We look at the whole subject of signs and why they were given.
At first sight, Jesus’ response to the Pharisees’ request may seem harsh. We need to remember, though, that they had already seen many signs to authenticate who Jesus is.
Jesus shows that signs were not for unbelievers, but were given in order to strengthen the faith of believers. The sign Christ promised the Pharisees was the sign of Jonah, pointing to His death, burial and resurrection. It was a sign of judgment, showing them that the message would be taken from them and given to the Gentiles.
