Olam Ha-Ba 

The world after the messiah comes is often referred to in Jewish literature as Olam Ha-Ba (oh-LAHM hah-BAH), the World to Come. This term can cause some confusion, because it is also used to refer to a spiritual afterlife. In English, we commonly use the term "messianic age" to refer specifically to the time of the messiah. 

Olam Ha-Ba will be characterized by the peaceful co-existence of all people (Isaiah 2:4). Hatred, intolerance and war will cease to exist.

2 And it shall be at the end of the days, that the mountain of the Lord's house shall be firmly established at the top of the mountains, and it shall be raised above the hills, and all the nations shall stream to it.

All of the Jewish people will return from their exile among the nations to their home in Israel.

(Isaiah 11)

11 And it shall come to pass that on that day, the Lord shall continue to apply His hand a second time to acquire the rest of His people, that will remain from Assyria and from Egypt and from Pathros and from Cush and from Elam and from Sumeria and from Hamath and from the islands of the sea.

12 And He shall raise a banner to the nations, and He shall gather the lost of Israel, and the scattered ones of Judah He shall gather from the four corners of the earth.

(Jeremiah 23)

1 Woe to the shepherds who destroy and scatter the flocks of My pasture! says the Lord.

2 Therefore, so says the Lord God of Israel concerning the shepherds: You who pasture My people, you have scattered My flocks and have driven them away and have not taken care of them; behold, I will visit upon you the evil of your deeds, says the Lord.

3 And I will gather the remnant of My flocks from all the lands where I have driven them, and I will restore them to their dwellings and they shall be fruitful and multiply.

4 And I will set up shepherds over them and they shall pasture them, and they shall no longer fear nor shall they be dismayed, nor shall [any of them] be missing, says the Lord.

5 Behold, days are coming, says the Lord, when I will set up of David a righteous shoot, and he shall reign a king and prosper, and he shall perform judgment and righteousness in the land.

6 In his days, Judah shall be saved and Israel shall dwell safely, and this is his name that he shall be called, The Lord is our righteousness.

7 Therefore, behold days are coming, says the Lord, when they shall no longer say, "As the Lord lives, Who brought up the children of Israel from the land of Egypt,"

8 But, "As the Lord lives, Who brought up and Who brought the seed of the house of Israel from the northland and from all the lands where I have driven them, and they shall dwell on their land."

This started in 1948 with the modern state of Israel, but many of the flock is still scattered. I hope soon to join my flock in Israel.

(Jeremiah 30)

3 For, behold, days are coming, says the Lord, when I will restore the captivity of My people Israel and Judah, says the Lord, and I will restore them to the land that I gave their forefathers and they shall possess it.

(Hosea 3)

4 For the children of Israel shall remain for many days, having neither king, nor prince, nor sacrifice, nor pillar, nor ephod nor teraphim.

5 Afterwards shall the children of Israel return, and seek the Lord their God and David their king, and they shall come trembling to the Lord and to His goodness at the end of days.

In the Olam Ha-Ba, the whole world will recognize Hashem as the only true G-d.

(Micah 4)

1 And it shall be at the end of the days, that the mountain of the Lord's house shall be firmly established at the top of the mountains, and it shall be raised above the hills, and peoples shall stream upon it.

2 And many nations shall go, and they shall say, "Come, let us go up to the Lord's mount and to the house of the God of Jacob, and let Him teach us of His ways, and we will go in His paths," for out of Zion shall the Torah come forth, and the word of the Lord from Jerusalem.

There will be no murder, robbery, competition or jealousy. There will be no sin

(Zephaniah 3)

13 The remnant of Israel shall neither commit injustice nor speak lies; neither shall deceitful speech be found in their mouth, for they shall graze and lie down, with no one to cause them to shudder. 

Some gentiles have tried to put an ugly spin on this theology, claiming that Jews plan to force people to convert to our religion, perhaps based on their own religion's history of doing exactly the same thing. That is not at all how Jews understand the messianic age. We believe that in that future time, everyone will simply know what the truth is, in the same way that we know that 2+2=4, and there will no longer be any reason to argue about it. When mashiach comes, theological truths will be equally obvious to mankind, and there will be no reason to argue about it
