How do we know that Messiah has come?

A lot of scholars and even believers out there are quick to undermine the ministry and even the existence of Yeshua/Jesus Christ. However, the entire world serves as a witness that something amazing happened when He rose from the dead – the world changed drastically and has never been the same. Not only can we prove that He was a real person, but we can also prove that He destroyed the sting of death by looking at the world before and after His death, burial, and resurrection.
