That's right. And a day will come when earthquakes will have immediate eschatological significance; but the overall scene at that point will be, in my understanding of Biblical prophecy, pretty unambiguous.
So I picture myself in dialogue with someone from this country:
Q -- Is this earthquake a direct judgment of God for my people's sin?
A -- I don't know. But God is sovereign, and in His hand is your own life-breath, as well as that of your nation... as well as my own.
Q -- Should we should I repent of our sin and put our faith in Jesus as Lord, Savior, and God?
A -- Yes.
Yep...It's like when Jesus was talking about the men killed at the altar by Pilate and the people killed by the falling tower...not that they were great sinners, but that we always need to know that life is impermanent, and therefore, we need to be ready. Who knows when the Bridegroom is coming?
