"Also I saw the souls of those who had been beheaded for the testimony of Jesus and for the word of God, and those who had not worshiped the beast or his image and had not received his mark on their foreheads or their hands. They came to life and reigned with Christ for a thousand years. 5The rest of the dead did not come to life until the thousand years were ended. This is the first resurrection. 6Blessed and holy is the one who shares in the first resurrection! Over such the second death has no power, but they will be priests of God and of Christ, and they will reign with him for a thousand years.
In the scripture above, John sees the GTS as beheaded, then he says "they came to life" and reigned with Christ for a thousand years. I would call that a resurrection.
I didn't miss the above, I just didn't comment on it. There are two harvests mentioned there. The second one is not a good harvest which is obvious and seems to be pointing to what happens when Jesus returns at Armageddon, as shown in Rev.19:15 "He will tread the winepress of the fury of the wrath of God the Almighty." And the first one doesn't say whether it is good or bad nor does it state who is being harvested or if it is in chronological order. There is just not enough information to say what or when that harvest is. Also, there are only two listed, for the 144,000 who is the male child is caught up to God's throne in the middle of the seven years as described in Rev.12:5
You're right that it doesn't say whether the first one is good or bad. It is sussed though, from COMPARING the two. Also, it seems apparent that the first reap is Jesus!
