One day, when the kingdom of God is realised, the desert and the desolate land of the Middle East shall become like Eden again. When that happens, the heathen that are left round about shall know that the LORD, the Holy One of Israel, has done this, Ezekiel 36:33-36 and Isaiah 41:18-20 and Isaiah 51:3-4.
“Thus saith the Lord GOD; In the day that I shall have cleansed you from all your iniquities I will also cause you to dwell in the cities, and the wastes shall be builded. And the desolate land shall be tilled, whereas it lay desolate in the sight of all that passed by. And they shall say, This land that was desolate is become like the garden of Eden; and the waste and desolate and ruined cities are become fenced, and are inhabited. Then the heathen that are left round about you shall know that I the LORD build the ruined places, and plant that that was desolate: I the LORD have spoken it, and I will do it.”
– Ezekiel 36:33-36
“I will open rivers in high places, and fountains in the midst of the valleys: I will make the wilderness a pool of water, and the dry land springs of water. I will plant in the wilderness the cedar, the shittah tree, and the myrtle, and the oil tree; I will set in the desert the fir tree, and the pine, and the box tree together: That they may see, and know, and consider, and understand together, that the hand of the LORD hath done this, and the Holy One of Israel hath created it.”
– Isaiah 41:18-20
“For the LORD shall comfort Zion: he will comfort all her waste places; and he will make her wilderness like Eden, and her desert like the garden of the LORD; joy and gladness shall be found therein, thanksgiving, and the voice of melody. Hearken unto me, my people; and give ear unto me, O my nation: for a law shall proceed from me, and I will make my judgment to rest for a light of the people.”
– Isaiah 51:3-4
Furthermore, as once a river went out of Eden to water the garden, Genesis 2:10, so shall righteousness and praise spring forth before all nations, Isaiah 61:11.
“Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else. I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear. Surely, shall one say, in the LORD have I righteousness and strength: even to him shall men come; and all that are incensed against him shall be ashamed. In the LORD shall all the seed of Israel be justified, and shall glory.”
– Isaiah 45:22-25
“And it shall come to pass in the last days, that the mountain of the LORD’S house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it. And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem.”
– Isaiah 2:2-3
“Thus saith the LORD of hosts; It shall yet come to pass, that there shall come people, and the inhabitants of many cities: And the inhabitants of one city shall go to another, saying, Let us go speedily to pray before the LORD, and to seek the LORD of hosts: I will go also. Yea, many people and strong nations shall come to seek the LORD of hosts in Jerusalem, and to pray before the LORD.”
– Zechariah 8:20-22
In the distant future, when the time comes for the new heaven and the new earth, Revelation 21, in the new Jerusalem there will be an actual river of pure, crystal clear water that proceeds out of the throne of God and of the Lamb, and nearby will be the tree of life, Revelation 22:1-2.
“And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb. In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations. And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him: And they shall see his face; and his name shall be in their foreheads. And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.”
– Revelation 22:1-5
