[Just mythoughts]

There are dispensations of time. Now what men/women have attached to what God set in motion is like adding men's traditions to the tablets set in stone.

One such example, Christ's conception was the end of a dispensation, and set in motion the opportunity for salvation. And what will end this flesh age is when the last ‘soul/spirit’ that will, comes to be born of woman. We are not told ‘when’ the souls/spirits were created, we are told that the Adam was not living until the breath of life which means soul was breathed into his nostrils. Heaven is not a soul/spirit production plant.

[Dr. Eckleburg]

I'm not really following some of your post, but I believe there are only two eras of time -- before Jesus Christ and after Jesus Christ.

Time leading up to the cross and time flowing from the cross.

Before salvation appeared and after salvation appeared.

A time of promise and a time of grace.

B.C./A.D.
