Claim. God began the providence of resurrection in Adam’s family, but the failures of those entrusted prolonged the work. The 2000 biblical years from Adam to Abraham established the foundational indemnity conditions on which God could then begin the providence proper — making this an age of foundation-laying for resurrection, not yet an age of resurrection itself.
Elaboration. Per 2.2.1. The Providence to Lay the Foundation for Resurrection: “God began His providence to resurrect fallen humankind in Adam’s family. However, the providence was prolonged because those who were entrusted with accomplishing God’s Will did not fulfill their responsibilities. Two thousand biblical years later, God chose Abraham to be the father of faith, and through him God’s Will began to be accomplished.”
Doctrinal status of this period: a pre-providential prelude. The Adam-to-Abraham era did not itself resurrect anyone to a defined spirit-stage. Rather, it established — through a long series of indemnity-conditions, partial successes, and partial failures — the foundation on which God could commence the formation-stage providence with Abraham. This is the first concrete instance of the merit-of-the-age mechanism: even a 2000-year period of largely-failed work broadens the foundation.
DP’s anthropology of this age: people lived without Law, without Messiah, without organized priesthood. There was no defined justification path. The spiritual fate of pre-Abrahamic individuals (Noah, Enoch, Job, the patriarchs of Genesis 4-11) is left underspecified in Ch 5 — Part II Chapters 1-3 develop the Noah-and-the-restorative-conditions narrative in detail.
This atomic distinguishes the four-stage providential history (foundation + formation + growth + completion) from the three spirit-stage ages (formation/growth/completion). The Adam-to-Abraham period is a precondition, not one of the three providential stages.
