That is the problem with Johnson's claims. He is conceding to the the
claims of non-theists and saying that, if things evolved, then there was no
creator needed. This limits God's choice of how to create and neglects His
role in non-miraculous events.
Johnson is correct in noting widespread unbiblical bias in accounts of
evolution, especially in popular-level ones, but he misidentifies the point
of error. "Evolution is true, therefore I can disregard the Bible" is
wrong in the therefore. To the extent that "evolution" means the physical
process of descent from a common ancestor with modification, influenced by
natural selection, evolution is true as far as I can tell.
