What is the Messiah supposed to accomplish? The Bible says that he will:
A. Build the Third Temple (Ezekiel 37:26-28).
B. Gather all Jews back to the Land of Israel (Isaiah 43:5-6).
C. Usher in an era of world peace, and end all hatred, oppression, suffering and disease. As it says: "Nation shall not lift up sword against nation, neither shall man learn war anymore." (Isaiah 2:4)
D. Spread universal knowledge of the God of Israel, which will unite humanity as one. As it says: "God will be King over all the world--on that day, God will be One and His Name will be One" (Zechariah 14:9).
