The reaping's of Revelation 14: 13 – 20,   (Jeff Unsworth) 
( Pre Wrath ) ( Futurist View)

The book of Revelation contains parenthetical chapters in between the chronological narrative of Revelation and these chapters are the writers way of giving a fuller understanding of what has gone on in previous chapters.
The parenthetical chapters are, Chapters 7, that deals with the Rapture of the church and the sealing of the 144,000 from the 12 tribes of Israel.
Chapters 12, 13 and 14, that deal with The rise of the Antichrist, The False Prophet, The Great Tribulation, and eventual destruction of Babylon the Great, and the harvesting of the believers and unbelievers. Then chapters 17 and 18 that deal with, in greater detail the fall of Babylon the Great.

Chapter 14 is a Parenthetical chapter dealing with what happens at the end of the Great Tribulation before the Wrath of God is poured out on the earth.
We see in chapter six, the sixth seal being opened. At this point the writer John pauses and takes us into his vision of heaven for a view of the 144,000 being sealed. They will be on the earth during the Great Tribulation and the Wrath of God.
We also see the raptured church in heaven at this time.

Revelation chapter 7: 9 – 15.
9.After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindred's, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;

10 And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb.

11 And all the angels stood round about the throne, and about the elders and the four beasts, and fell before the throne on their faces, and worshipped God,

12 Saying, Amen: Blessing, and glory, and wisdom, and thanksgiving, and honour, and power, and might, be unto our God for ever and ever. Amen.

13 And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they?

14 And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.

15 Therefore are they before the throne of God, and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them.
16 They shall hunger no more, neither thirst any more; neither shall the sun light on them, nor any heat.17 For the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes.

The Wrath of God begins to be poured out at the beginning of chapter eight when the 7th seal is opened and the first trumpet is sounded. It continues through to chapter 11.

Revelation Ch 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. 

We see the Son of Man ( Jesus) sitting on a cloud with a sickle. He thrusts His sickle into the earth and gathers the harvest.
(The harvest is a good reaping, the grain is ripe ) V15. 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. ( Notice the earth is ripe)
This is the Rapture of the church which occurs towards the end of chapter six. A pre wrath Rapture, caught up before the judgements.
We read of this in the parenthetical chapter 7 seen above. Notice, Jesus is sitting on a cloud and an angel calls with a loud voice.This fits in with Rapture scriptures such as: Revelation 1:7 (KJV) 
Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindred's of the earth shall wail because of him. Even so, Amen.

1 Thessalonians 4:16-17 (KJV) 16 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:17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.

Also at the Transfiguration, a cloud received Him and the Angels said that He would return in like manner as you see Him go. ( Coming with the clouds )
This is the reaping by Christ of all his saints, both dead and alive.
Then the writer John gives us a further description of the reaping of the unbelievers being gathered by the angels and these are thrown into the winepress of God’s wrath. This occurs at the end of the Wrath of God.

Rev 14: 18,19 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. ( Notice fully ripe—Vintage.)
( Notice also the angel came from the alter, which relates back to Rev Ch 6, where the souls of them that were slain for the testimony of Jesus, cried out, “ How long O Lord”.

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.

So in this parenthetical chapter, it appears that there are two reapings. One is done by Christ Himself (the Rapture) ( the ripe ) and the other is done by the Angels, (The gathering of the unbelievers) (the fully ripe)
..............................................

Other Futurists – who say the events in Revelation are largely unfulfilled, especially chapters 4-22 – are divided as to whether the harvest and the vintage refer to two separate actions, or one.
All are agreed that the vintage is the judgement of the wicked. But what about the harvest? Some expositors see it as the gathering of saints before judgement falls, while other see it as judgement of the wicked from a different perspective. The “One like the Son of Man” is Christ, who carries out judgement with His holy angels. The height and length of the flowing blood may be taken figuratively or literally, although it could mean the blood splatters as high as the horses’ bridles and covers the length of Israel.
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

The Reaping according to the A Millennial ( Idealist view ) also known as the “Symbolic View”, “Spiritualizing View” or “Poetic View”. ( Which is the allegorical method to interpret the Book of Revelation).
These Idealists, or spiritualists – who see Revelation setting forth timeless truths concerning the battle between good and evil – see the One seated on the cloud as Jesus. They understand the harvest and the vintage as final judgement but are also divided as to whether the harvest includes only the righteous or a combination of the righteous and the wicked, with the vintage providing a close-up of God’s wrath on the wicked. As for the 1,600 furlongs, many take this to be symbolic, derived from the square of four (the number of the earth) multiplied by the square of 10 (referring to completeness or divine perfection).

Conclusion: 

The Parenthetical chapter 7 gives the account of the believing church being present in Heaven after the Rapture.
The Parenthetical chapter 14 of Revelation seems to be a fuller explanation of the Rapture of the church, gathered by Christ Himself ( The gathering, )(Greek Episunagage) and which happens at the end of Revelation Chapter 6 and before the outpouring of Gods Wrath which begins in chapter 8. So in this parenthetical chapter 14, we do see two reaping's. One is done by Christ Himself (the Rapture) receiving the church to Himself and the other is done by the Angels, (The harvesting of the unbelievers) and being thrown into the winepress of Gods Wrath.The harvesting by the Angels in Revelation 14, is referring to the gathering of the unbelievers.
