Summary: The final judgment of God will separate between the saved and the unsaved like the threshing separates the chaff during harvest.
Before the Industrial Revolution of the 1800’s which introduced mechanized farming methods, different tools were used in the process undertaken during the harvest of cereals (wheat, maize, barley, rice etc.). The cereal crop was usually beaten out on a hard threshing-floor using threshing-tool such as a flail, then winnowing fans were used to blow the grain free of chaff after which the separated straw or husk was usually burned. There is a plantation in which the plants get nourishment, grow, and produce crops just like the one in your local farmer’s plantation. In this great plantation, the farm is the earth and the crops are human beings. What causes tears to gather is the fact that the chaff which is to be burned happen to be human beings. Surprisingly, it is a question of choice—a privilege that real plants do not have at all, anyone can choose ahead of time not to be the chaff. The field of Genetics, an outcome of the study of life on earth, teaches that at a TIME in the growth of a plant, genes which are inside the chromosomes in each plant cell begin to express themselves according to the type of plant part they will produce or become with each plant cell. This is the time and even NOW is the TIME to make the decision to be ’the grain.’ Beloved reader do not wait till the "time of anger"—of chaos, state of emergency, general fear and distress.
What should the rest of mankind do to avoid becoming the chaff? What do you need to do TODAY so as not to be burned? You need to decide so as not to become straw or husk. The opportunity to choose is not appreciated, especially in the matter of what lies ahead as soon as the soul of a person is knocked out of the body, that is, when the "silver cord" is broken, until the soul is actually separated from the body. Death. And it becomes late to help oneself. What follows is better imagined than experienced for any chaff.
"I looked, and there before me was a white cloud, and seated on the cloud was one "like a son of man" with a crown of gold on His head and a sharp sickle in His hand ... "Take your sickle and reap, because the time to reap has come, for the harvest of the earth is ripe."" (see the book of Revelation chapter 14) "... the field is the world, the good seeds are the sons of the kingdom, but the tares are sons of the wicked one ... The Son of Man will send out His angels, and they will gather out of His kingdom all things that offend, and those who practice lawlessness" (see Matthew chapter 13). The tares compare with the chaff of Matthew 3:12.
There is a variant of the chaff spoken of by the prophet Isaiah and also found in the book of Revelation. In this case, the chaff is grape: "I have trodden the wine-press alone, from the nations no-one was with me. I trampled them in my ANGER and trod them down in my WRATH; their blood spattered my garments, and I stained all my clothing." - See Isaiah 63:3. "The angel swung his sickle on the earth, gathered its grapes and threw them into the great wine-press of God’s wrath ... (Revelation 14:20).
