I agree it has some relevance. However it is just as predictable. There is no great sign here, just some mile markers posting the final (easily forseen) invasion of Israel and Juda.
Therefore it CAN be interpreted in a contemporary sense, but it just doesn’t have a satisfying “greatness” to the sign.
Notice the child’s name “God with us.” Prophecies can and often do shimmer between many different fulfillments.
I think Matthew 1:23 is still the best interpretation, and at last we have our Great Sign given by God.
I don’t think it was easily foreseen yet when the time Isaiah made this declaration. At least, if you’re Ahaz.
See, from 2 Kings we know that Ahaz turned for help to Assyria against the Syro-Ephraimite coalition. (Essentially, what happened is, the kings of Israel and Aram, Pekah and Rezin, were trying to coerce Judah to join them in their alliance against the Assyrian Empire. When Judah refused, the alliance mounted an invasion, bent on either forcing Ahaz to join them or overthrowing and replacing him with a puppet government.)
For Assyria to invade Judah as well would have been the last thing to cross Ahaz’s mind. Essentially, what Isaiah is telling Ahaz is that he shouldn’t be lulled into a false sense of security: Assyria will deal with Israel and Syria, but it will also ultimately turn against Judah. And all this because Ahaz decided to place his trust in the king of Assyria instead of the God of Judah.
Then Rezin king of Syria and Pekah the son of Remaliah, king of Israel, came up to wage war on Jerusalem, and they besieged Ahaz but could not conquer him. At that time Rezin the king of Syria recovered Elath for Syria and drove the men of Judah from Elath, and the Edomites came to Elath, where they dwell to this day. So Ahaz sent messengers to Tiglath-pileser king of Assyria, saying, “I am your servant and your son. Come up and rescue me from the hand of the king of Syria and from the hand of the king of Israel, who are attacking me.” Ahaz also took the silver and gold that was found in the house of the Lord and in the treasures of the king’s house and sent a present to the king of Assyria. And the king of Assyria listened to him. The king of Assyria marched up against Damascus and took it, carrying its people captive to Kir, and he killed Rezin.
This is apparently why Ahaz refused to ask for a sign even though God Himself commanded him to do so: he thought he had the situation under control. He had just entered into an alliance with the bigger fish (Assyria).
So what God told him in reply essentially is, “Yeah, Assyria
is going to thrash Aram and Israel, but it will come after you too.” That might be the explanation of the name Immanuel (‘God is with us’) in the original context: it’s a kind of
warning to Ahaz. God is right here - why then does Ahaz and the people act as if He’s not? (Needlessly fearing the Syro-Ephraimite alliance and then entering a false sense of security once the alliance with Assyria was made.)
The Lord spoke to me again: “Because this people has refused the waters of Shiloah that flow gently, and rejoice over Rezin and the son of Remaliah, therefore, behold, the Lord is bringing up against them the waters of the River, mighty and many, the king of Assyria and all his glory. And it will rise over all its channels and go over all its banks, and it will sweep on into Judah, it will overflow and pass on, reaching even to the neck, and its outspread wings will fill the breadth of your land, O Immanuel.”
Be broken, you peoples, and be shattered;
give ear, all you far countries;
strap on your armor and be shattered;
strap on your armor and be shattered.
Take counsel together, but it will come to nothing;
speak a word, but it will not stand,
for God is with us. (
kî ‘immānû ’ēl)
For the LORD spoke thus to me with his strong hand upon me, and warned me not to walk in the way of this people, saying: “
Do not call conspiracy all that this people calls conspiracy, and do not fear what they fear, nor be in dread. But the LORD of hosts, him you shall honor as holy. Let him be your fear, and let him be your dread. And he will become a sanctuary and a stone of offense and a rock of stumbling to both houses of Israel, a trap and a snare to the inhabitants of Jerusalem. And many shall stumble on it. They shall fall and be broken; they shall be snared and taken.”
“Bind up the testimony; seal the teaching among my disciples. I will wait for the LORD, who is hiding his face from the house of Jacob, and I will hope in him.
Behold, I and the children whom the Lord has given me are signs and portents in Israel from the LORD of hosts, who dwells on Mount Zion. And when they say to you, “Inquire of the mediums and the necromancers who chirp and mutter,” should not a people inquire of their God? Should they inquire of the dead on behalf of the living? To the teaching and to the testimony! If they will not speak according to this word, it is because they have no dawn. They will pass through the land, greatly distressed and hungry. And when they are hungry, they will be enraged and will speak contemptuously against their king and their God, and turn their faces upward. And they will look to the earth, but behold, distress and darkness, the gloom of anguish. And they will be thrust into thick darkness.”
