WW3 has already begun politically, economically, and technologically at least. And, really, we are already engaged in the actual battle in Ukraine against Russia and the Middle East against Iran and their proxies; we just don't have "our boots on the ground" yet, at least not officially. The next step I do not want to see is all out war with Russia, China, Iran, and North Korea. That could be end of the age Jesus referred to:
Matthew 24:21-22
New King James Version
21 For then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be.
22 And unless those days were shortened, no flesh would be saved; but for the [
a]elect’s sake those days will be shortened.
