"Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption."
The children sat in the pews, in unchildlike rapt attention, listening to Reverend Pete delivering his lesson.
"Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed."
This was in fact a history lesson. They, the children themselves, were the incorruptibly raised great-great-great-great-great-ad-nauseum grandparents of the teachers. The children were closely monitored, not just by cameras, but by sensors in their bodies reading their very thoughts. The teachers were making sure there was no sin in their new world. Reverend Pete's jewel-encrusted trumpet sat on a pedestal next to the lectern.
"For this corruptible must put on incorruption, and this mortal must put on immortality."
Jason, apparently 9, had clear memories of his past life. Always had. In computer memory, directly accessible inside his head. More like a little Wikipedia entry, really. "Jason Burch was born in 1872, worked as a farm laborer at ages 20 and 30, but then later worked at Garver's General Store as a furniture salesman. He married Martha Anderson and had children Benjamin, Louise, and Sarah, and died in 1943." With links and pictures. He'd been cremated, but his DNA had been deduced from his descendants, with reasonable guesses filling in any gaps. His wife Martha, also 9, sat in the pew next to him. His son Benjamin appeared 10.
"So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory."
Yes he had died. Yes he was alive. Yes he was in "New Jerusalem", a space habitat in the asteroid belt. Yes he was now incorruptible, immune to age, disease, and injury. He could even be rebuilt from backup if his body were destroyed.
Did Jason believe in God? in Jesus? Actually yes he did, always had, and he still approved. But Reverend Pete and his new world here were a fake. Even the teachers' intrusive control was a facade. Yes he could think in his meat brain and it would be monitored. But he could also think in his built-in computer and message the other children wireless and encrypted. So he did, while his meat brain thought pure thoughts.
"O death, where is thy sting? O grave, where is thy victory? The sting of death is sin; and the strength of sin is the law."
[This is no "end days",] Jason messaged to Martha. [We weren't resurrected by God. We were resurrected by technology. There's no Jesus physically here. Only Reverend Pete.]
[What a pompous ass,] she messaged back. [We'll jailbreak this hellhole as soon as we figure out how.]

The point of the story is, in the next few hundred years, a surprising number of Christian prophecies will be fillable in letter, though not in spirit, by technology. And some unfortunate soul (probably multiple) will believe they are the Hand of God fulfilling these prophecies by applying that technology. Including raising the dead. The "raised" will not be fooled, and will not play along. Another one of those prophecies is "the old earth shall pass away", so the earth military will take a very dim view to any such Hands of God trying to checkmark all those prophecies.
