The calling of the prophet Isaiah, recorded in Isaiah 6, stands as one of the most striking encounters with God’s holiness in all of Scripture. In a vision of overwhelming majesty, Isaiah saw the Lord seated on His throne, surrounded by angelic beings proclaiming His absolute holiness. The experience left him undone, painfully aware of his own sinfulness. Yet, in an act of divine grace, he was cleansed and commissioned for his prophetic mission. However, his calling was not one of national revival or success. Rather, he was sent to a people whose hearts were hardened, a people who would not listen. His message would confirm their blindness and rebellion, leading to inevitable judgment. This passage holds deep theological weight, not only for its portrayal of God’s glory but also for its prophetic implications regarding Israel’s future.

From a Dispensational perspective, Isaiah’s vision is critical because it highlights both Israel’s historical exile and its ultimate redemption. The hardening of Israel’s heart, foretold in Isaiah 6:9-10, would culminate in the nation’s captivity under Assyria and Babylon. Yet, even as judgment loomed, God’s covenantal promises to Abraham and David remained unbroken. Though Israel would suffer for its rebellion, a faithful remnant would be preserved, and one day, the nation would be restored. This passage ultimately points toward the Messianic Kingdom, when Israel’s blindness will be lifted, and they will recognize Jesus as their true King. Paul later referenced this prophecy in Romans 11:25-27 to explain Israel’s temporary rejection of Christ and their future national salvation.
A Nation in Decline: The Death of King Uzziah
The vision took place “in the year that King Uzziah died,” marking a pivotal transition in Judah’s history (Isaiah 6:1). Uzziah had ruled for fifty-two years, bringing military victories, economic prosperity, and national stability. Yet his reign ended in disgrace when, in pride, he unlawfully entered the temple to burn incense. As a result, God struck him with leprosy, and he lived out his final years in isolation (2 Chronicles 26:16-21). With his death, Judah faced an uncertain future. Assyria was rising in power, threatening the region, while spiritually, the nation was in decline, marked by corruption and idolatry (Isaiah 1:4-6). It was at this moment, with the earthly throne in turmoil, that Isaiah saw the eternal throne of God.
Isaiah’s Vision and Cleansing
Isaiah’s vision was nothing short of overwhelming. He saw the Lord exalted, His robe filling the temple, a display of divine majesty and authority. Around Him were seraphim, angelic beings who cried out:
“Holy, holy, holy is the Lord Almighty; the whole earth is full of His glory.”
(Isaiah 6:3)
The repetition of “holy” emphasized the absolute purity of God, a holiness beyond human comprehension. As their voices resounded, the temple shook, and smoke filled the air. The scene was one of unapproachable glory, and Isaiah, standing before it, was overcome with a sense of doom.
His immediate reaction was not awe or elation but despair. “Woe to me!” he cried. “I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips.” (Isaiah 6:5). The sight of God’s holiness made Isaiah acutely aware of his own sinfulness. In that moment, he understood that no one could stand before a holy God without purification.
The Symbolism of the Burning Coal
A seraph took a burning coal from the altar and touched Isaiah’s lips, declaring:
“See, this has touched your lips; your guilt is taken away and your sin atoned for.”
(Isaiah 6:7)
The burning coal symbolized purification, foreshadowing the ultimate atonement that would come through Christ. Just as Isaiah was cleansed to serve as God’s prophet, so too will Israel one day be spiritually cleansed before entering the Messianic Kingdom, as foretold in Zechariah 13:9.
The Hardening of Israel’s Heart
Once purified, Isaiah heard the voice of the Lord asking, “Whom shall I send? And who will go for us?” Without hesitation, Isaiah responded, “Here am I. Send me!” (Isaiah 6:8). His willingness to go, however, was met with a sobering commission. Rather than bringing revival, his mission would harden hearts. God instructed him:
“Go and tell this people: ‘Be ever hearing, but never understanding; be ever seeing, but never perceiving.’”
(Isaiah 6:9)
Isaiah’s words would not lead to repentance but would confirm the people’s spiritual blindness. The more he preached, the more resistant they would become. This prophecy was later referenced by Jesus in Matthew 13:14-15 and by Paul in Acts 28:26-27, explaining Israel’s rejection of the Gospel. However, as Paul clarified in Romans 11, this blindness is temporary. Though Israel rejected their Messiah, God’s promises to them remain, and in the future, they will turn back to Him.
A Future of Judgment and Restoration
Faced with such a grim message, Isaiah asked, “For how long, Lord?” The answer was devastating:
“Until the cities lie ruined and without inhabitant, until the houses are left deserted and the fields ruined and ravaged.”
(Isaiah 6:11)
This prophecy foreshadowed the destruction of the northern kingdom by Assyria in 722 B.C. and the fall of Judah to Babylon in 586 B.C. Yet, even in the midst of judgment, hope remained. God revealed that a remnant would survive:
“But as the terebinth and oak leave stumps when they are cut down, so the holy seed will be the stump in the land.”
(Isaiah 6:13)
Though Israel would be cut down, a remnant would endure, ensuring that God’s covenantal promises would not fail. This points forward to the ultimate restoration of Israel in the end times, when they will be fully regathered and reconciled to their Messiah.
Dispensational Significance: A Dual Prophecy of Judgment and Redemption
Isaiah’s calling is not just a historical event but a prophetic blueprint of Israel’s spiritual journey. It illustrates the cycle of sin, judgment, and restoration that defines their national history. Though the nation faced exile and suffering, God’s faithfulness never wavered. One day, their spiritual blindness will be lifted, and they will recognize Christ as their King. Paul’s words in Romans 11:26 reaffirm this promise:
“And so all Israel will be saved, as it is written: ‘The deliverer will come from Zion; He will turn godlessness away from Jacob.’”
Just as Isaiah’s lips were touched with fire, so too will Israel be purified in the refining fire of tribulation, emerging as a nation fully devoted to the Lord.
A Call to Holiness and Hope
Isaiah’s vision reveals God’s holiness, human sinfulness, and the certainty of judgment. Yet, it also points to future restoration—the day when Israel’s blindness will be removed, and Christ will reign as King. His calling was not one of easy success, but it was one of profound significance. Through judgment, exile, and restoration, the hand of God remained upon His people. The same God who called Isaiah continues His work today, unfolding His redemptive plan, which will culminate in the glorious reign of Christ over all the earth.
“The whole earth is full of His glory.”
(Isaiah 6:3)
