This new dispensation begins when God chooses Noah and his family to repopulate
the earth after he destroyed it with a flood.
This dispensation lasts about 406 years.
During this time, the population of the earth grew rapidly again. Noah lived 950 years total, but with each new
generation of people, the length of years decline a lot.
The people soon established a religion and
built a tower to reach unto heaven and keep men together. This wasn’t how God wanted men to live
together so he simply changed their speech and the people could not understand
one another. God knew that a dense population
of people living together was not good.
So he divided the people into the different races.
When Peleg, who was the great, great, great
grandson of Noah and the great, great, great grandfather of Abraham, was born
God divided the earth (1 Chronicles 1:19).
He was 5 generations after Noah and 5 generation before Abram. At this time the languages and races of
people were berthed and all the people separated into their very own race
across all the continents of the earth.
This dispensation finally closes after God has achieved his plan of
dispersing the people.
