The prophets taught that God would send a person to the world who would help all the people of the world see that God is the maker, king of the world and has supreme power. This person is called the Messiah. The word Messiah comes from the Hebrew word "mashiah", which means "the anointed one". The Book of Isaiah says the Messiah will be a just king who will unite the Jewish people and lead them in God's way. The Messiah will also unite all the people of the world to serve God. People will act with justice and kindness, and the whole world will be filled with peace.
