Talking about 1975 and the push by the society got me to looking at some older quotes. This one here really bugged me and still pisses me off when I read it.
In this instance they are telling you to forget about Jesus and listen to the society.

"One thing is absolutely certain, Bible chronology reinforced with fulfilled Bible prophecy shows that six thousand years of man's existance will soon be up, yes, within this generation! (Matt.24:34) This is, no time to be indifferent and complacent. This is not the time to be toying with the words of Jesus that "concerning that day and hour nobody knows, neither the angels of the heavens nor the son, but only the father." (Matt 24:36) To the contrary, it is a time when one should be keenly aware that the end of this system of things is rapidly coming to its violent end. Make no mistake, it is sufficient that the Father himself knows both the "day and hour"!
