If that is your issue, reread my post. I was saying naming a date and time is NOT a good idea.
As to the signs of the times, one word. Israel. I know you reject this. I can’t help that. But, Israel is why I believe that He truly is coming soon. Is it within the next 100 years? I believe so, but could be wrong. It would not surprise me to hear the trumpet sound this afternoon.
If you can't pick a date, then why the 100 year comment? Sounds like a form of loose date-setting to me. Is this one of those "Jesus said we couldn't know the day or hour but that doesn’t mean we can't know the century" excuses?
As far as modern, secular Israel is concerned, it bears absolutely no resemblance to Israel of the Bible. Why you would hang your hat on this "sign" beyond understanding. Perhaps it’s all you have been told for the last few decades from the pop prophecy preachers like Chuck Smith. That must make it true.
