God's Judgment on Nations
Because Israel -- like other countries throughout history -- rejected His truth, worshipped other gods and attacked God's faithful and uncompromising remnant, it would face God's judgment. The natural, social and political consequences would devastate the proud and powerful nation. The same could happen to America. See 1 Corinthians 10:1-13
Leviticus 26
If you walk in My statutes and keep My commandments, and perform them, then I will give you rain in its season, the land shall yield its produce, and the trees of the field shall yield their fruit. Your threshing shall last till the time of vintage, and the vintage shall last till the time of sowing; you shall eat your bread to the full, and dwell in your land safely.
I will give peace in the land, and you shall lie down, and none will make you afraid; I will rid the land of evil beasts, and the sword will not go through your land. You will chase your enemies, and they shall fall....
For I will look on you favorably and make you fruitful, multiply you and confirm My covenant with you. You shall eat the old harvest, and clear out the old because of the new. I will set My tabernacle among you, and My soul shall not abhor you. I will walk among you and be your God, and you shall be My people." Leviticus 26:3-12
But if you do not obey Me, and do not observe all these commandments, and if you despise My statutes, or if your soul abhors My judgments, so that you do not perform all My commandments, but break My covenant, I also will do this to you: I will even appoint terror over you, wasting disease and fever which shall consume the eyes and cause sorrow of heart. And you shall sow your seed in vain, for your enemies shall eat it.
I will set My face against you, and you shall be defeated by your enemies. Those who hate you shall reign over you, and you shall flee when no one pursues you. And after all this, if you do not obey Me, then I will punish you seven times more for your sins. I will break the pride of your power; I will make your heavens like iron and your earth like bronze. And your strength shall be spent in vain; for your land shall not yield its produce, nor shall the trees of the land yield their fruit.
Then, if you walk contrary to Me, and are not willing to obey Me, I will bring on you seven times more plagues, according to your sins. I will also send wild beasts among you, which shall rob you of your children, destroy your livestock, and make you few in number; and your highways shall be desolate.
And if by these things you are not reformed by Me, but walk contrary to Me, then I also will walk contrary to you, and I will punish you yet seven times for your sins. And I will bring a sword against you that will execute the vengeance of the covenant; when you are gathered together within your cities I will send pestilence among you; and you shall be delivered into the hand of the enemy. When I have cut off your supply of bread... you shall eat and not be satisfied." Leviticus 26:14-26
But if they confess their iniquity and the iniquity of their fathers, with their unfaithfulness in which they were unfaithful to Me, and that they also have walked contrary to Me, and that I also have walked contrary to them and have brought them into the land of their enemies; if their uncircumcised hearts are humbled, and they accept their guilt then I will remember My covenant with Jacob, and My covenant with Isaac and My covenant with Abraham I will remember; I will remember the land." Leviticus 26:40-42
Since those Old Testament times, atonement for sins and eternal life with Jesus has been made available to everyone through the cross. See What it means to be a Christian
