While there is no "last straw" concept identified in scripture, I would agree that we are experiencing labor pains....
1) Number of large earthquakes in the world below average for 5 years running...
2) No volcanic eruptions above VEI=5 for 14 years...
2)World most peaceful (fewest wars) currently than it has been in decades.
Yep, that Rapture is imminent.
I'm unaware of any scriptures relating to those three items in the way you speak of them. Jesus did not tell us that the
number of earthquakes would increase. He never spoke of volcanic activity. He also never spoke of
increased war activity.
Scripture does, however, speak of last days scoffers.....
