That is the last thing I want to do.
Good to hear.
"If the essence of God is unknowable, then belief in God without that knowledge is justifiable."
It is justifiable because it is unreasonable to expect to know what we cannot know.
If you can't know that God exists, then believing in God is unjustified. This is still true even if it's impossible to know that God exists.
It is also justifiable because we do not need to know the essence of God in order to believe in God.
If we had needed to know that God would have revealed it to us.
Also, humans would never be able to comprehend the essence of God, so why would God reveal that to us?
Begging the question.
Spoken like a true atheist...
Are you assuming that if God existed God would be observable and measurable?
Nope.
Either that or you are saying that unless God is observable and measurable you are not willing to believe God exists.
I'm saying that if God were to exist, there would be two possibilities:
1. God has measurable or observable effects on the world. These effects would be empirical evidence for God's existence. Belief in God could be justified by inference from that evidence.
2. God has no measurable or observable effects on the world. There would be no evidence to use to justify belief in God.
You've told me that case 1 is wrong, so we're in case 2... which leaves no way for belief in God to be justified rationally.
But do you understand that God could be an entity that is neither observable or measurable?
Sure. Positing such a god is called "making **** up."
We can come up with all sorts of claims that can't be proven or disproven by observation or measurement.
For instance, did you know that I'm a magical alien, only masquerading as a human? I do this very well, though - I'm indistinguishable from a regular human by any test you could run on me.
If God is such an entity then we can never observe or measure God. That is what the Bible says God is and Baha'i scriptures confirm that.
You're begging the question again.
Religious scriptures are useless to establish anything about God until you first demonstrate that the scriptures came from God.
Since, at this stage, you haven't even established that God exists, you certainly haven't demonstrated that the scriptures came from God.
I do not know what you meant by "God is irrelevant in every way we can measure." What do you mean by measure?
I mean what you said: "God is unobservable and unmeasurable."
IOW, nothing that would count as a measurement or observation of God can exist.
IOW, God has no observable or measurable effect on the physical universe.
IOW, in any observation or measurement we make, this universe is indistinguishable from a universe where God does not exist.
IOW, God is irrelevant to the physical universe, as far as we can measure or observe.
