God deals with humanity and the nations according to their generations

God rates, examines and numbers humanity according to their generations; to God every human belongs to a generation. He groups all mankind according to generation and deals with them accordingly.

Every individual, family, business, ethnicity, community, town, city, society, people, nation and country is founded and built on layers of generation past and present. As human beings each one of us belongs to a generation in the world. The moment you were born into the world you were logged into a generation in heaven and on earth. God keeps account of your spiritual generation ID and the government and your family keeps accounts of your physical generational ID.  If you ever hear of the word born free Generation, it refers to all those people born in South Africa after the fall of apartheid and the liberation. There a different types of generation in the world today, every society or country has between 3- 7 generations living at the same time.
