The thread that runs through the details of Bible is evolution.
1) A
nation believes that they are God’s chosen people and rest of the world is
pagan. When the history unfolds, the so-called chosen people go under
occupation by the so-called pagans. From this theological crisis, a new
theology of a messiah (who would restore everything) is evolved.
2) When
the Messiah did arrive, no restoration took place; rather Messiah himself was
murdered. From this evolved another
teaching that it was God’s will that Messiah should be murdered by sinners so
that sinners can seek forgiveness on the basis of such a death.
3) Even
about specific subject you can see such evolution. For example, resurrection of
Jesus. Mark was written first, and he’s hardly got anything about the
resurrection; Matthew comes next with little more information; and then toward
the end of the century we get Luke and John, and then and only then do we find
stories about Jesus eating broiled fish, cooking breakfast by the shore,
inviting Thomas to touch him, and so on..And finally book of Acts saying about
40-day works of resurrected Jesus (See, just from one-verse resurrection from first gospel of Mark to 40 days post-resurrection works in Acts)
