Similar but does not have to be the Christian God. Your messiah could be Buddha.
yes

Yes God is the one and only Messiah
Only Allah (or God in English and same God worshiped in Judaism Christianity and Islam) knows when the messiah will come back to earth and when the moon will revert back to its original size
In other religions, I don't know what their beliefs state. In Judaism, the answer is no. The messiah whom we await is to be fully human. See more on this topic towards the bottom of this linked page.
Jesus "The Messiah" is God in human form. He came to save the world from our sins, which separated us from God.
messiah
Christians believe that the Messiah was sent by God to save humanity.
George Fredrick Handel He wrote the song Messiah
Jews call "the Messiah" as "the Messiah" or in Hebrew "HaMoshiach" (המשיח). However, as opposed to other religions, such as Christianity or Islam, Judaism does not believe that the Messiah has come yet and therefore is not identified with any person. For example, Jews don't believe that Jesus was the Messiah and, therefore, do not accept the Christian or Islamic claims that he was a God prophet or God/son of God.
In the Bible it says that that Jesus is God. He is three in one. Father, Son, Holy Spirit. So, yes he is the Messiah and Jesus is God!
