Biography

Isaiah son of Amoz prophesied in Judah from approximately 740 to 680 BC, serving under four kings: Uzziah, Jotham, Ahaz, and Hezekiah. His call to ministry came in 'the year that king Uzziah died' (Isaiah 6:1) — about 740 BC. In the temple Isaiah saw a vision of God enthroned, surrounded by seraphim crying 'Holy, holy, holy, is the LORD of hosts.' Isaiah responded with confession of unworthiness; a seraph touched his lips with a coal from the altar to purify him; then God called him to prophetic ministry. Isaiah's lifetime spanned the Assyrian crisis. The northern kingdom of Israel was destroyed by Assyria in 722 BC. Judah was threatened repeatedly. Sennacherib of Assyria invaded in 701 BC and besieged Jerusalem; through Isaiah's prophecy and Hezekiah's prayer, the angel of the LORD struck down 185,000 Assyrian soldiers in one night (Isaiah 37:36). The book of Isaiah has 66 chapters — sometimes called 'the Bible in miniature' for its parallel structure. The first 39 chapters emphasize judgment; the last 27 emphasize comfort and the gospel. Major prophecies include: a virgin shall conceive (Isaiah 7:14), 'unto us a child is born' (9:6), the Spirit-anointed Messiah (11:1-5), the new heavens and new earth (65:17), and the Suffering Servant (Isaiah 53) — the most extensive prophecy of Christ's atoning death in the Old Testament. Tradition holds that Isaiah was martyred under King Manasseh by being sawn in two — referenced in Hebrews 11:37.

Theological Significance

Isaiah is the most-quoted Old Testament prophet in the New Testament. His Messianic prophecies — virgin birth, the Spirit-anointed king, the Suffering Servant, the new creation — are foundational to Christian understanding of Christ. Isaiah 53 alone is so directly applied to Jesus that some early Christians called it 'the fifth Gospel.' His vision of God in the temple (Isaiah 6) is the classic Old Testament account of encountering divine holiness.
