Taught by God

Micah 4:2  
2 Many nations shall come and say, “Come, and let us go up to the mountain of the Lord, to the house of the God of Jacob; He will teach us His ways, and we shall walk in His paths.”  For out of Zion the law shall go forth, and the word of the Lord from Jerusalem.

Hebrews 1:1-4  1 God, who at various times and in various ways spoke in time past to the fathers by the prophets, 2 has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the worlds; 3 who being the brightness of His glory and the express image of His person, and upholding all things by the word of His power, when He had by Himself purged our sins, sat down at the right hand of the Majesty on high, 4 having become so much better than the angels, as He has by inheritance obtained a more excellent name than they.

The promise through Abraham for all nations to be God's shows His Law was to bring us to realize our desperately sin-filled nature which keeps us from walking in His ways.  So His Son Jesus, who shows us God did for us what we could not, speaking the final words of salvation which the prophets only pointed to.  We can only walk in His ways by His sacrifice for us, His presence (Spirit) within us, with a new heart from a new birth as a new creation by God.  We are taught by God (John 6:45, 1 Thessalonians 4:9) to walk in His ways by His Spirit and word.
