Jesus Christ

The Focus of Isaiah's Message

Donald W. Parry, "Jesus Christ: The Focus of Isaiah's Message," in Search Diligently the Words of Isaiah (Provo, UT: Religious Studies Center, Brigham Young University; Salt Lake City: Deseret Book), 518.

Several New Testament passages make it clear that the Old Testament, which includes Isaiah’s writings, reveals Jesus Christ (see John 1:45; 5:39; Luke 24:27, 44; Acts 8:26–35; 10:43; 18:24–25, 28). The writings of Isaiah are no exception—they, too, focus on him. In fact, he is the major focus of Isaiah’s writings. Isaiah speaks of the first coming of Jesus; he writes in detail and with great clarity on the subject of the Atonement of Jesus; and he prophesies of the Second Coming of Jesus and his millennial reign. Nephi’s words support the understanding that Isaiah’s text refers to Jesus Christ: “That I might more fully persuade them to believe in the Lord their Redeemer I did read unto them that which was written by the prophet Isaiah” (1 Nephi 19:23).[1] In this chapter, we will explore some ways in which Isaiah’s text focuses on Jesus Christ.

Jehovah is Jesus Christ

It is crucial to recognize that the word Jehovah (translated “LORD”[2] in the King James Version) is “the covenant or proper name of the God of Israel” and that Jehovah himself is none other than “the premortal Jesus Christ” (Bible Dictionary, “Jehovah”). Several Church authorities have affirmed the truth that Jesus Christ is Jehovah. President Gordon B. Hinckley stated in 2008, “Jesus was in very deed the great Jehovah of the Old Testament.”[3] In 2017, President Russell M. Nelson implored, “Commence tonight to consecrate a portion of your time each week to studying everything Jesus said and did as recorded in the Old Testament, for he is the Jehovah of the Old Testament.”[4] In “The Living Christ: The Testimony of the Apostles,” written in 2000, the First Presidency and Quorum of the Twelve Apostles asserted that Jesus Christ is “the Great Jehovah of the Old Testament, the Messiah of the New.”[5] There are many similar statements by other Church authorities. Those who accept the teaching that Jesus Christ’s premortal name was Jehovah have a completely different view regarding the prominence of Jesus Christ in Isaiah’s text. This perspective is owing, in part, to the fact that the name Jehovah (LORD) is found about 450 times in Isaiah.

In addition to the 450 instances of the word LORD in Isaiah, there are literally hundreds of pronouns that refer to Jehovah. These include possessive pronouns (such as your, his, my), independent pronouns (you, he, I), and direct or indirect objects (him, me). As we become more aware of the hundreds of pronouns that refer to the LORD, we will better appreciate Jesus Christ’s presence in the book of Isaiah.

Isaiah’s Prophecies of the Messiah, Jesus Christ

Although Isaiah lived about 700 years before Jesus’s birth, he was both a remarkable and prominent witness for the Messiah, Jesus Christ. Isaiah’s messianic prophecies pertain to Jesus’s birth, names, disposition, earthly ministry, compassion, rejection by the people, trial, sufferings, Atonement, blotting out our sins, Crucifixion, death, burial, Resurrection, exaltation, and blessings. While a few of Isaiah’s prophecies are presented with the use of symbols (“H shall grow up . . . as a tender plant” [Isaiah 53:2]), others are submitted with clarity and precise language (“H was wounded” [Isaiah 53:5]).

Through the ages, Isaiah’s prophecies have benefited and inspired millions. Songwriters and poets have used his words when composing their works, and teachers and preachers have stirred people with their sermons and lessons when they have taught Isaiah’s messianic prophecies. Tables 2.1 and 2.2 set forth a representative selection of Isaiah’s prophecies concerning Jesus Christ.

Isaiah 53—Isaiah’s Acclaimed Prophecy of the Messiah and the Atonement

Isaiah 53 is one of the greatest messianic prophecies about Jesus Christ’s atoning sacrifice. Matthew, Philip, Paul, Peter, and Abinadi all applied portions of Isaiah 53 to Jesus Christ (see Matthew 8:17; Acts 8:26–35; Romans 4:25; 1 Peter 2:24–25; Mosiah 14–16). Isaiah 53 sets forth four recurring themes, intermingled throughout the chapter, that provide detailed descriptions of the Lord’s sufferings and Atonement (see table 2.3).

Jehovah is the Savior and the Redeemer

Several verses of Isaiah reveal that the Lord is our Savior and our Redeemer. In fact, in many instances, the Lord himself designates that he is the Savior and the Redeemer. Examples are set forth in tables 2.4 and 2.5.

Table 2.4. Designations in Isaiah that the Lord is Savior

“For I am the Lord thy God, the Holy One of Israel, thy Saviour”&Բ;43:3
“I, even I, am the Lord; and beside me there is no saviour43:11
“Verily thou art a God that hidest thyself, O God of Israel, the Saviour45:15
“There is no God else beside me; a just God and a Saviour45:21
“All flesh shall know that I the Lord am thy Saviour and thy Redeemer”49:26
“I the Lord am thy Saviour and thy Redeemer, the mighty One of Jacob”60:16

Note: Emphasis added.

