"Be not afraid, O land; be glad and rejoice. Surely the Lord has done great things. Be not afraid, O wild animals, for the open pastures are becoming green. The trees are bearing their fruit; the fig tree and the vine yield their riches." NIV translation
There has been and will continue to be famines and drought but they are all temporary. When our hearts are changed and turned back to the Lord, He will take care of us both now and forever.
"Be glad, O people of Zion, rejoice in the Lord your God, for he has given you the autumn rains in righteousness. He sends you abundant showers, both autumn and spring rains, as before." NIV translation
In the land of Israel, the majority of rain falls between October and April. Although the land is very dry today, we see that, during this millennial reign, the rains will be plentiful once again.
"The threshing floors will be filled with grain; the vats will overflow with new wine and oil." NIV translation
This return of the rains will allow the crops to grow in abundance. We see that they are not merely enough to survive but in fact are overflowing. This is a fulfillment of the promise that was given through the prophet Malachi when God told His people to trust Him by bringing in the tithes of the crops (see Malachi 3).
"'I will repay you for the years the locusts have eaten - the great locust and the young locust, the other locusts and the locust swarm - my great army that I sent among you. You will have plenty to eat, until you are full, and you will praise the name of the Lord your God, who has worked wonders for you; never again will my people be shamed.'" NIV translation
This abundance will more than make up for the years that the land suffered desolation. We notice that, once again, this speaks of a time after the tribulation that is to come. This thousand years will be a time of plenty as men praise and worship the Lord again in Jerusalem.
