The focus there was on the LAND spewing the people out. A particular land, in the Middle East, a particular context. But context is something that always gets ignored.Lev 18 where God identifies a list that HAVE caused him to "end" a nation and that WILL cause him to do it in the future.
The assumption is that because "not all other sins are listed" there - we can notice the state of certain bell weather sins to see if in fact the nation is nearing a critical crisis point.
24 'Do not defile yourselves by any of these things; for by all these the nations which I am casting out before you have become defiled.
25 'For the land has become defiled, therefore I have brought its punishment upon it, so the land has spewed out its inhabitants.
26 'But as for you, you are to keep My statutes and My judgments and shall not do any of these abominations, neither the native, nor the alien who sojourns among you
27 (for the men of the land who have been before you have done all these abominations, and the land has become defiled);
28 so that the land will not spew you out, should you defile it, as it has spewed out the nation which has been before you.
29 'For whoever does any of these abominations, those persons who do so shall be cut off from among their people.
30 'Thus you are to keep My charge, that you do not practice any of the abominable customs which have been practiced before you, so as not to defile yourselves with them; I am the LORD your God.'"
God's clear and direct statements there - suggest that we should pay attention to that list.
That was God's Holy Land, that He had set aside for His people. If other peoples obeyed His laws, they could stay; if not, they would be removed. If His own people diosobeyed, they would be removed too.
It has NOTHING to do with anywhere across whole oceans or anywhere else in the world, and neither the people who lived there before, nor the people who live there now. But just look at all the strife caused by applying this to America, it's colonzation and building, and now every disaster that occurs here.
As some sort of universal principle, it doesn't even work, as there are places that are far more immoral than America. (Holland {Amsterdam} is supposed to be really bad; Australia is known for its decadence and looseness, etc), and no one's saying they are being judged. It's all about America, and its numerous homegrown religious leaders or movements thinking they are the new Israelites or something.
