Please note the word “kings” or “all kings” in some of the quoted verses such as the one below in this brief write up:

“Nations will come to Your Light, And kings to the Brightness of Your Rising.” (Isaiah 60:3, NASB)

“All the kings of the earth will give thanks to You, O LORD,

When they have heard the words of Your mouth.

And they will sing of the ways of the LORD,

For great is the glory of the LORD” (Psalm 138:4 – 5, NASB)

“Yea, all kings shall fall down before Him: all nations shall serve Him.” (Psalm 72:11, KJV)

When ‘their kings’ return to Lord Jesus Christ, the ‘rest’ will follow.

Can we see it?

“Kings will be your guardians, And their princesses your nurses. They will bow down to you with their faces to the earth And lick the dust of your feet; And you will know that I am the LORD; Those who hopefully wait for Me will not be put to shame.” (Isaiah 49:23, NASB)

“So the nations will fear the name of the LORD And all the kings of the earth Your glory.

When the peoples are gathered together, And the kingdoms, to serve the LORD.” (Psalm 102:15, 22, NASB)

Conclusion

“Thus He will sprinkle many nations, Kings will shut their mouths on account of Him; For what had not been told them they will see, And what they had not heard they will understand.” (Isaiah 52:15, NASB)

“Who will have all men to be saved, and to come unto the knowledge of the truth.” (1 Timothy 2:4, KJV)

“This is a faithful saying and worthy of all acceptation.

For therefore we both labour and suffer reproach, because we trust in the Living God, Who is the Saviour of all men, specially of those that believe.

These things command and teach” (1 Timothy 4:9 – 11, KJV)

This is the Meaning of “Living God” (please note this phrase in verse above) in that He “Saves” —> “All men”, eventually.

So, as Christians, are we ready to “teach” & “command” —> “these things” (regarding God Saving “all men”) —> but “believers” are more special (how? Example: ‘no’ afterlife Judgment for believers, John 5:24)) —-> as the last verse above instructs?

P/S:

“Then I will teach transgressors Your ways, And sinners will be converted to You.” (Psalm 51:13, NASB)

“And in that Day there shall be a Root of Jesse, which shall stand for an ensign of the people; to it shall the Gentiles seek: and His Rest shall be Glorious.” (Isaiah 11:10, KJV)

“And in His Name shall the Gentiles trust.” (Matthew 12:21, KJV)

“so that the Gentiles may Glorify God for His Mercy. As it is written: “Therefore I will praise You among the Gentiles; I will sing hymns to Your name.” (Romans 15:9, BSB)