Names, Titles, and Metaphors for the Lord

There are scores of names, titles, and metaphors that describe God in the writings of Isaiah. Each name or title serves to describe God’s perfections, divine attributes, and mission to humankind. For example, Beloved, Righteous Servant, and Wonderful describe his divine qualities; Rock, Stone, Song, and Water are metaphors that describe one or more aspects of his nature or character; Judge, King, and Lawgiver set forth three of his roles in the plan of salvation; Most High, Prince of Peace, and King portray his exalted position and majesty; God, Lord God, Creator, Almighty, and Lord of Hosts explain that he is our Supreme Being, our God; and Redeemer, Salvation, Lamb, and Savior describe aspects of his atoning sacrifice.

Some of these names and titles appear once only in Isaiah, while others are attested multiple times. The names Holy One of Israel, God, Lord, Lord God, Lord of Hosts, and Redeemer, for instance, each appear a dozen or more times in the book of Isaiah.

Table 2.6 lists scores of names, titles, and metaphors that describe God, together with a single reference from Isaiah. There are doubtless other names and titles that could be added to this list.

God-Compound Names: Personal Names including God or Lord

The Israelites sometimes gave their children Hebrew names composed of two separate elements—a name of God plus a grammatical component, such as a noun or verb. Scholars call these theophoric (Greek, “bearing the name of God”) names or God-compound names. Attentive readers of the Old Testament may have noticed personal names that include the element -el (Hebrew, signifies God). Sometimes -el appears at the beginning of names, such as Eldad, Eliab, Eliakim, and Elimelech; on other occasions, -el appears at the end of the names, such as Gabriel, Immanuel, Daniel, Joel, and Michael. The fact that there are scores of -el names in the Old Testament underscores their importance and relays the possibility that many ancient Israelite parents desired that their children’s names bear the name of God. Each God-compound name has a special meaning that teaches us something about God himself. For example, the name Uzziel (God is my strength) shows that God is our strength; and Daniel (God is my judge) presents God’s status as judge. God-compound names that are attested in Isaiah are listed in table 2.7, together with their possible meanings.[7]

Table 2.7. God-Compound Names in Isaiah

Name Name in HebrewPossible Meaning
ArielאריאלLion of God
EliakimאליקיםGod will raise up
Immanuelאל עמנוGod is with us
Israel ישראלlet God prevail

In addition to -el names, the Old Testament includes scores of compound names that mean “Lord.” These are presented with the suffix -iah, the prefix Jo-, or other forms (both -iah and Jo- signify “Lord” in Hebrew). Lord-compound names in Isaiah are listed in table 2.8. Note that the meanings of some names are subject to dispute.

Note that the meanings of some names are subject to dispute.

Equivalent Designations of the Lord in Isaiah and the New Testament

There are several designations (descriptions, names, or titles) of the Lord in Isaiah that correspond with Jesus Christ in the New Testament. The following list sets forth three examples:

  1. The Lord is designated King: “Mine eyes have seen the King, the Lord of hosts” (Isaiah 6:5). Jesus Christ is also denominated King in the New Testament, with these words: “Lord of lords, and King of kings” (Revelation 17:14).
  2. The Lord in Isaiah is designated Rock: “Because thou hast forgotten the God of thy salvation, and has not been mindful of the rock of thy strength” (Isaiah 17:10; emphasis added). Jesus Christ is also a Rock: “For they drank of that spiritual Rock that followed them: and that Rock was Christ” (1 Corinthians 10:4).
  3. The Lord reveals, “Unto me every knee shall bow, every tongue shall swear” (Isaiah 45:23). Correspondingly, the Apostle Paul wrote of Jesus Christ, “At the name of Jesus every knee should bow” (Philippians 2:10).

Table 2.9 presents several other examples of designations of the Lord in Isaiah that correspond with Jesus Christ in the New Testament, including Almighty, Creator, Everlasting God, Judge, Redeemer, Savior, and Servant.

Proper understanding of these designations can give great insight into the Lord Jesus Christ and his divine and formidable work with individuals, peoples, and nations in both Isaiah and the New Testament. These designations also provide straightforward and direct evidence that Jesus Christ is indeed Jehovah of the Old Testament. Beyond the examples in the table, many others could also be set forth.

In this chapter, we looked at several important elements in the book of Isaiah that support the Christian view that Jesus Christ is the focus of Isaiah’s message. We referred to the words of living prophets, who have stated clearly that Jehovah is none other than Jesus Christ. Additionally, we looked at Isaiah’s prophecies of the Messiah Jesus Christ, with special focus on Isaiah 53, a famous prophecy of the Messiah and the Atonement. We also examined scriptural passages in Isaiah that state clearly that Jehovah is the Savior and the Redeemer; names, titles, and metaphors for the Lord; God-compound names (or personal names that include God or Lord); and equivalent designations of the Lord in Isaiah and the New Testament. When brought together, all these elements demonstrate that Isaiah’s writings are focused and centered on Jesus Christ.

Notes

[1] Citing this verse (1 Nephi 19:23), Elder Jeffrey R. Holland wrote, “We can help the whole world be ‘more fully persuaded’ of Christ’s divinity because of our Latter-day Saint view of him as seen through the eyes of Isaiah.” “‘More Fully Persuaded,’” 2.

[2] There are two words with distinct meanings that are translated very similarly in the KJV: “Lord” (lowercase except the L), which is translated from Adonai, meaning “lord” or “master”; and “LORD” (all uppercase), which is translated from the name Jehovah. In this book we will preserve this distinction between Lord and LORD.
