We do have a crystal ball, Baha'u'llah. Baha'is believe Jesus is the true Messiah to the Jews. Because of those "prophecies" in Matthew, just on those, I can see why the Jews would reject Christianity. The verses are taken out of context and the events might not have even happened.
I'll go even further, why use the name Jesus? Why not his Hebrew name? Which was, I guess, Yehoshua. His last name would be Bar Yosef? Whether you or I believe Jesus rose again physically and is coming back physically isn't the problem. Christians believe those things are true.
They wrote the gospels and epistles. They interpreted them. We can call them crazy. We can say they made things up and added them into the story. We can say that maybe they were meant to be symbolic. But, that's us. We don't believe the NT literal... or at all. We can say the modern liberal Christians don't believe those things were literal, but the early Christians did. Would I trust what people 2000 years ago said about the person they say was the Son of God? If they say he walked on water and rose from the dead, who would believe such a thing? A lot of Christians, that's who. We're telling them that they are wrong. And they are telling us we are doomed and going to hell. They NT says the "Lamb" is coming back. The name Jesus is mentioned a couple of times as returning, but does any of it make sense? No, it is not easy to figure out.
They have Jesus in their hearts. They can feel the power of the Holy Spirit. They can count on the whole Bible as being the inerrant Word of God. You have what you believe to be the truth about God in your heart. But you both believe totally different things about God. So, for me, what is the truth? People can believe many different things. Those things can contradict what other people believe. But, for those that believe, they can feel it. It changes their lives. But one or both of them are really true. But, they are believed as true. So what's real? Your beliefs are real to you. And you have Bible verses that "prove" you are right. Their beliefs are real to them, and they have verses that prove it to them. So what you gonna do? Each has to prove the other wrong.
Or, like you've probably have found with liberal Christians, they don't care about taking the Bible literal. Well then, that solves the problem. Should anybody in any religion take their beliefs so serious? Even Baha'is? You've been about the best at listening to the beliefs and opinions of people in the other religions. But, too many Baha'is sure seem to be pushing people away by being to stuck on their beliefs... that the Baha'i Faith is the truth, and therefore the people in the other religions are wrong. That ain't working.
I see your argument confirms the principal of progressive revelation.
It is easy to say in this age, that people of an age 2000 years ago, or even 300 years ago had any concept at all, as to what it was to think and act globally.
The issue is not being flexible in understanding a message aimed at our spiritual growth. Spiritual growth is required to find the balance in this material creation.
