Well, I've got some answers of my own. They are Old Testament, but Deutero-Canonical.
It depends on how you regar"Wisdom". or Wisdom of Solomon, an Alexandrian composition probably predating Philo and drawing from Septuagint texts.
From Chapter 2:
There is a discussion of life as the godless see it and how the believer should be tested and put to torture to see if God will intervene. In answer:
23. For God created human beings to be immortal, he made them as an image of his own nature, Death came into the world only through the Devil's envy, as those who belong to him find to their own cost.
From Chapter 3:
1. But the souls of the upright are in the hands of God, and no torment can touch them.
2. To the unenlightened they appear to die, their departure was regarded as a disaster,
3. their leaving us like an annihilation, but they are at peace.
4. If, as it seemed to us, they suffered punishment, their hope was rich with immortality. slight was their correction, great will their blessings be.
God was putting them to the test and has proved them worthy to be with him; he has tested them like gold in a furnace and accepted them as a pefect burnt offering.
...
10. But the godless will be duly punished for their punished for their reasoning ...

I open the floor to comments on this one. But it looks to me like the Deutero-Canonical explains New Testament concepts better than the canonical Old Testament. This is an Alexandrian/Hellenic/Jewish outlook not far afield from that of Paul and perhaps one or two of the Gospel writers. It also puts the description of Josephus of the Essenes in perspective.
