Note slightly altered order for clarity. You provided three responses. I felt it was easier to deal with your middle response first.
Since God now exists we primarily need to examine his revelation to us to determine his relationship to us and the rest of his creation. There are two kinds revelation, general and special. I'll spare you the long lecture about them and assume you already know what they are and how they relate to one another.
Revelations are a dime a dozen. Millions of people are convinced they had one or more of them. Unless they can be tested empirically, they are just so many "inner voices". There are no tests to distinguish the inner voices of a schizophrenic paranoic from an inner voice that turns out to be the voice of God. Until there is such a test, any argument based on revelation is of no interest to me.
Two issues here. Which revelation and how do you test it.
First. Since God exists who cares about human revelation. If God created us for a purpose then we have a purpose....plain and simple. If God does not exist then naturally we don't have an objective purpose. To each his own governed some by group dynamics to thrive.
Second. Of course they're testable. It is our epistemic duty to seek the truth and dispel falsehoods. Our worldviews are shaped by this duty. A revelation would be as testable as any worldview. It must be logically consistent, empirically adequate and existentially relevant. Which means its teachings cannot be self-contradictory, must match what we see in reality and must speak directly to how we actually live our lives.
Make sense?
But in order to begin address the all of your seemingly sincere concerns, you need to understand something major that is implicated in that concession. You and the universe did not have to be created. That implies that a personal eternal creator had a choice to create. Which means he had a reason/purpose to create you and the universe. Thus the objective purpose and meaning for our lives must logically be the reason he had to create us. Not some subjective purpose of our own creation, but actually the purpose he had for creating us. Good so far?
Note my questions above carefully. Because hidden in the implications of your concession is the answer to what is the purpose and meaning for this live. Agree or disagree?
Now I'll quickly throw in another implication here as well. You are possibly questioning well there are so many God's that we have to choose from.....so which one and which purpose? Still seems pretty subjective right? Not really. Only theism fits the description of the concession. Atheism for sure is out. All the other polytheistic God's are part of the universe, so rationally only theism fits the concession. Thus all that remains in the realm of possibility are the Abrahamic Theisms. Put very simply "for now" they pretty much share the same purpose for life. To know God and make him known. Is this implication clear so far?
OK, you seem to be touching on two aspects, the meaning of life and morals I asked you about earlier. My questions about them were: What are they, and how do we know? In short, I want evidence. Specifically testable evidence. Will there be a time when you'll actually provide an answer them instead of beating about the bush?
Please examine carefully. I copied in my full quote to you and bold faced the only part you actually quoted to show you I had answered your question. The underline part was the answer to your question. Right there in the part you did not quote. Granted I was addressing this in a general sense because you weren't being very specific. Again from above the purpose of life and the moral code rest upon his revelation.
Now I have two issues for you.....
You're insinuating that all knowledge must rest on empirical evidence.
That is a philosophical position. More precisely, it is an epistemology commonly known as empiricism.
Can you please provide some empirical evidence that empiricism is the best epistemology?
with follow the up..............
How do you test "the purpose of life" empirically?
So, here is your mission, should you choose to accept it: Assuming the existence of a spaceless, timeless and immaterial creator of everything, how does that affect our understanding of the universe? How can we discover how we should then live our lives? It's a repeat of what I asked in post #58, but put in other words in the hope that you will understand the question
How does it affect our understanding of the universe? That would depend on what you are trying to understand.
Evasions noted. Stop that. Just answer the question
I have asked you the same questions often enough now. "It depends" is a non-answer. Frankly, it seems to me that you just don't know.
I'm not evading. I just can't read your mind...........
I've certainly addressed the issue of purpose, because that is pretty narrow in scope.
But examine your question about understanding the universe.
It is wide open.
Are the nature of concerns concerns scientific, metaphysical, theological, anthropomorphical, eschatological, philosophical, etc.
Do you want to understand a HOW.....WHY.....WHAT........WHERE.......WHEN........IF ?????
About what....galaxies, love, free will, cosmology, evil, star formation ?????
Do you want to understand how is works? Do you want to understand the why the universe is comprehensible? Do you want the understand when it actually began to exist?
Or are you using the term "universe" not as a whole but a variable for any part of the universe.....Do you want to understand how stars are formed? Do you want understand where the fundamental constants of nature came from? Do you want to understand the fundamental nature of particles? Do numbers exist?
Or are you asking of more spiritual concerns ....Do you want to understand the how the universe declares the glory of God? Do you want to understand why "it" was made? If evil exists why God?
Comparative understandings What came first the self-replication cell or DNA? Mind-body dualism? material vs immaterial. Good vs evil. particle or wave? cosmological models reflecting a finite past vs an eternal past? Logic vs logos. Mind over matter?
enough????
And here is the punch line.....Now how does knowing that God exists affect all of those different understandings?
It would logically range from NONE...........to..........ALL,
BECAUSE IT LOGICALLY DEPENDS ON WHAT YOU ARE TRYING TO UNDERSTAND!
Understand?
