More threshing is occurring, beginning two days ago.  Threshing in grain harvesting was done to separate the ‘inedible’ grain (chaff) from the edible (good seed).  The good grain would be left to the floor and gathered into the storehouse, but the chaff would be thrown to the wind.

Threshing symbolizes judgment.  Hosea addressed this issue with the Israelites when they continuously went back to their idols before the living God.  God’s judgment on them was to scatter them to the winds.  Those that are the chaff at this hour WILL and HAVE been carried away by the wind.  In Ephesians 4:14 it explains those that would ‘remain on the ground’ were the ‘edible’ grain.  However, those that were blown away are said to be like children, in their knowledge of things of God, like infants, basically knowing nothing or being limited.  In addition, those infants are easily swayed by every wind of doctrine, never really coming to the knowledge of the truth because they listen to others’ leading in all things.  They were also considered infants because they were worldly/fleshly in nature (1Cor. 3:1), not led in the Spirit of Truth or by the leading of the Holy Spirit, but by their own deceitful hearts.

In Hebrew, doctrine can mean:  an instruction (either an active or sinister sense), learning, instruction, or announcement, rumor

Paul goes onto say that these teachings/instructions/announcements/rumors, were performed by the cunningness and craftiness of people in their deceitful scheming.

This great threshing has performed a judgment at this time between those that are left to be invited into the storehouse as the good grain and those that will be swept away in the unquenchable fire, as the chaff experiences after it’s been tossed into the wind.  Christ is doing this and will continue to do this.  He has the winnowing fork in His hand.

Matt.3:12  12 His winnowing fork is in his hand, and he will clear his threshing floor, gathering his wheat into the barn and burning up the chaff with unquenchable fire.”

Psalm 1:4  Not so the wicked! They are like chaff that the wind blows away.

Isa. 17:13  Although the peoples roar like the roar of surging waters, when he rebukes them they flee far away, driven before the wind like chaff on the hills, like tumbleweed before a gale.
