Isaiah prophesied that the incarnate Jesus would be called “Everlasting Father,” among other titles listed in Isaiah 9:6. What does this title mean? Commentators have given a variety of answers to these words contained here:
For to us a child is born,
to us a son is given;
and the government shall be upon his shoulder,
and his name shall be called
Wonderful Counselor, Mighty God,
Everlasting Father, Prince of Peace.
Of the increase of his government and of peace
there will be no end,
on the throne of David and over his kingdom,
to establish it and to uphold it
with justice and with righteousness
from this time forth and forevermore.
The zeal of the Lord of hosts will do this. Isaiah 9:6-7 (ESV)
Jesus, the divine Son, in taking on human flesh, was qualified to fulfill God’s covenant requirements for man in ways that sinful men could not. He became the covenant fulfillment of those who had prefigured him in the Old Testament.
In the title Prince of Peace that comes after Everlasting Father it is easy to see that Jesus is the princely son of David who is qualified to sit on the throne of David forever as promised in 2 Samuel 7:13.
