In Luke 21:20-38, Jesus gives some insight into how the temple and Jerusalem (and Israel itself) are no longer the fulcrums through which people are saved. NOW it is through Himself, Jesus. He also tells us about how the End Times will pan out, but instead of giving mere information about it all He spends most of His time telling us how to get ready for it (e.g. Luke 21:28,34,36). Here is my sermon on these things from Luke 21:20-38 (c.f. Genesis 6:9-22).
