No, we are not liars. You are the one that keeps saying that we said we were "certain," but you have produced no proof to that effect.
To quote this again, is there any uncertainty expressed here?
What does the Bible show as to the meaning of all these world events? It shows that for this unrighteous world time is running out fast! It shows that within a few years at most there will take place a climax in human affairs so gigantic that it will affect every person earth, every man, woman and child....Time is running out fast for it! It is much later for this world than you may think! Indeed, it has only a few more years of existence left!...The events that Jesus, the apostle Paul and other Bible writers bring to our attention were all to take place within the same generation (Matt. 24:34). These events would identify which generation's lifetime would embrace the "last days", much as your fingerprint identifies you...The fact that fifty-four years of the period called the "last days" have already gone by is highly significant. It means that only a few years, at most, remain before the corrupt system of things dominating the earth is destroyed by God. How can we be so certain of this?....
Jesus was obviously speaking about those who were old enough to witness with understanding what took place when the "last days" began. Jesus was saying that some of those persons who were alive at the appearance of the 'sign of the last days' would still be alive when God brought this sytem to its end. Even if we presume that youngsters 15 years of age would be perceptive enough to realize the import of what happened in 1914, it would still make the youngest of "this generation" nearly 70 years old today. So the great majority of the generation to which Jesus was referring has already passed away in death. The remaining ones are approaching old age. And remember, Jesus said that the end of this wicked world would come before that generation passed away in death. This, of itself, tells us that the years left before the foretold end comes cannot be many....
Still some persons may say: "How can you be sure? Maybe it is later than many people think. But maybe it is not as late as some persons claim. People have been mistaken about these prophecies before." True, there have been those in times past who predicted an "end to the world," even announcing a specific date. Some have gathered groups of people with them and fled to the hills or withdrawn into their houses waiting for the end. Yet, nothing happened. The "end" did not come. They were guilty of false prophesying. Why? What was missing? Missing was the full measure of evidence required in fulfillment of Bible prophecy. Missing from such people were God's truths and the evidence that he was guiding and using them.
But what about today? Today we have the evidence required, all of it. And it is overwhelming! All the many, many parts of the great sign of the "last days" are here, together with verifying Bible chronology....Would you still doubt if someone told you that winter was coming very soon? Would you say that he was just guessing or merely expressing his own idea? Or would you acknowledge, on the basis of solid evidence, that he knew the facts and was telling you the truth? ...We today have all the many parts of that sign, nearly forty of them, being fulfilled within the same generation, and we have God's timetable, his "calendar," showing that the time has nearly run out for the present unrighteous system of things. This is very different indeed from the situation with those who proclaimed an "end to the world" in earlier generations. (Awake!, 10/8/1968, pp. 4, 7, 13-14, 23-24)
