The Pharisees and religious leaders confront Jesus, demanding a sign. Jesus offers them only the "sign of Jonah," but what does that mean? Just as Jonah was in the belly of the great fish for three days, so Jesus will be buried in the earth for three days. Furthermore, even the wicked Ninevites repented when confronted by Jonah but these religious leaders will not. How do we respond to the ways that God has been revealed in our lives?
