What sign alone did Jesus say would be given to the evil and adulterous generation?
Jesus said no sign would be given to that evil and adulterous generation except the sign of the prophet Jonah. As Jonah was three days and three nights in the whale's belly, so the Son of Man would be three days and three nights in the heart of the earth.
When the scribes and Pharisees asked for a sign from Him, Jesus answered that an evil and adulterous generation seeks after a sign, and no sign would be given to it except the sign of the prophet Jonah. He explained that just as Jonah was three days and three nights in the whale's belly, so the Son of Man would be three days and three nights in the heart of the earth. Les connects this to the gospel: Christ died, was in the grave three days and three nights, and rose from the dead. Putting faith in that gospel separates the believer from the old life of sin and bondage.
Then certain of the scribes and of the Pharisees answered, saying, Master, we would see a sign from thee.
