Death is a sin!

Indeed it is the last sin to be abolished by God.

WHAT is “Second Death”?

Simply put it’s the cessation of life a second time.

All must die one time, but some are destined to die twice..

WHO  are subject to a “second death”?

Those who’s names are not in the Book of Life

WHY

Because they have been found wanting.

 However that is to be determined God  knows.

So thst they may be  cleansed and later return to life, God-spirited.

WHAT occurs at death is  that the spirit goes direct to God, the body disintegrates and the soul passes into the unseen.

 The victims return to God and are resurrected (vivified), following what would feel like a *short sleep,  when “death”is abolished and God is all in all.

HOW does “Second Death” occur??

The victims are cast into the lake of fire

This is not a torturous death, there is no pain involved and life is snuffed out instantaneously.

This happens, WHEN judgement  is rendered by our Lord Jesus Christ at the Great White Throne..paulnbob

*Paul tells us what happens and what those who are in repose awaiting the "call", when he says in ! Corinthians, "Lo, I will tell you a mystery. ...we shall all be changed, in a moment, in a twinkling of an eye...will  be raised imperishable..."

This a rather cursory explanation, for one in much greater depth, I refer you to the Concordasnt Publishing Concern website.
