He said, "Well, you know, the Bible does say that things will get better right before the tribulation."
It always amazed me (even as a more or less believing JW) how people could say things like this and not realize that it's just hedging against any eventuality. Whatever happens, they'll say Ha! the bible predicted this! the end must be so close! This hedging was actually one of my principle doubts early on.
In any event, the bible says nothing about the gradual improvement we're seeing. It says there will be a widespread cry of peace and security and then the end will be INSTANTLY upon them. I guess that wouldn't make a difference, though...if "soon" encompasses the last 130 years, then "instantly" could well last long enough that everyone forgets the cry of peace and security anyway.
Even without that, though, this sort of long-term trend completely disproves the WTs basic premise - that mankind cannot solve their problems or make anything better and we NEED god's intervention. Meanwhile, humans have been solving their problems left and right for centuries. I just can't wait until 1 Corinthians 15:26 sees fulfillment: " And the last enemy, [religion], is to be brought to nothing." (sorry, my desire for intellectual honesty won't let me remove the brackets on the changed word)
