Why Is There a Focus on Noah?

There's no preaching to the dead between good Friday and Easter. Instead, there's a reference to the fact that the very spirit that raised Jesus from the dead was the spirit in which he had gone and preached through Noah to the world of Noah's day. Most people were disobedient and they're now in prison awaiting their final judgment. The salvation of such a few people in this huge Roman Empire caused Peter to think of the days of Noah when only eight people came safely through the waters of judgment.
