The Cessation of God's Nation
Reborn Souls have failed.
All reborn souls aspire to act as a separate nation.
The first Christians, led by the Apostles who testified of Christ's resurrection, did so. They came out from the old humanity, lived as a nation among the nations, and restarted the process of human ripening.
Later Christians lapsed into merging with the nations they lived among, conforming to the old humanity's ways and giving little weight to whether activity-partners were reborn, except perhaps in activities that were supposed to be especially "spiritual".
The initial healthy development ceased, and no groundswell of aspiration to resume it has emerged.
God's nation ceased to function, and a nation that ceases to function ceases to be.
Why have Reborn Souls Failed?
The lapse probably occurred mainly because reborn souls were too few and scattered. (Don't ask me why God has not regenerated more; I'm just observing and drawing the obvious conclusion.)
Most of those few have been misled by prevalent false ideas, especially Otherworldalism and, more recently, Statism and Psephogynism.
Any reborn soul will support preparations for relaunch once someone has clearly enuf "explained to him the way of God more accurately" (Acts 18:26). Anyone who obstinately fails to heed this call shows that they have not been reborn.
As at 2024 I personally have come across nobody who seemed to me to be reborn. All the Christians I have encountered have been in the grip of those false ideas and have clung tenaciously to them. But I like to think that, as Elijah was told when he seemed all alone, there are "seven thousand in Israel [who] have not bowed to Baal" (1 Kings 19:18).
