>>17624258Isaiah 2:1-4 prophecies of a future law be given for judging between the nations.
The word that Isaiah the son of Amoz saw concerning Judah and Jerusalem.
2 It shall come to pass in the latter days
that the mountain of the house of the Lord
shall be established as the highest of the mountains,
and shall be lifted up above the hills;
and all the nations shall flow to it,
3 and many peoples shall come, and say:
“Come, let us go up to the mountain of the Lord,
to the house of the God of Jacob,
that he may teach us his ways
and that we may walk in his paths.”
For out of Zion shall go forth the law,[a]
and the word of the Lord from Jerusalem.
4 He shall judge between the nations,
and shall decide disputes for many peoples;
and they shall beat their swords into plowshares,
and their spears into pruning hooks;
nation shall not lift up sword against nation,
neither shall they learn war anymore.
But in the OT we see God judging nations and he could only do that according to a law because he is just and righteous. We may not have a narrative of how God spoke to those people in all cases, but we know the character of God.
Romans 2:14-16
For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law (the law of Moses)
They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them on that day when, according to my gospel, God judges the secrets of men by Christ Jesus.”
