Yeah. But they've got a problem. The word they render "Dispensation" is "Okonomia" in the Greek. It means "dispensation", but not in the sense of a time period. It means "household management" with the implication of a mother in the kitchen "dispensing" nourishment to her family. From this word we get "Economy". A Country pays taxes and the Government "dispenses" of that money. That's the "Economy" of a country.
The good thing is that however God has divided the times, it is not so important what is past. What we are in and what is the next immediate AGE (aion - Gk.) is very important. There are threats and promises attached to both for the Christian. For instance, if the foolish Virgin did not buy extra oil in the age of GRACE, but must buy in the AGE of the RULE OF THE ROD OF IRON, I think it's not going to be pleasant.
