"I'm convinced that the Lord is coming for His Church before the end of 1981." (Chuck Smith, Future Survival)And Hal Lindsey
"Since a generation of judgment is forty years and the Tribulation period lasts seven years, I believe the Lord could come back for His Church any time before the Tribulation starts, which would mean any time before 1981. (1948 + 40 - 7 = 1981)." (Hal Lindsey, The Late Great Planet Earth)
OHH I must add them to my list of failed end time prophecies!
