Isaiah 7:14, 9:6-7
Year after year, I find myself returning to the marvelous prophecy of Isaiah at during the Christmas season. Isaiah, who, writing in the 7th century B.C., provided the ancient Israelites very important prophetic insight about the Messiah Whom God the Father would send to His people.
Therefore the Lord Himself will give you a sign: Behold, the virgin shall conceive and bear a Son, and shall call His name Immanuel. Isaiah 7:14
6 For unto us a Child is born, Unto us a Son is given;
And the government will be upon His shoulder. And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace.
7 Of the increase of His government and peace There will be no end, Upon the throne of David and over His kingdom, To order it and establish it with judgment and justice From that time forward, even forever. The zeal of the Lord of hosts will perform this. Isaiah 9:6-7
Isaiah Tells Us What the Messiah Would Be Like
There is some debate about whether this designation constitutes one term (“Wonderful Counselor”; i.e., an adjective modifying a noun) or two (“Wonderful” and “Counselor”; i.e., two distinct qualities). There is no punctuation in Hebrew text, so this is an issue we cannot resolve from a study of the text itself. However, the difference is not something that radically changes the meaning. The term “wonderful” in Hebrew is used only to describe God. It is used 21 times in the Old Testament, every time referring to the work of God. For example, Isaiah 28:29 reads: “This also comes from the LORD of hosts, Who is wonderful in counsel and excellent in guidance.”
The Hebrew term "wonderful" refers only to “the ability to accomplish something that cannot be accomplished; to do or show marvelous works and miracles; to do the works only God can do.” Thus, the ability to perform miracles was the commonly accepted “sign” of God or God’s work and hence was referred to by the term used only for God and His works: “wonderful.”
