Once we make this connection in our minds, then this symbolic type of water or rain begins to present itself not only in the Book of Isaiah, but throughout the rest of the Bible as well. It becomes such a dominant theme that we can no longer ignore it, even if we try.
1 GIVE ear, O ye heavens, and I will speak; and hear, O earth, the words of my mouth.
2 My doctrine shall drop as the rain, my speech shall distil as the dew, as the small rain upon the tender herb, and as the showers upon the grass:
Likewise, other prophets besides Isaiah predict the cessation of revelation through prophets. They do this using water and rain as a symbolic type as found in Isaiah.
1 THE word of the LORD that came to Jeremiah concerning the dearth.
2 Judah mourneth, and the gates thereof languish; they are black unto the ground; and the cry of Jerusalem is gone up.
3 And their nobles have sent their little ones to the waters: they came to the pits, and found no water; they returned with their vessels empty; they were ashamed and confounded, and covered their heads.
4 Because the ground is chapt, for there was no rain in the earth, the plowmen were ashamed, they covered their heads.
Here the prophet Jeremiah makes the same prophecy as found in the Book of Isaiah. The future generations of the children of Israel will seek revelation and not find it. “They came to the pits, and found no water.” Hence, “the ground is chapt, for there was no rain in the earth.” The children of God seek revelation from God and seek for the Lord’s servants the prophets, but there is no revelation and there are no prophets. The prophet Amos, likewise, reiterates this prediction of prophetic dearth or drought.
11 ¶ Behold, the days come, saith the Lord GOD, that I will send a famine in the land, not a famine of bread, nor a thirst for water, but of hearing the words of the LORD:
12 And they shall wander from sea to sea, and from the north even to the east, they shall run to and fro to seek the word of the LORD, and shall not find it.
Again, water and rain are used to mean “hearing the words of the LORD” or in other words revelation through prophets. We see from the prophet Amos that the children of the earth will wander around seeking the word of the LORD, “and shall not find it.” I believe this concept of spiritual famine should now be well documented. But what about the Latter Rain? When will this spiritual famine of hearing the words of the LORD cease?
Isaiah describes the idea of a restoration in the last days. And this concept of restoration is repeated throughout the Bible.
4 Say to them that are of a fearful heart, Be strong, fear not: behold, your God will come with vengeance, even God with a recompence; he will come and save you.
5 Then the eyes of the blind shall be opened, and the ears of the deaf shall be unstopped.
6 Then shall the lame man leap as an hart, and the tongue of the dumb sing: for in the wilderness shall waters break out, and streams in the desert.
7 And the parched ground shall become a pool, and the thirsty land springs of water: in the habitation of dragons, where each lay, shall be grass with reeds and rushes.
8 And an highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err therein.
In the last days, the prophet Isaiah predicts a time when this terrible spiritual drought will end, and prophets will once again be called upon the earth. The rain of revelation these modern-day prophets receive will help create a sure path for those living on the earth. Though fools, they shall not err therein. Latter-day Saints recognize the beginning of this Latter Rain period as starting with Joseph Smith and his first vision in the Sacred Grove of Palmyra, New York.
