 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?
In the end of Revelation we see at least two separate resurrections on each side of the millennium kingdom:
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 worshiped 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 (Revelation 20:4)
And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is [the book] of life: and the dead were judged out of those things which were written in the books, according to their works (Revelation 20:12)
But in the First Thessalonians Paul speaks about one more resurrection:
For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first (1st Thessalonians 4:16)
On the other hand, I also heard that in Philippians 3:11 Paul also speaks about some kind of extra-resurrection:
If by any means I might attain unto the resurrection of the dead
And also, both the Savior and Martha mention resurrection that will happen on the last day:
And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day (John 6:40)
Martha saith unto him, I know that he shall rise again in the resurrection at the last day (John 11:24)
Some of all these resurrections may actually be referring to the same resurrection.
There may also be other resurrections mentioned in the New Testament that I haven't brought up here.
So, how many different instances of the future resurrections are reserved in the New Testament?
