Meaning of Isaiah 42:21

This verse from Isaiah 42:21 reveals a profound theological concept: the divine motivation behind the Law's exaltation. It is not for the Law's intrinsic merit alone, but "for the sake of his righteousness" that God chose to magnify and glorify His Law. This means God's perfect character, His inherent justice and holiness, is the ultimate reason why His commands are presented as great and glorious. The Law, therefore, is not merely a set of arbitrary rules but a reflection of God's own righteous nature, intended to reveal Him and guide humanity in a way that aligns with His perfect being. This act of making the Law "great and glorious" demonstrates God's commitment to His own standards and His desire for His people to participate in that righteousness.

Context and Background

Isaiah 42 is part of the "Servant Songs" within the book of Isaiah, which prophesy about a coming Servant who will bring justice and salvation to the nations. This particular passage is spoken by God concerning His chosen Servant, who is tasked with establishing justice on earth. The verse directly follows a lament by the Servant, who feels his efforts have been in vain. God's response here, in verse 21, is to affirm the purpose and magnificence of the Law, even in the face of apparent human failure to uphold it. The Law, in this context, is not just the Mosaic Law but represents the totality of God's revealed will and standards.

Key Themes and Messages

• Divine Motivation: The primary theme is that God's actions, including the exaltation of His Law, are rooted in His own righteousness. His glory and justice are the driving forces.
• Magnification of the Law: The Law is not presented as a burden but as something "great and glorious." This highlights its inherent value, its divine origin, and its capacity to reveal God and His will.
• Purpose of the Law: The Law serves to make known God's character and to provide a standard for human conduct that reflects His righteousness. It is a tool for revealing God's justice.
• Sovereignty of God: The verse underscores God's sovereign decision to make His Law so prominent, demonstrating His control and purpose in its establishment.

Spiritual Significance and Application

Spiritually, this verse calls believers to view God's Law not as a restrictive set of rules, but as a magnificent revelation of God's own perfect character. It encourages a deeper appreciation for the Law's purpose: to guide us into a life that honors God and reflects His righteousness. Understanding this motivation can transform our perspective on obedience, shifting it from a reluctant duty to a joyful participation in God's glorious design. It also emphasizes that true spiritual growth involves aligning our lives with God's righteous standards, not for our own merit, but for the glory of God.

Relation to the Broader Biblical Narrative

This verse is a crucial bridge in the biblical narrative. It anticipates the coming of Jesus Christ, who is the ultimate embodiment of God's righteousness and the one who perfectly fulfilled the Law. Jesus declared, "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them" (Matthew 5:17). The Law, made great and glorious by God's decree, finds its ultimate expression and fulfillment in Christ, who then imparts His righteousness to believers through faith. This verse also foreshadows the New Covenant, where God's Law is written on the hearts of His people, enabling them to live in accordance with His righteous will.

Analogies

Think of a master architect designing a magnificent cathedral. The blueprints, while detailed and intricate, are not merely a set of instructions; they are the embodiment of the architect's vision, skill, and aesthetic principles. God, as the divine architect, has made His Law "great and glorious" because it is a reflection of His own perfect design for humanity and His own righteous character. Just as the cathedral's grandeur inspires awe and reveals the architect's genius, so too God's Law, in its greatness and glory, reveals the perfection of its divine author. Another analogy is a skilled musician composing a symphony. The score, filled with complex melodies and harmonies, is not just a list of notes but a profound expression of the composer's artistry and intent. God's Law is similarly a beautiful and intricate expression of His righteous heart.

Relation to Other Verses

• Psalm 119:97: "Oh, how I love your law! I meditate on it all day long." This Psalm reflects the deep affection and value placed on God's Law, aligning with Isaiah's depiction of its greatness.
• Romans 7:12: "So the law is holy, and the commandment is holy and righteous and good." Paul echoes the sentiment that the Law itself is inherently good, a testament to its divine origin.
• Matthew 5:17: As mentioned earlier, Jesus' affirmation of fulfilling the Law directly relates to God making it great and glorious, as Christ is the ultimate fulfillment.
• 1 John 3:4: "Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness." This verse highlights the concept of sin as a transgression of God's Law, underscoring the Law's role as a standard of righteousness.
