On to the New Testament:
"Because Christ also died once for our sins, the just for the unjust: that he might offer us to God, being put to death indeed in the flesh, but enlivened in the spirit, [19] In which also coming he preached to those spirits that were in prison: [20] Which had been some time incredulous, when they waited for the patience of God in the days of Noe..."
"And when he had opened the book, the four living creatures, and the four and twenty ancients fell down before the Lamb, having every one of them harps, and golden vials full of odours, which are the prayers of saints"
You take that to mean . . . what?
Daniel 12:2
Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt.
