Theme - Micah's ministry differed from that of Isaiah in that he was of the common people and deeply sympathized with them in the social wrongs imposed upon them; whereas, Isaiah was of the nobility and directed his prophesies to the capital city and to the political issues of the times. His labours began about 740 B.C. and continued to about 700 B.C.; hence, he lived and prophesied during the evil times of the closing years of the Northern Kingdom and witnessed the complete overthrow of that nation by Assyria.

The great truths of Micah's prophecy cover the destruction of the Northern Kingdom; the desolation of Jerusalem and the Temple; the captivity of Judah in Babylon; the restoration of Judah; the coming of the Messiah, and the time and place of his birth.

Outline - Micah may be divided into four main sections: I. The Impending Calamity (1) II. The Sins Which Brought on the Calamity (2-3) III. The Promised Restoration and Blessings (4-5) IV. God's Controversy with Israel (6-7)

According to Ussher, Micah's ministry covered a period of forty years.
