Hi, Mark -
A fairly exhaustive discussion of this
question appears in C.S. Lovett's "Latest
Word on the Last Days". In short, and based on
scripture, Lovett concludes that there will be no salvation after the
Men living in the millenium will
experience 1000 years of enforced righteousness, a kingdom wherein is no sin, no
corruption, no pollution. However, these men will have been born with the
self-centered Adamic nature, and when Satan is released at the end, his appeals
will resonate with those fallen natures. After a short-lived rebellion,
all will be cast into the Lake of Fire.
I discussed this at some length on my
Friday program, linked below. Hope this helps.
