Baha’u’llah could have been mistaken but sincere. That is a possibility. You get to choose whether to believe that was the case because you have free will to choose. I choose that He heard from God because it is obvious to me that was the case. In my logical mind, I cannot believe that any man could make so much stuff up about God or why He would do so. It makes no sense at all so I could never believe it.
Moreover, what He wrote about God is essentially what the Bible and the Qur’an say, with a few additions and embellishments, so that would mean the other scriptures were also mistaken. You are free to believe that if you want to, but count me out. It makes no logical sense to me that 55% of the world population who are Christians and Muslims and believe in God are mistaken about God.
I can say the same thing about you: But your method of evaluating evidence is flawed. Just because you looked at evidence and hold an opinion of what it signifies does not mean you are correct.
My two statements above do not contradict themselves in any way. The evidence that supports Baha’u’llah’s claims has NOTHING to do with the fact that there is no objective evidence for God.
There is evidence for God, you just don’t like the evidence.
I know what you are getting at and I have covered this before. Since there is evidence but no proof that God exists, there are three logical possibilities:
1. God exists and sends Messengers as evidence (theist)
2. God exists and does not communicate with humans at all (deist)
3. God does not exist (atheist)
No, I do not see it as evidence against such a God. Below I will explain why.
God does want to be known, and the evidence that God provides, Messengers, are how we can know God.
Since God doesn't
prove that He exists, but rather provides
evidence that He exists, then all doubts about God's existence are on the people who reject the evidence that God provided.
The reason that God does not
prove He exists is noted below.
“He Who is the Day Spring of Truth is, no doubt, fully capable of rescuing from such remoteness wayward souls and of causing them to draw nigh unto His court and attain His Presence. “If God had pleased He had surely made all men one people.” His purpose, however, is to enable the pure in spirit and the detached in heart to ascend, by virtue of their own innate powers, unto the shores of the Most Great Ocean, that thereby they who seek the Beauty of the All-Glorious may be distinguished and separated from the wayward and perverse. Thus hath it been ordained by the all-glorious and resplendent Pen…”
Gleanings From the Writings of Bahá’u’lláh, p. 71
In the context of the passage above,
If God had pleased He had surely made all men one people means that God could have made all people believers, but
if God has pleased implies that God did not please to make all people into believers, which is why all men are not believers.
The passage goes on to say
why God didn’t please to make all men believers... In short, God wants ll men to make a sincere effort and become believers by their own efforts (by virtue of their own innate powers). God wants to separate those people from the others who are unwilling to put forth any effort.
If God
proved to everyone that He exists then nobody would have to put forth any effort and it would be impossible to know how much effort people are willing to put forth, thus demonstrating how much they really care about believing in Him.
