An atheist writer I enjoy draws a distinction between those who make their way through rational analysis of objective evidence, versus those who make their way reading the Bible. I don’t draw that distinction at all.
Biblical scriptures work. They are effective at capturing the truth of the spiritual conditions we all face and mapping the way forward, particularly when that way is contrary to the leadings of our deceived and deceitful hearts. This very effectiveness is part of the way these documents came to be recognized as scripture (a process that took a long time).
Reading the Bible thus broadens the scope of reliable input. For those who make their way through rational analysis, attention to scripture expands the range of evidence that this analysis can put to use.
