When the prophet Isaiah wrote (9.6-7) of a coming King who would establish the throne of his forefather David he said some mighty amazing things. He wrote this,

For to us a child is born,
to us a son is given,
and the government will be on his shoulders.
And he will be called
Wonderful Counselor, Mighty God,
Everlasting Father, Prince of Peace.

Of the greatness of his government and peace
there will be no end.
He will reign on David’s throne
and over his kingdom,
establishing and upholding it
with justice and righteousness
from that time on and forever.
The zeal of the LORD Almighty
will accomplish this. (NIV)

I know that other famous Israelites had names like אֵ֣ל גִּבּ֔וֹר where El is part of the name (e.g. Elijah = YHWH is God), so this doesn’t mean someone is deity. Nevertheless, there is a lot of “divinity” attributed to this character. He is a “wonderful” (פֶּ֠לֶא) counselor, which is a near divine wisdom. He is said to be the “Father of eternity” or “Everlasting Father”, which is a lot to say of any human. Yet he is a son, a child, and a prince of shalom.

The reign of this King is וְעַד־עוֹלָ֔ם, which can be a very, very long time, but it would could be a sense of “forever” as well. If we take any on of these aspects separately we can say there are reasons to avoid assuming a “divine” son, but if we read the whole thought block it is hard to avoid. Even if it is “exalted” language, it is saying something very impressive about this person.

Did the prophet know of whom he spoke? Maybe, but only through a glass darkly. Can we “prove” that this passage refers to Jesus Christ? No, but if we are Christians it is impossible to imagine who else fulfills these words. Personally, I cannot see anyone but Jesus here. Jesus is the one who is the divine counselor through the Spirit. He is the one who embodies the mighty God. He is the one who shows us the Father or “fathers” us into eternity. He is the only son/child who qualifies to be the Prince of shalom. And it is in Christ alone that we see the Davidic throne established forever.
