Charles Spurgeon Commentary Revelation 14:18

"And another angel came out from the altar, he that hath power over fire; and he called with a great voice to him that had the sharp sickle, saying, Send forth thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe." — Revelation 14:18 (ASV)

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.

This is the ingathering of the ungodly: they are not the Lord's harvest; they are the vintage of his wrath. This vintage is not reaped by him who wears the golden crown, the Lord Jesus Christ himself; but by one of his angels, who is commanded to thrust in his sharp sickle, and reap, for the hour of divine judgment has at last come.
