"An adulterous generation seeks for a sign"

Scripture: Matthew 12:38-42

Jesus gave a rather stern warning to his generation when they demanded a sign from him. It was characteristic of the Jews that they demanded "signs" from God's messengers to authenticate their claims. Jesus faulted them for one thing: spiritual adultery. The image of adultery was often used in the scriptures for describing apostasy or infidelity towards God. 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.
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.
