Well thank you for quoting a scripture that we can look at.
Matthew 24:34 Verily I say unto you, This generation shall not pass, till all these things be fulfilled.
So before being told that we don't know the day or hour he tells us that this generation (referring to the fig tree generation when Israel shot forth the new leaves again after the winter was over).
35 Heaven and earth shall pass away, but my words shall not pass away.
Yes, the prophecy that Israel would be reformed is one of the greatest prophecies in the Bible along with Ezekiels vision of the dry bones living again. There are pictures of the people in the death camps after WWII looking like skeletons walking out of their graves. These prophecies being fulfilled should be a powerful confirmation to us that the Lord's words will not pass away and that they will all be fulfilled.
36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
This verse is a powerful word that tells us there is no prophecy in the Bible or in other books like the book of Enoch that tell us the day and the hour. The Fig tree generation prophecy tells us the generation. So we have two sides of the coin. There are prophecies that will tell us that the Lord's coming is at hand, and that it is very near, but there will not be any prophecy that tells you at 2am on Nov 14th the Lord returns. That is the kind of hoax that the cults have used.
37 But as the days of Noah were, so shall also the coming of the Son of man be.
Wow, do you see that your verse about not knowing the day or hour is stuck between a prophecy that tells us the generation and a prophecy that likens it to the days of Noah! Didn't Noah know what week the flood was going to hit? The world mocked him, ridiculed him, ignored his warnings and they were caught by surprise. But Noah and his family weren't.
38 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark, 39 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
So how do we reconcile this? I already gave you several verses in Post #24 that tells you that God doesn't do anything without telling his prophets. He told Ezekiel and Daniel and other prophets like Joel key pieces to the puzzle that let us know the day is approaching, but He didn't tell any of them the day or hour. That doesn't mean He won't tell prophets in the future the day and hour. Otherwise how is it like the days of Noah and what is the point of the warning to the church in Sardis and how is Amos true when he says God does nothing without telling the prophets?
