Q: Why do none of the NT books recall the events of 70AD?

The destruction of Jerusalem and the temple must have resounded like an earthquake round the Christian churches in 70AD. Even a cursory reading of the NT makes it clear that the status of the Jews and the Jewish religion were huge issues for the NT church. yet, as far as I know, the only possible references to the events of 70AD see it as a future event.

I can only think of three possible answers to this question:

1. Almost all the NT books were written pre-70AD - contrary to what most scholars of all stripes and all ages believe (as far as I am aware from my limited knowledge).
2. It wasn't as big a deal as everyone thinks it was. The NT Christians knew that the temple of Jesus' body had already been torn down and rebuilt. The physical temple was yesterday's news and nobody cared.
3. There are references to the destruction of Jerusalem all through the NT, but I am just too blind and ignorant to see them.

As God is continually reminding me - you can't understand his Word without his Spirit, so I will be praying about these nagging questions I'm putting down. But as I said before, this is partly an appeal for help from those who have more of the Spirit than I do.

Q: Should the Israelites have rejected the Mosiac Law?

A: Errm...well obviously the answer to my nagging question should be 'no'. But when you hear many people talk about 'the law' you can't help feeling that the answer should be 'yes'.

When Moses came down mount Sinai perhaps the Israelites should have responded "You know what Moses, God already has an unconditional covenant with us as children of Abraham. We know that we are accepted on that basis, without circumcision, by faith alone. Frankly Moses, you are selling us down the river with a works-based righteousness that will not lead to life. We'll stick with the unconditional covenant of Abraham and reject your man-made legalism."

You know your understanding of the Mosaic law is wrong when you cannot pin down why that should not have been the Israelites response to the giving of the law.

... I am pretty sure my understanding of the law is wrong!

"But the law is not of faith..."

By the way, this is going to be the start of a mini-series of nagging questions (not doubts) about the Bible. I don't know the answers to any of them so please feel free to help me out.
