One can read everything has been written about Brahman...listen to every lecture by every sage...and still remain in ignorance of the nature of Brahman. Brahman isn't attainable through thought, so it is verily beyond the reach of thought.
God may be many things, but one thing he is not: He is not going to protect us from our mistakes.
These are the kinds of ideas that lead me to believe that thought about gods and ultimate reality and participation in a religion as well as the relatively fruitlessness of my prior efforts there aren't productive use of time. I really don't know what either of your get out of that. I also have no concept of Brahman nor look to gods for protection, but that leads me away from religious activity.
You're both intelligent, mindful, and decent people, and I like to think that I am as well, also seeking truth and goodness. But I find no value in theism, religion, or religious contemplation. There has been nothing of value for me there, and so it's no longer a part of my life. I wonder why that is.
Bible is not like that. I don't understand how some can claim it is, even though they can't prove it.
The Bible IS like that, but you can't see it due to a faith-based confirmation bias. You believe a priori that the Bible is the flawless word of a tri-omni deity, and so that's what you see. I see all kinds of internal contradiction, scientific and historical error which believers will call anything but that, and intellectual and moral errors attributed to what is called a tri-omni god.
I would offer it is the arrogance of man that they would reject the Word given of God, for any petty reason they choose to do so.
What's arrogant is for you to expect people to follow you and to call them arrogant for refusing to do so.
It is arrogant of you to think that your scriptures come from a deity and diminish others for disagreeing (arrogant, petty) when they're words most of literate humanity could have written.
My reason to reject your claims about your scriptures is not petty. Skepticism, or the willingness to challenge claims and to require more than just claims before believing, is one of the greatest ideas man has ever had. It alone frees us from the tyranny of superstition. It transformed astrology and alchemy into astronomy and chemistry. It transformed creationism into modern biology and cosmology. It transformed ossified, received morals into rational ethics.
