THE MEANING OF ISAIAH 28:23-29 NEB.
"Listen and hear what I say, attend and hear My words. Will the ploughman continually plough for the sowing, breaking his ground and harrowing it? Does he not, once he has levelled it, broadcast the dill and scatter the cummin? Does he not plant the wheat in rows with barley and spelt along the edge? Does not his God instruct him and train him aright?
Dill is not threshed with a sledge, and the cartwheel is not rolled over cummin; dill is beaten with a rod, and cummin with a flail. Corn is crushed, but not to the uttermost, not with a final crushing; his cartwheels rumble over it and break it up, but they do not grind it fine. This message, too, comes from the Lord of Hosts, whose purposes are wonderful and His power great." (Isaiah 28:23-29 NEB).
The spiritual language of God expressed through the prophet Isaiah describes the wonderful way and loving consideration of God for those He trains. In this analogy, Almighty God is the "ploughman" adopting diverse methods to sow various "seeds" in the spirits of mankind, and spiritually refining them according to their various natures and degrees of faith that they may serve Him. But to avoid crushing their spirits, He carries out this process discreetly, with the right measure of corrective discipline, and never beyond what a human spirit can bear.* Never to the uttermost crushing. This is in order that those whose spirits He has trained are made ready for everlasting spirit life in the heavenly realm with Almighty God Jehovah and other members of heavenly Mount Zion. (Hebrews 12:22-24 NEB).
*"So far you have faced no trial beyond what man can bear. God keeps faith, and He will not allow you to be tested above your powers, but when the test comes He will at the same time provide a way out, by enabling you to sustain it." (1 Cor 10:13 NEB).
