The deity is not incapable but it is unwilling to prove to humans that it exists because it wants humans to prove to themselves that it exists by looking at the evidence.
I think it's because there either is no deity, or, if one exists, it is unaware of us, indifferent to us, or unable to communicate effectively. You say that the deity wants us to be convinced by evidence that isn't convincing. But even if you were correct, it remains logically unsound to believe that such a deity exists absent sufficient evidence. You describe a deity that doesn't want to be known by people who have strict, empiric criteria for belief. If that deity exists, it failed to make itself known to those that aren't convinced by messages from people claiming to represent gods. Either way, there is nothing there for people like me, so we walk away.
Obviously Messengers will be ineffective for human beings that require more, but God is not going to accommodate every single person in the world and make sure they all become believers.
There is no reason to believe that, but even if we stipulate to it, it simply means that such a deity is uninterested in people not convinced by messengers, as it should be clear to a deity what such people require and refuses to provide it. Fine. And off we go on our merry way living life as if there is no deity.
Messengers are a method for a God who wants to be believed on faith
That leaves critical thinkers out.
there is evidence that indicates that the Messengers are more than mere men.
No, there isn't. If you have such evidence, why haven't you presented any? Everything you've cited from messengers, which you usually change to blue, is words that any number of people could have written. I could write like that. If I wanted to start a new religion, I could write a lot of flowery words about peace, love, what God wants, what God has done, and the like. I've grabbed a bunch of Baha'u'llah quotes as examples:
- Ye are the fruits of one tree and the leaves of one branch.
- O king! I was but a man like others, asleep upon my couch, when lo, the breezes of the All-Glorious were wafted over me, and taught me the knowledge of all that hath been. This thing is not from me, but from One Who is Almighty and All-Knowing.
- Through affliction hath His light shone and His praise been bright unceasingly: this hath been His method through past ages and bygone times.
- We desire the good of the world and the happiness of the nations that the bonds of affection and unity between the sons of men should be strengthened... what harm is there in this?... these fruitless strifes, these ruinous wars shall pass away, and the 'Most Great Peace' shall come.
Is that what you mean by evidence of God? If so, you underestimate humanity. How many thousands or millions of people could have written that? I guess you must believe that you couldn't have written them to consider such words evidence of the Almighty, but that's not how I feel. I could write in vague, exhortative, laudatory language
O Almighty! Ye are the Sons and Daughters of a glorious God, who hath made a place for you, and who singeth a lilting song of unity and peace that is like honey unto the ear, a song of love and bonding, a glowing beacon of the Tabernacle that sustaineth like mother's milk and the fruit of the tree.
Silence the tongue and lift ye unto Him, for there are no greater riches than communing with the All-Knowing.
I could throw in phrases like forked-tongued viper, throughout the ages, worship, betterment, brothers, the light of the sun, the moon guarding the night, the endless sea of stars, beyond understanding, etc.. How much of this would I have to write to convince a few hundred thousand people that I was a messenger of God?
Apologies if this seems like mockery. That's not my purpose. I am merely rebutting your claim that such language is evidence of divinity.
You cannot say the best method was not used unless you know of another method that would be better, and you cannot know that another method would be better since no other method has ever been used.
That is incorrect. You don't know what is knowable to others. You only know what is knowable to you given your ways of knowing.
Of course other methods of communicating have been used, just not by any deity. I've used other methods, and so have you. We are now.
And that is the jist of the argument. Whatever cannot equal man cannot be called a deity.
I've been mentoring a budding bridge player who is a quick learner with a good, analytical mind. He considers it like magic when I point out to him that East must have had the queen of diamonds or declarer must have a spade void, and explain how I knew. He tells me that it is his goal to arrive at the place where he can use inference to appear to do magic at the table. He knows what he doesn't know, and he knows that others can know more than he does, and can be certain where he can't.
I don't think you are aware that there are ways of thinking that can generate knowledge that you don't know about. It comes out whenever you write that something is only opinion when others can know it for fact. We see it all the time, as when anti-vaxxers assert themselves and contradict the scientists, people who think any opinion is as good as any other because they're all just created out of thin air.
That faith is a deviation from reason is just your personal opinion.
Here's a fine example.
No, that is a fact, whether you agree or not, assuming that we are talking about religious-type faith, or unjustified belief, and not trust based on prior experience, as in faith that the car will start based on the last several hundred successful tests of it starting. That's a different word - a homonym - with a different definition (justified belief, or belief derived from the application of valid reasoning to evidence).
In fact, you ought to be able to see that faith and reason are mutually exclusive ways of knowing by recognizing that one produces justified belief and the other unjustified belief.
I know how much you dislike reading such words, and you see them as arrogant. Sorry if that's still the case, but you can't expect me to concede that what I know as fact is nothing more than ungrounded opinion because you don't follow the argument.
