CLAIM: Micah describes a time when the Messiah will rule in peace from Jerusalem over all the nations. This happens after God “threshes” the nations that oppose Him at the end of the age. Micah is speaking to Israel in his day, and predicting the people’s response to the horrific events that will lead to their ultimate deliverance from captivity and Babylon (v. 9-10). However, the “pain of their labor” related to what God wants to birth, is a description of deliverance that is far greater than the return from Babylon in 536 BC.
This is a last days prophecy, and the Lord’s house will be established as chief. This can only be through the church ruling and reigning, for Christ is the head of His church, and needs no other. When the missing broken off branches are grafted back into the olive bush, the “One New Man” (see here for further discussion) will experience “life from the dead” (Romans 11:15). It mentions no longer learning war, so this cannot be Millennial under any interpretation, because the Gog Magog conflict comes after it.
