Micah is not a well studied book. After the death of Solomon, his son Jeroboam wanted to follow God. Israel splits between the North, Israel, and the south, Judah. Around 700 B.C. northern Israel begins to assimilate with Juda, bring their foreign gods they imported from Syria. Micah wrote at the same time as Isiah and Jermaine; he preaches against the conflict of Israeli life, the worshiping of foreign gods. Through out Jewish history there was only a remnant of God's people; same today regarding Christians.
Micah is divided into 3 sections. 1) The first section, 1-2:13, Micah telling everyone to listen up; 2) Section two, 3-5, 5:15 is about the Masonic hope, talking to the leaders of the nation. 3) Section 3,6-7, 6:1-7:7, an oratory urging, encouraging or strongly advising a course of action: Return to God; stop serving the false gods. If we follow God's covenant, we will be blessed; if not then what happens in Micah. Chapter 1:1 will apply to us.
Who judges inequities? Only God. The law can't judge because the sin is internal. Transgression is the visibly breaking of the law. The people, during Micah's time, were committing apostasy. God provided the blood, the "kifar", to wash away our inequities and transgression. Micah 2:13, "I will raise up the Breaker who will go before us, and He will lead the remnant out."
