What does Micah 4:2 mean?

Nations will say, 'Come on, let’s go up to the Lord’s mountain, to the house of the God of Jacob. He’ll teach us how to live, and we’ll walk in his ways.' Because God’s instructions will go out from Zion, and his word will come from Jerusalem. Micah 4:2 - Modern Text Bible

(Here, people from every nation are eager to learn from God, seeing his wisdom as the guide for real life. Jerusalem becomes the source of truth for everyone.)
