Biography

Isaiah son of Amoz ministered in Judah during the reigns of Uzziah, Jotham, Ahaz, Hezekiah, and likely into the shadow of Manasseh. His prophetic call came in the year King Uzziah died, when he saw the Lord high and lifted up, heard the seraphim cry “Holy, holy, holy,” confessed his uncleanness, received cleansing, and answered, “Here am I; send me.”

Isaiah’s ministry stands at a major historical turning point. Assyria was rising, the northern kingdom was collapsing, and Judah faced the temptation to seek safety through political alliances rather than trust in the LORD. Isaiah confronted unbelief in Ahaz, warned against reliance on Assyria and Egypt, and later strengthened Hezekiah during the Assyrian siege. In 2 Kings, Isaiah becomes the key prophetic voice during Sennacherib’s Defeat and Hezekiah’s Illness.

The book of Isaiah holds together judgment and hope. Isaiah exposes Judah’s corrupt worship, injustice, pride, and idolatry, but he also announces the remnant, the coming king from David’s line, the servant of the LORD, comfort for Zion, the gathering of nations, and the promise of new heavens and a new earth. His prophecies are among the most frequently echoed in the New Testament.

Isaiah is especially important for Christology. The virgin-born Immanuel, the child who is Mighty God and Prince of Peace, the Spirit-anointed servant, the suffering servant who bears sins, and the herald of good news all become major pathways for understanding Jesus Christ. Jesus reads Isaiah in Nazareth and declares its fulfillment in his own ministry.
