King of the Nations.

God the Father will give His Son, as His inheritance, the nations.

`Ask of me and I will give you the nations for your inheritance.` (Ps. 2: 8)

In the Tribulation - the Great Multitude of the Nations.

During the tribulation when God`s judgments are poured He still has His hand of mercy outstretched to those who repent. A great multitude, that no one can count of the nations, died of hunger, heat and thirst but `washed their robes in the blood of the Lamb.` (Rev. 7: 9 - 16)

And those who do not bow to the anti-Christ.

Then there are those who did not bow to the image of the anti-Christ, nor took his mark, number or name, but looked for Israel`s Messiah to come and set up His righteous kingdom through Israel. (Rev. 15: 2) They sang the song of Moses and the song of the Lamb.

`Great and marvellous are your works, Lord God Almighty! Just and true are your ways, O King of the Holy Ones, (of the nations). Who shall not fear you, O Lord, and glorify your name?` (Rev. 15: 3)

The Song of Moses. He ascribed greatness to God, His work perfect, and all His ways, just. As one of the two witnesses of Christ, Israel`s coming Messiah, he would have witnessed of Christ, His greatness and justice. (Rev. 11: 3- 6)

`Ascribe greatness to our God. He is the Rock, His work is perfect; for all His ways are justice.`  (Deut. 32: 3 & 4)

The Song of the `Lamb` refers to Christ`s sacrifice as Israel`s Passover Lamb. It is His title as the victor standing on Mount Zion in glory, the One who overcame Satan and his world government. It is Christ`s `battle scarred dress,` in which He fought and won to receive the greatest honour. `Behold, a Lamb standing on Mount Zion...` (Rev. 14: 1)

These `holy ones,` also reveal that all the nations will come and worship the Lord. 

`For you alone are holy. For all nations shall come and worship before you, for your judgments have been manifested.` (Rev. 15: 4)

After the tribulation all nations under Christ the King of the Nations.

The Lord will judge the nations as to who will enter His kingdom rule through Israel. Representatives of these nations will be required to go up each year to Jerusalem to worship the King and learn of His ways. (Micah 4: 2)  

`And it shall come to pass that everyone who is left of all the nations which came against Jerusalem shall go up from year to year to worship the King, the Lord of Hosts, and keep the Feast of Tabernacles.` (Zech. 14: 16)
