Many fatalities could be avoided if people took the warning signs seriously. When the religious leaders demanded a sign from Jesus, he gave them a warning to avert spiritual disaster. It was characteristic of the Jews that they demanded "signs" from God's messengers to authenticate their claims. When the religious leaders pressed Jesus to give proof for his claims he says in so many words that he is God's sign and that they need no further evidence from heaven than his own person. The Ninevites recognized God's warning when Jonah spoke to them, and they repented. And the Queen of Sheba recognized God's wisdom in Solomon. Jonah was God's sign and his message was the message of God for the people of Nineveh. Unfortunately the religious leaders were not content to accept the signs right before their eyes. They had rejected the message of John the Baptist and now they reject Jesus as God's Anointed One (Messiah) and they fail to heed his message. Simeon had prophesied at Jesus' birth that he was "destined for the falling and rising of many in Israel, and to be a sign that will be opposed so that inner thoughts of many will be revealed" (Luke 2:34- 35). Jesus confirmed his message with many miracles in preparation for the greatest sign of all – his resurrection on the third day.
