The Tower of Babel
Genesis 11:-9 | NIV

1 Now the whole world had one language and a common speech.
2 As people moved eastward, they found a plain in Shinar and settled there.
3 They said to each other, “Come, let’s make bricks and bake them thoroughly.” They used brick instead of stone, and tar for mortar.
4 Then they said, “Come, let us build ourselves a city, with a tower that reaches to the heavens, so that we may make a name for ourselves; otherwise we will be scattered over the face of the whole earth.”
5 But the Lord came down to see the city and the tower the people were building.
6 The Lord said, “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them.
7 Come, let us go down and confuse their language so they will not understand each other.”
8 So the Lord scattered them from there over all the earth, and they stopped building the city.
9 That is why it was called Babel—because there the Lord confused the language of the whole world. From there the Lord scattered them over the face of the whole earth.

Going by the above verses in the bible, the major cause of division in the world is the biblical God fueled by his own insecurity.

Is it not then counterproductive to pray to this same God for the promotion of unity amongst mankind?

It is indeed counterproductive to pray to the same God for the promotion of the kind of unity that mankind seeks since He has never expressed interest in that which mankind thinks of says that it desires. Rather, He did make abundantly clear what His goal and plan are in the pages of Scripture. Of course, men remain uninterested in any of what He has said. Their delusions remain their priorities to date.
