"sister Dora Van Assen. Many years ago she wrote, “What is the chaff to the wheat? ‘Whose fan is in His hand, and He will thoroughly purge His floor, and gather His wheat into the garner; but He will burn up the chaff with unquenchable fire’ (Mat. 3:12). ‘Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them; but gather the wheat into my barn’ (Mat. 13:30)."
"For years I read eternal torment into the foregoing scriptures. I had the wheat as all the saved people taken to heaven, the chaff and tares as all the unsaved people put in hell to be burned with a literal unquenchable fire; until God spoke to my heart saying: ‘You cannot have wheat without chaff, for it takes the chaff to hold the wheat until it is fully matured, and only then can it be threshed, removing the chaff without damaging the seed of life. So this is done at the end of the harvest when the seed is fully grown.’ Thus God gradually began to open my eyes to see that the chaff and the wheat were both in my own self; that my natural Adam nature or human identity was the chaff encasing the wheat, the very life-seed of Christ; that I was being born of an incorruptible seed, and that seed is Christ in me, the hope of glory. These scriptural concepts began to take on new meaning in a most wonderful way!"
“I then began to see that it is first the natural and then the spiritual (I Cor. 15:44-46); that without the natural we could not contain the spiritual. We are an earthen vessel holding a ‘treasure’ which is the very excellency of God (II Cor. 4:7). Be glad, therefore, for this natural creation because out of it God brings forth a NEW CREATION! If the chaff is removed before the wheat is mature, it will do damage to the wheat. It is needed to hold the wheat as it passes from the milk stage into the fully hardened and mature stage, where it can be removed from the chaff without harming the wheat in any way. Then the wheat is placed in the barn and the chaff is burned. Today in this enlightened age, even the chaff has many useful purposes, but in ancient times it was simply disposed of by fire. There is absolutely no waste in the economy of God! The prophet inquired, ‘What is the chaff to the wheat?’ (Jer. 23:28). Praise God, it is the super-structure, scaffolding, or encasement which covers and holds the wheat intact as it grows into the very likeness of the One who planted it within. All seed brings forth after its own kind. So, Christ shall see His seed and be satisfied when it comes into His own image and likeness!"
The entire in the link:
I don't know who sister Dora Van Assen is, but this is quite good. The rapture in Revelation 14:15 and elsewhere is depicted as a harvest, and the harvest cannot come until the wheat is ripe, or mature. What matures the wheat? The heat of the sun, which signifies tribulation. May we all grow and mature in Christ in these coming days!
