What do you have to determine that these "Messengers" were indeed informed by or sent on a mission by God? What do you have? I would argue that you have only words yet again. And even worse here, you have only the words of one specific individual and whoever else he has convinced that his/her words are true. That's literally all you can possibly have. Unless you want to cite "feelings" you get that you suspect are also "from God" and which you might interpret are God trying to "tell you" that this Messenger is telling the truth. But even then, the only evidence you have to share with others are the words that you just admitted are a poor form of evidence.
No, I do not only have words. That would be insufficient because many men have written words and made claims they were sent by God, and they were not so that is not proof of anything.
I have the
Person of the Messenger and
the mission that He accomplished, and these are the most important evidence that indicates the Messenger was from God and communicated to by God. Mind you, there can never be any proof that God sent or spoke to a Messenger, since there can never be any universally accepted proof that God exists. All we can ever hope to have is evidence, and for some of us that evidence is proof.
The Person of the Messenger is His character as evidenced by who He was, what He did in His life. In the case of Baha'u'llah that includes the scriptures that He wrote, which was part of His mission.
The Messengers of God were also Manifestations of God and all of them were evidence that God exists.
God is everlastingly hidden from our eyes and can never be seen so all we have are the Messengers who are the Voice of God on earth.
“He Who is everlastingly hidden from the eyes of men can never be known except through His Manifestation, and His Manifestation can adduce no greater proof of the truth of His Mission than the proof of His own Person.” Gleanings From the Writings of Bahá’u’lláh, p. 49
All of the Manifestations of God were evidence of God. How do we know that they were true Prophets and not false Prophets?
Matthew 7
15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
20 Wherefore by their fruits ye shall know them.
Fruits: the pleasant or successful result of work or actions:
fruit
"Bahá’u’lláh asked no one to accept His statements and His tokens blindly. On the contrary, He put in the very forefront of His teachings emphatic warnings against blind acceptance of authority, and urged all to open their eyes and ears, and use their own judgement, independently and fearlessly, in order to ascertain the truth. He enjoined the fullest investigation and never concealed Himself, offering, as the supreme proofs of His Prophethood, His words and works and their effects in transforming the lives and characters of men......
In the chapters that follow, we shall endeavor to show whether Bahá’u’lláh’s claim to Prophethood stands or falls by application of these tests: whether the things that He had spoken have followed and come to pass, and whether His fruits have been good or evil; in other words, whether His prophecies are being fulfilled and His ordinances established, and whether His lifework has contributed to the education and upliftment of humanity and the betterment of morals, or the contrary."

And then you seemed so shocked that atheists inform you that these "Messengers" you want to point to are not evidence. Again... it is hearsay, and there is no way to tie their proclamations about the knowledge they hold directly to God. Even if you want to point to some scripture and say that the coming of a particular "Messenger" was heralded in the text as a form of prophecy... this is again, just words that you want to try and use to back up more words. It isn't enough for me. And I am strongly of the opinion that it shouldn't be enough for anyone.
I am hardly shocked as I have been posting to atheists 24/7 for about nine years on various forums and they all say essentially the same things about Messengers of God.
No, there is no way to
prove that the proclamations of the Messengers about the knowledge they hold came directly from God, and that is where faith comes into play, as what cannot be proven has to be believed on faith. However, it would be foolish to believe on faith alone, if there was no evidence to back up their claims.
