In Isaiah 6:1–8, we witness Isaiah’s divine calling and his commissioning into the prophetic office. A key moment appears in verse 5, where Isaiah’s immediate reaction to God’s holy presence is recorded.
Isaiah 6:5 I said, “It’s all over! I am doomed, for I am a sinful man. I have filthy lips, and I live among a people with filthy lips. Yet I have seen the King, the Lord of Heaven’s Armies.”
The presence of the LORD exposed the filth and sin of Isaiah. The nature of the presence he encountered can be seen in verse 2-3.
The presence Isaiah encountered was utterly holy. In that radiant holiness, the depth of his own sin and impurity was exposed. He saw himself as a broken, unclean man—one whose very lips were unworthy—when he stood before the holiness of the Lord. His sincere confession and honest acknowledgment of his sin opened the way for God’s cleansing work. This divine purging is vividly portrayed in verses 6–7
Right after his purging and cleansing by the LORD, he stepped into the prophetic office. This is also noted in verse 8.
What did Isaiah believe about God?
When Isaiah encountered the holy presence of the Lord, he immediately recognized himself as a sinner—specifically a man of unclean lips. What caused such a confession? His response was shaped by the very nature of God. Habakkuk 1:132:22 highlights God’s deep displeasure toward sin, revealing that sin stands in direct opposition to His holy nature.
Habakkuk 1:13; “Your eyes are too pure to look on evil; you cannot tolerate wrongdoing.”
In His holiness, God hates sin, and Scripture declares that He hates all who do wrong. Therefore, when Isaiah entered the holy presence of the Lord, the purity of God’s character exposed the sinful nature of Isaiah. Even if Isaiah had understood nothing else in that moment, he knew this much with absolute certainty: the Holy God despises sin and is utterly holy. This conviction aligns with the declaration in Psalms 5:4-5, which affirms that God is not pleased those who do wicked.
Psalm 5:4–5: “For you are not a God who is pleased with wickedness; with you, evil people are not welcome. The arrogant cannot stand in your presence. You hate all who do wrong.”
Did Isaiah ever doubt God when the Lord spoke to him? The answer is no. Throughout his ministry, every message God entrusted to Isaiah proved true, and every prophecy unfolded just as God declared. This consistent fulfillment of God’s word demonstrates that Isaiah never wavered in trusting what God revealed to him. His confidence rested in the character of the God who cannot lie and whose word never fails.
In Isaiah 9 it reveals a prophecy about a future Messiah. This Messiah is described in verse 6 as a child who will be born… implying that whoever this messiah is, will walk the earth as a man with flesh and blood. However, in that same verse, the identity of the child is revealed.
Prophecies
Isaiah 9:6 For a child is born to us, a son is given to us. The government will rest on his shoulders. And he will be called: Wonderful Counselor, [d] Mighty God, Everlasting Father, Prince of Peace.
The identity of the Child is revealed as none other than God (Yahweh) Himself. Isaiah’s prophecy points to a future moment when God would enter the world in human form to redeem humanity from sin. Throughout the book, Isaiah’s Messianic prophecies consistently reinforce this conviction. These include:
Isaiah 7:14 – “Behold, the virgin shall conceive and bear a son and shall call his name Immanuel.”
This verse is seen as a prophecy of the virgin birth of Jesus, with “Immanuel” meaning “God with us”.
Isaiah 9:6–7 – “For to us a child is born, to us a son is given… and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.
”This passage emphasizes the divine titles and eternal reign of the coming Messiah.
Isaiah 11:1–2 – “A shoot will come up from the stump of Jesse… The Spirit of the Lord will rest on him.”
This points to the Messiah’s Davidic lineage and the anointing of the Holy Spirit.
Isaiah 40:3–5 – “A voice of one calling: ‘In the wilderness prepare the way for the Lord…’” Interpreted as referring to John the Baptist preparing the way for Jesus.
Isaiah 42:1–4 – Describes the “Servant of the Lord” who will bring justice to the nations, a prophecy linked to Jesus’ ministry of peace and justice.
Isaiah 50:6 – “I gave my back to those who strike, and my cheeks to those who pull out the beard…” Seen as a foreshadowing of Jesus’ suffering during His Passion.
Isaiah 53 – Perhaps the most detailed Messianic prophecy, describing the “Suffering Servant”: “He was pierced for our transgressions… by his wounds we are healed.” This chapter is often cited as a vivid portrayal of Jesus’ sacrificial death and atonement for sin.
Isaiah 61:1–2 – “The Spirit of the Sovereign Lord is on me… to proclaim good news to the poor.” Jesus read this passage in the synagogue (Luke 4:18–21), declaring its fulfillment in Himself.
