Is there a man called Messiah who was promised by God? Did he come? Or will he come? Isaiah gave the most straightforward prophecy — Isaiah 7:10-25 — about him. Since then, a lot of efforts have been made to figure out "Who is he?" However, to acknowledge Jesus as the only fulfillment of the messianic expectation, a possibly correct interpretation is not enough. One also needs a leap of faith.
