Was Jesus really a Messiah?
The Jews said that the true Messiah would usher in an era of peace and tranquility peace and a brotherhood among men. He would restore Jerusalem etc.
Did Jesus do any of that? I think not. After Jesus left the world became much more violent and dangerous. Hatred became the norm. Wars, famines, atrocities one after the other over the centuries and who knows what other horrors are in store for humanity.
If you actually believe Jesus is the Messiah explain why. None of what he was supposed to do came true.
