Sure I do.The first fruits of a harvest are gathered first.Aftet being gathered by the harvesters which are the angels,they are to be presented to the high priest (Christ)in Jerusalem.There is a celebration ,a feast and then rest.The regular harvest comes later.In this case after 1000 years.
Well I guess you do know what first fruits are. But you said they are the first resurrection, and they are not.
Additionally, the 144,000 are first fruits of the harvest that occurs at the 6th seal.
Seen here.
Matthew 24
29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
That harvest is also seen here.
Revelation 14
14 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
15 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
16 And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
17 And another angel came out of the temple which is in heaven, he also having a sharp sickle.
18 And another angel came out from the altar, which had power over fire; and cried with a loud cry to him that had the sharp sickle, saying, Thrust in thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe.
19 And the angel thrust in his sickle into the earth, and gathered the vine of the earth, and cast it into the great winepress of the wrath of God.
The great day of his wrath is come before the seventh is even opened.
It is right here listed under the events of he sixth seal.
Revelation 6
17 For the great day of his wrath is come; and who shall be able to stand?
They see Jesus sending His angels to gather the elect as Jesus remains in the clouds. After the gathering from heaven and earth those gathered go back to heaven for the marriage. Hence the great multitude in heaven in Revelation.
The kings of the earth and rich men etc try to hide because they realize that the great day of wrath is come. The seventh seal that contains the trumpets and vials of wrath.
What do you think those trumpets and vials of wrath are? Do you not realize they are the wrath of God?
