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:Amos 8:11
And the seven years of dearth began to come, according as Joseph had said: and the dearth was in all lands; but in all the land of Egypt there was bread.And when all the land of Egypt was famished, the people cried to Pharaoh for bread: and Pharaoh said unto all the Egyptians, Go unto Joseph; what he saith to you, do.And the famine was over all the face of the earth: and Joseph opened all the storehouses, and sold unto the Egyptians; and the famine waxed sore in the land of Egypt.Gen 41:54-56
And he said, Behold, I have heard that there is corn in Egypt: get you down thither, and buy for us from thence; that we may live, and not die.Gen 42:2
And God sent me before you to preserve you a posterity in the earth, and to save your lives by a great deliverance.Gen 45:7
There is currently a spiritual famine (Lack of spiritual food:God's Word) on earth and just as it was in the days of old, God has raised His Joseph's to store up food (His Word) to preserve and sustain all those that fear Him.
Only those who 'go down'(make efforts) to seek and eat the food that the End time Joseph's have on offer will survive the Famine. All those who reject the food on offer will Perish.
