To understand why the increase of global homogenization is a bad thing, we must understand why YHVH God hindered Noah's early offspring from continuing with their projects at Babel, in the plains of Shinar. At first glance, it seems as bit mean, even tyrannical. What was so bad about people working together to build an advanced civilization?
Unity can be a very good thing in the right contexts, so no one can be blamed for imagining that a united world might be for the best. In order to achieve the right perspective on this matter, we have to first acknowledge that YHVH is eternally and immutably good, and always acts in the best interest of his Creation (insofar as he is permitted by the Grand Law of the Cosmos and legal battle that is raging in the spirit realm). The entire Bible reveals the loving nature of the Creator, and that Word is the best testimony to his character. He is also a just judge, yes, but an unspeakably loving one who delights in showing mercy to those who repent of evil. The Four Gospels reveal just how incomprehensibly kind God has been to us humans: he sacrificed the most valuable thing in the universe in order to rescue us from the fate of eternal death. Once we understand that reality, we can dispense with the notion that God divided the people at Babel because he's some sort of bully.
YHVH had two very good reasons for interfering at Babel: 1. The people were rebelling against his explicit command; 2. They were a threat to themselves (and possibly to structure of the cosmos itself, but I won't get into that in this post).
After the Flood, God blessed Noah and commanded he and his descendants to be fruitful and multiply throughout the earth (Gen. 9:1, 7). He didn't want lots of people dwelling together in one spot. There are a lot of reasons why that might be, but one of the biggest reasons is that the land can't support it. The good life—the life God intended for us—is one wherein each family has its own land to farm or ranch, and they are sovereign over that land. The earth provides what is needed, so no one is in want or enslaved to debtors. Small towns and villages are probably also allowable, so long as the population is small enough that everyone more-or-less knows one another, because being known breeds a level of patience, empathy, and cooperation that is lacking among the nameless masses.
In this kind of scenario, damage is mitigated. When things go sour, the detrimental effects are fairly localized. Not so in large population centers. Huge numbers of people can be negatively affected by the sins of a few. Power becomes centralized, and, since the human heart is hopelessly twisted (Jer. 17:9), the wicked will always claw their way into those limited positions of power. Improper governance inevitably follows. Furthermore, cities are breeding grounds for poverty, disease, stratification into classes, and other such tragedies. God knew this, and wished to spare humankind unnecessary suffering. But the people wouldn't obey him. We read in the Genesis account:
The whole earth was of one language and of one speech.... They said, "Come , let's build ourselves a city, and a tower whose top is in the heavens, and let's make a name for ourselves, lest we be scattered abroad on the surface of the whole earth" (Gen. 11:1, 4).
But that wasn't the only issue. God foresaw that as their numbers increased, so too would their abilities, until they reached a place of super advanced technology. In fact, so long as they cooperated, they would be able to accomplish anything. To wit:
And the LORD said, "Behold, the people are united, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do" (Gen 11:6).
Would you hand your toddler a loaded gun? Of course not, because know that she could hurt herself. Adult human beings aren't much more trustworthy than that toddler; we always end up blasting somebody or other. God, in his love, would rather we didn't have powerful tools with which to kill and oppress each other.
Yet here we are, once again cooperating in large numbers and, as a result, developing instruments which we have no business wielding. Think about merely the most obvious of the problematic technologies. We've harnessed the power of the atom. Yay, us. Now we can destroy entire civilizations with the push of a button, and mar the face of the earth beyond recognition. All it takes is a brief fit of madness to make that scenario a reality. But we haven't stopped there, no—we're almost at the point where we can alter the very programming code of our bodies and permanently corrupt the image of God. Who can even imagine all the implications of turning ourselves into something that's no longer human? I could go on and on discussing the potential nightmares that could arise from developments like artificial intelligence, nanobots, weaponized germs, and the like.
YHVH divided man's language in order to slow down progress and force us to spread out. It worked exactly as he intended. Unfortunately, in the thousands of years that have since elapsed, mankind has not learned its collective lesson. We're still in rebellion. Organizations like the WEF, the United Nations, and many others, are working tirelessly to reverse the fall of Babel and bring us back under a single ruling authority which they dub The New World Order.
Will they succeed? Unfortunately, yes. Bible prophecy guarantees it (see Revelation 13, 17,and 18). God's people, however should have nothing to do with this return to Babel (and the Beast Kingdom that will be married to it), but rather teach and pray against the New World Order. We ought to be raising a ruckus and making secularists hate us because we are exposing the godlessness of globalism. Perhaps we can slow down the inevitable; but even if we can't, we will have shown clearly whose side we're on, and thus receive a reward from Almighty God at the Judgement.
