Where does it say they were gathered by angels?
I never said they were gathered by angels. The Lord Himself comes for them as He is on Mount Sion with the 144,000 and then redeems them from the earth. See the 1st 3 verses of Rev 14.
The 144k are sealed between the 6th and 7th Seals being opened. You are changing around the chronological order to fit your personal theology.
I am not changing the Chronological order. I am understanding what I am reading?
Most people think that the 144,000 are sealed to go through the wrath of God. They do not go through the wrath of God. We are not appointed to wrath. Only the nation of Israel, those that flee to a place of protection and unbelievers go through the wrath of God.
The first point is that 144,000 are first fruits that are redeemed from the earth. What are they first fruits of? They are first fruits of the second harvest. Where does the second harvest place? It takes place at the 6th seal. Here is that harvest? It is marked by the signs of the sun, moon and stars that occur at the 6th seal.
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.
What is the result of the harvest that occurs at the 6th seal?
Revelation 7
9 After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;
The harvest is the great multitude which includes the Church, which is gathered from heaven, and the those of the 12 tribes that are gathered from the earth. All return to heaven after the marriage supper.
Since we see the harvest in heaven after the 6th seal we know that the first fruits of the harvest, the 144,000 have to be in heaven before the 6th seal. Can we prove that? ABSOLUTELY.
When we are reading Revelation 13 and 14 we are back in the seals. We know that because the wrath of is over because the kingdoms of this world are become the kingdoms of our Lord at the 7th trumpet
Here we see the 144,000 redeemed from the earth.
Revelation 14
3 And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth.
Here we see the Great Tribulation?
Revelation 14
13 And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
The Great Tribulation is the 5th seal.
Here is the coming of Jesus at the 6th seal for the harvest.
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.
Here is the wrath of God which is the 7th seal.
Revelation 14
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.
In conclusion, when we understand what we are reading it all fits together perfectly.
