Jesus told the Pharisees that demanded a sign that the only sign they would get would be the sign of Jonah. Just as Jonah preached repentance, so did Jesus. Unlike the Ninevites, however, the Pharisees did not repent. Also, Jesus stated that just as Jonah was in the great fish 3 days and 3 nights, so would Jesus be in the heart of the earth. Thus predicting His death and resurrection. This message shows us how the story of Jonah predicted Jesus.
