“And the light of Israel shall be for a fire, and his Holy One for a flame: and it shall burn and devour his thorns and his briers in one day; and shall consume the glory of his forest, and of his fruitful field, both soul and body: and they shall be as when a standardbearer fainteth. And the rest of the trees of his forest shall be few, that a child may write them.” Isaiah 10:17-19 (KJB)
In this reading I want us to remember that the Light of the world is Jesus Christ the Son of God and God the Son,
These words of Isaiah were spoken by God to him of the judgment God was bringing on the nation He was using to judge His own people because they had turned from the LORD God. This judgment is against Assyria whose ruler thought he was in charge, he was no one’s servant, that he was so powerful he had done all the conquering on his own. God was set to show him other wise.
The judgment of God is always for the cleansing of His people.
I am going to close with the words of the Matthew Henry Commentary…
“How this destruction is represented. It shall be, First, As a consumption of the body by a disease: The Lord shall send leanness among his fatnesses, or his fat ones. His numerous army, that was like a body covered with fatness, shall be diminished, and waste away, and become like a skeleton. Secondly, As a consumption of buildings, or trees and bushes, by fire: Under his glory, that very thing which he glories in, he will kindle a burning, as the burning of a fire, which shall lay his army in ruins as suddenly as a raging fire lays a stately house in ashes. Some make it an allusion to the fire kindled under the sacrifices; for proud sinners fall as sacrifices to divine justice. Observe, 1. How this fire shall be kindled, Isa_10:17. The same God that is a rejoicing light to those that serve him faithfully will be a consuming fire to those that trifle with him or rebel against him. The light of Israel shall be for a fire to the Assyrians, as the same pillar of cloud was a light to the Israelites and a terror to the Egyptians in the Red Sea. What can oppose, what can extinguish, such a fire? 2. What desolation it shall make: it shall burn and devour its thorns and briers, his officers and soldiers, which are of little worth, and vexations to God’s Israel, as thorns and briers, whose end is to be burned, and which are easily and quickly consumed by a devouring fire. “Who would set the briers and thorns against me in battle? They would be so far from stopping the fire that they would inflame it.
I would go through them and burn them together (Isa_27:4); they shall be devoured in one day, all cut off in an instant.” When they cried not only Peace and safety, but Victory and triumph, then sudden destruction came; it came surprisingly, and was completed in a little time. “Even the glory of his forest (Isa_10:18), the choice troops of his army, the veterans, the troops of the household, the bravest regiments he had, that he was most proud of and depended most upon, that he valued as men do their timber-trees (the glory of their forest) or their fruit-trees (the glory of the Carmel), shall be put as briers and thorns before the fire; they shall be consumed both soul and body, entirely consumed, not only a limb burned, but life taken away.” Note, God is able to destroy both soul and body, and therefore we should fear him more than man, who can but kill the body. Great armies before him are but as great woods, which he can fell or fire when he pleases.
[3.] What would be the effect of this great slaughter. The prophet tells us, First, That the army would hereby be reduced to a very small number: The rest of the trees of his forest shall be few; very few shall escape the sword of the destroying angel, so few that th ere needs no artist, no muster-master or secretary of war, to take an account of them, for even a child may soon reckon the numbers of them, and write the names of them. Secondly, That those few who remained should be quite dispirited: They shall be as when a standard-bearer fainteth. When he either falls or flees, and his colours are taken by the enemy, this discourages the whole army, and puts them all into confusion. Upon the whole matter we must say, Who is able to stand before this great and holy Lord God?” MATTHEW HENRY COMMENTARY
Turn to Jesus Christ the Light of the world. Without Him there is no light. He died for you, He was buried, and He rose again; and He forever lives and hears us when we pray trusting Him.
