Desert is a desolate, dry and deserted land. Deserts take up about one third (33%) of the Earth's land surface. Oases are often the only places in deserts that support crops and permanent habitation.
When Christ reigns in His Kingdom for 1,000 years, the deserts will become fertile fields and the fields will become as forests.
“The wilderness and the dry land shall be glad; and the desert shall rejoice, and blossom as the rose.”
“The LORD will surely comfort Zion and will look with compassion on all her ruins; he will make her deserts like Eden, her wastelands like the garden of the LORD(Ὡς παράδεισον κυρίου Hōs paradeison kuriou – literally 'As the paradise of the Lord.'). Joy and gladness will be found in her, thanksgiving and the sound of singing.”
Judea is here represented as lying waste. It is to be remembered that the time to which the prophet here refers is that of the captivity in Babylon, and near its close. Of course, as that would have continued seventy years, in so long a period Judea would have become almost an extended wilderness, a wide waste.
“ They will say, ‘This land that was laid waste has become like the garden of Eden; the cities that were lying in ruins, desolate and destroyed, are now fortified and inhabited.’”
If God had raised up so great a nation from so humble all origin, he had power to restore the waste places of Judea to more than their former beauty and prosperity. When Christ restores the waste places of Israel, He will restore the deserts in the entire world as like the Garden of Eden, I believe.
