Micah 4:1 NASB

Again, the Life Application Study Bibles states: the last days refers to the days when God will reign over his perfect kingdom. Although we cannot know for certain the date this will begin, we know that God has promised that it will arrive.

Mican predicts the end of the kings, which was a drastic statement to the people of Judah. After a period of time, God would return His people to their land, which happened just as Micah said.

God wants us to change our behavior because of what we know about the future. A glimpse of God's plan for us should motivate us to serve Him.
