I found a web site called Please Convince Me and there I read an article about dating the New Testament. The part that intrigued me most was this:
"Perhaps the most significant event of the first century, particularly in the minds of Jews and early Christian converts, was the destruction of the Jewish temple in 70AD. Rome dispatched an army to Jerusalem in response to the Jewish rebellion of 66AD. The Roman army (under the leadership of Titus) ultimately destroyed the temple in 70AD, just as Jesus had predicted in the Gospels. Yet no gospel account records the destruction of the temple. In fact, no New Testament document mentions or alludes to the temple’s destruction, even though there are many occasions when a description of the temple destruction might have assisted in establishing a theological or historical verification. The most reasonable explanation for silence related to the destruction of the temple is simply that all the New Testament documents, including the gospels, were written prior to 70AD."
