Somewhat agree, but no, not "if we all followed the Bible", only if we followed certain parts that have valid teachings. Not a blanket generalized statement as just the "Bible" implying "all" of the Bible.
The bible isn't a whole, holistic, non-contradictory, fully consistent, united work. It has contradictions. It is disunited. It has examples that preach of good as objectively good, and examples of preaching evil as subjective illusory images of "good". Like any book, a reader needs to have critical thinking and a developed capacity for discernment, not blind belief and acceptance of everything in a book.
Just making that clear. I have gained much value from certain parts of the Bible, not all of the Bible. I will be doing a post on some teachings in the future to show some of the value in the teachings of older times, like the Bible.
Peace.
