Your observations are correct, TheBlackCloud.  Evil messengers of Satan are bringing disrepute upon the True Faith, with all of their false predictions.
The countdown (within that generation) won't begin until the ten lost tribes of Israel (the Northern tribes) are returned to the land of Israel.  Right now mostly only the Southern tribe, Judah (which is why all modern Israelites are called "Jews"), part of Benjamin, and Some of Levi are occupying the land of Israel.  The Bible even says that just prior to the last days, many will say that the supposed time has come and gone, and Jesus still hasn't returned.
1800 years ago, the Christian faith was changed from a dynamic relationship with God, and turned into a superstitious religion.  The ones referred to as the "Unchurched" may possibly be where the majority of the few real Christians can be found right now.
I believe that most of them are in countries where they are being heavily persecuted, even being put to death for their faith.
