Isaiah 32 is a chapter about things being set right in the world. It's set in a section that's comprised of warnings about the dangers of failing to follow God or of putting trust in a different protector. The message about God is that he requires a consistency and transparency in his creation and in his people. It explains why we see suffering in the world, and teaches us of principles to live by.
1. The World Made Right
In Isaiah 32, we see a vision of how things will be in the world when God's plan is enacted. It starts at leadership, with the promise that there will be a king and rule that is righteous and just.
Isaiah 32:1: Behold, a king shall reign in righteousness, and princes shall rule in justice. WEB
Although we're in an era now where the political rulers have limited respect, and often treated with contempt to the favour of popularist views, the history of the nation of Israel shows that time and time again, the attitudes of the people are strongly influenced by the leaders of the society. So here we see the king reigning in righteousness as a light that shines giving hope for the common people.
There is a consistency that for things to be right in the world, the regard for God needs to run right through society - from top to bottom. In looking over the history of Israel, we can see evidence of this, with the times of faithful leadership leading to periods were the people followed God.
During the time of the Judges, there was a continual oscillation of the people between following God, and ignoring him for the alternatives. In Judges 3, God raised up Ehud as a Judge do deliver Israel. When they turned to God, they were released from oppression. However, after Ehud died and the leadership was lost, the people as a whole again forsook God.
Judges 4:1: The children of Israel again did that which was evil in the sight of Yahweh, when Ehud was dead. WEB
For the society of Israel to work, they needed a faithfulness that spread right through the society. A righteous king is a valuable asset.
Consistency to be Restored
When Isaiah 32 describes the changed world under the righteous king, it does so with slightly unexpected illustrations.
The most natural description of the glory of the future age comes in passages like Isaiah 65, where there is presented a picture of peace, joy and freedom from harm.
Isaiah 65:18: But be you glad and rejoice forever in that which I create; for, behold, I create Jerusalem a rejoicing, and her people a joy. 19. I will rejoice in Jerusalem, and joy in my people; and there shall be heard in her no more the voice of weeping and the voice of crying. WEB
However, in chapter 32, the emphasis is different. Instead, here we see a more fundamental change taking place. It's a change to make things right - to return things to the way they should be. The blessing is in that the reality is to match the appearance.
Isaiah 32:2: A man shall be as a hiding-place from the wind, and a covert from the tempest, as streams of water in a dry place, as the shade of a great rock in a weary land. 3. The eyes of those who see shall not be dim, and the ears of those who hear shall listen. 4. The heart of the rash shall understand knowledge, and the tongue of the stammerers shall be ready to speak plainly. 5. The fool shall be no more called noble, nor the scoundrel be highly respected. WEB
It speaks of a time when things will work as they are designed: an eye that is made for seeing will be able to see, and the ear that is designed for hearing will be able to hear. Something that looks like an ear will truly be an ear, and someone who is in a position of nobility will truly be noble.
It confirms God's distaste for things having an appearance different to their reality:
Isaiah 5:20: Woe to those who call evil good, and good evil; Who put darkness for light, And light for darkness; Who put bitter for sweet, And sweet for bitter! WEB
Under the rule of the righteous king, instead of this being a confusing and deceitful world, it is one where things are clear, and right and wrong can be seen.
