I have no complaint with the Bible. I just don't consider it a source of knowledge or wisdom. Its myths and prophecies have no application in my life, and its moral imperatives reflect an ancient people's problems and don't address many modern moral precepts.
Please elaborate on this because I found just the opposite especially Proverbs for Wisdom, I found these to be timeless truths as well as for practical living.
If you found guidance in those passages, then they were helpful to you.
My definition of a truth is something that can be shown to be correct. Most statements in the Bible don't meet that requirement, and one need not consult holy books to find the ones they contain those that do. So, yes, the Golden Rule is a timeless moral imperative for me and many others, but I didn't get that insight from the Bible. How could I? It only gives instructions to obey it beside many other instructions that turn out to be of no value. One has to learn which of these ideas resonates with his own conscience empirically. The intuitions of the conscience and life's lessons resulting from both obeying and defying that intuition are the teacher, not any book.
Were you asking only about that first sentence, or both? I'll answer as if both.
I find no value in myths. I suppose it was a reasonable way to codify and transmit common cultural values and generate a sense of community in the days when people had very little education and simple stores were ways to teach.
Nor in prophecy. I find nothing helpful there.
And the Bible is no longer applicable as a moral authority or a good source for moral guidance. The world has changed too much. The Bible contains moral commandments that I consider immoral, and it fails to address the issues of the modern world, where slavery is considered immoral, freedom of and from religion are considered rights, homosexuality and atheism are morally neutral rather than sins of abominations, and democracy is preferred to authoritarian governments.
Once again, none of these are complaints about the Bible. It's fine like it is to me, but is not a resource. As I alluded, that which I call knowledge and wisdom is acquired empirically, by trial-and-error. This is how I have decided which ideas accurately represent the world and can be used to predict outcomes to facilitate that which facilitate contentment. This is how I have discovered what love is, how to love others, and how to decide who loves back and who is just saying the words with no idea of what they should mean. It's how I learned to treat others - empirically, not from Proverbs in my case. One makes mistakes, the conscience punished him, and he modifies his behavior in the future accordingly to facilitate a better outcome next time.
I hope this answers your question.
