The main aspects of God that Micah emphasized were His sovereignty, self-consistency, and His leadership of all events and His people toward His ultimate plans and purposes for them.
Like the other eighth-century prophets, Micah attacked the idolatry that accompanied the acceptance of Canaanite worship. However, his distinctive burden was the social injustices that marked the ruling class (2:1, 8-9; 3:11; 6:11; cf. Amos). He was a champion of civil rights.
Micah wrote about the coming Messiah. He predicted His birthplace, lineage, and origin (5:2), His future reign (4:1-7; 5:4), and referred to Him as Israel's king (2:13) and ruler (5:2).
"Micah's doctrine of the remnant is unique among the Prophets and is perhaps his most significant contribution to the prophetic theology of hope. The remnant is a force in the world, not simply a residue of people, as the word remnant' (she'erit) may seem to imply. It is a force that will ultimately conquer the world (4:11-13). This triumph, while presented in apparently militaristic terminology (4:13; 5:5-6), is actually accomplished by other than physical force [cf. Matt. 5:3-12]. By removing everything that robs his people of complete trust in him (5:10-15), the Ruler from Bethlehem will effect the deliverance of his people. The source of power for God's people in the world is their absolute trust in him and his resources."3
As many of the prophetical books, Micah is primarily poetry. One of the prominent features of Hebrew poetry is parallelism of thought, and this marks Micah. Micah used his native language as a craftsman. He utilized puns, wordplays, and probing questions. This book, like the other Prophets, is a collection of messages that Micah delivered.
There is one citation from Micah in the Old Testament and two in the New. The elders of Jerusalem in Jeremiah's day referred to Micah to support not persecuting Jeremiah for predicting judgment on Jerusalem (Jer. 26:17-19). Matthew quoted Micah 5:2 as predicting the birthplace of Messiah (Matt. 2:5-6), and he recorded Jesus' quotation of Micah 7:6 regarding conflict within families (Matt. 10:35-36).
"In OT study Micah has tended to be overshadowed by Amos and Hosea and especially by his great contemporary Isaiah, whose prophetic material has been preserved in much greater quantity. Stylistically, to be sure, he sometimes has more of the qualities of an orator than of a poet. But his message is proclaimed with no uncertain sound, as with passionate forthrightness he attacks the social evils of his day. His stubborn refusal to float on the tide of his social environment, and his courageous stand for his convictions of God's truth, must commend Micah to believers in every age."4
