I have read several books that mention that the Hebrew/Jewish religion didn’t gain a concept of an afterlife until quite late in the game. Not sure exactly, but I think perhaps they say it was around the time of Lehi or shortly after.
I think our common conception in the church is that the idea of an afterlife was always there, from Adam on down. I’m guessing if the church were pressed on this issue, they would say that the doctrine may have been lost at certain times, but it was always true and known to the true servants of God.
My question is what is the basis for these books ascertaining that the Jews did not believe in an afterlife? Is it simply the absence of such references in the Old Testament?
