Sodom and Gomorrah -Genisis 18

Interesting that when the Lord revisisted Abraham, confirming His promise again, and before Isaac was born, He had a job to do: some serious destroying and killing.
I find the same pattern elsewhere: each time before a significant new generation emerged, there's a massive killing and destroying...
Noah, the flood; Isaac, Sodom and Gomorrah; Moses, lots of baby boys were killed;David, Judges 20(massive killing); Jesus, all the boys under two were killed; Paul, Steven and lots of other persecuted Christians...
So, if in your world you suddenly see lots of unbelievable, abnormal failure and destroy, that might be a sign indicating the new breakthrough is just around the corner.
