Does Jesus come at the Second Coming with a sickle to perform the harvest?

Absolutely not.

But the Son of man does come to do that work of harvest exactly where we find on the chart where "it is written" "The Slaying of Those Who Have Not the Seal. So we can turn off the brightness of this coming, make it invisible, and see it as the fulfillment of Matt. 13:30.

     Inescapably, therefore, the Lord's coming to His temple (Mal. 3:1-3), His coming with all His angels (Matt. 25), and His coming enthroned above the living creatures (Ezek. 1),—all three representing THE SAME EVENT as has been shown,—take place at the beginning of the judgment of the living: the time in which the judicial activities of the heavenly sanctuary extend to the earthly sanctuary—the church.—3Tr:47.3

Now, look down below from where the slaying takes place, where the statue of Daniel 2 is illustrated, what is it representing?

In order for the stone to smite the image at its feet, it must be in existence before the woman gives the kings of the earth to drink from that "golden cup." Ths same stone that was cut out at the TIME of the purification of the church, the "firstfruits" harvest, is the one later used to smite the present world at its feet WHEN the woman sits on the beast.

Therefore, the stone MUST first come into existence before the woman sits on the seven heads. And the stone smites the image as soon as the woman takes her seat on the SCB. Even an inaccurate "error" turns out to be a blessing in disguise for the stone is set up in the Assyrian period, not Babylon.

     "When the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come." Christ is waiting with longing desire for the manifestation of Himself in His church. When the character of Christ shall be perfectly reproduced in His people, then He will come to claim them as His own.—COL 69.1
