Messianism is the belief in a Messiah, a savior or liberator who is expected to bring about a transformative change in the world. This concept is prominent in several religions, including Judaism, Christianity, and Islam, each having its own interpretation of the Messiah's role and significance. In Judaism, the Messiah is anticipated to restore Israel and bring peace, while in Christianity, Jesus is viewed as the Messiah who offers salvation. Islam also recognizes Jesus as a significant figure, believing he will return to fulfill his role in the end times.
