The Great Winepress - Revelation 14:17-20

Revelation 14:17-20 ESV 

Then another angel came out of the temple in heaven, and he too had a sharp sickle.

And another angel came out from the altar, the angel who has authority over the fire, and he called with a loud voice to the one who had the sharp sickle, “Put in your sickle and gather the clusters from the vine of the earth, for its grapes are ripe.”

So the angel swung his sickle across the earth and gathered the grape harvest of the earth and threw it into the great winepress of the wrath of God.

And the winepress was trodden outside the city, and blood flowed from the winepress, as high as a horse's bridle, for 1,600 stadia.

Another angel appears with a sickle, but without a crown. This one does have authority over the fire of the Lord. The sickle swings not to reap, but gather. Those branches that do not produce the fruit of God are heaped together for the burning. 

The fruit gathered is from the false vine of the earth. Jesus is the true vine and apart from Him we can do nothing towards life. Blood will flow and a third of the waters will turn red, made bitter by wormwood, also known as Satan.
