Reading the Bible is complicated.
Imagine finding a trunk in an attic that’s full of letters between multiple generations of great grandparents:
It will take years to get through them all and fully understand them. You will have to study history to appreciate why the letters written during the Civil War are different from the letters written during the Great Depression.
Over time, you will get to know the people writing the letters, what they cared about, and what their issues were. You might be disturbed with them on some issues (e.g. “OMG, our great great grandparents owned SLAVES?!”).
But you will still treasure them because they tell the story of your family and how you got to where you are today, hence they give you insight into who you are. The Bible is no different.
Christians love and treasure the Bible. It can inform, inspire, and guide us, even though we don’t necessarily agree with our ancestors in all things.
The Bible is not simple black and white. It has multiple views on abortion, marriage, slavery, the afterlife, God, Satan, etc, because the Bible is not a book, but a trunk of letters.
