Hi Desi
I hope this is not the only reason you left as it isn't a valid one to judge them on. All Prophecies are subjective. We are given prophecy to try and undertsand, in this case Jesus says "generation" and we have to try to decern it. Moses was "inspired" and so had that added accuracy. The Anointed in this time do not have the gift of "inspiration" when we look at Bible prophecies we are to decern their meanings so as to be "ready" and "on watch" God does not expect a level of accuracy from us that you and others on here seem too.
Did noah know when the rainwaters would come he only knew they would be soon in fact the Bible mentiones 120 years but not that God said this to noah.
Genesis 6:3
3 Then Jehovah said, "My Spirit will not contend with [a] man forever, for he is mortal [b] ; his days will be a hundred and twenty years."
it was after he said this that he saw 500 year old noah.
Genesis 5:32 (New International Version)
32 After Noah was 500 years old, he became the father of Shem, Ham and Japheth.
Genesis 6:8
8 But Noah found favor in the eyes of Jehovah
and yet Noah himself was 600 when the flood actually happenned clearly waiting many, many years but building the ark getting ready for when it did finally happen.
Genesis 7:6
6 Noah was six hundred years old when the floodwaters came on the earth.
again the christians didn't know when jerusalem would be destroyed.
Prophecies were deliberately designed to be obscure and need reference to the WHOLE Bible to be understood with any kind of accuracy. Hense why it is predicted we will need "refinement" until the end.
Daniel 11:35
Some of the wise will stumble, so that they may be refined, purified and made spotless until the time of the end, for it will still come at the appointed time.
Jesus himself had to explain which prophecies he fulfilled.
Luke 24:27
And beginning with Moses and all the Prophets, he explained to them what was said in all the Scriptures concerning himself.
showing it had not already been seen. Prophecy is only 100% in hindsight.
Here is the choice laid before the anointed or indeed any group that claim to be christians....
Should we try to decern prophecy knowing we will not be know the full truth untill after it is fulfilled?
should we ignore it for these same reasons?
should we bury it unused as the majority of christendom has?
should we let all our flock have differing opinions (allow divisions) and not guide them to agreement?
1 Corinthians 1:10
[ Divisions in the Church ] I appeal to you, brothers, in the name of our Lord Jesus Christ, that all of you agree with one another so that there may be no divisions among you and that you may be perfectly united in mind and thought.
The answer to all these is why I have no problem with going with any current understanding of Bible prophecy. Prophecy is a unique part of the bible and easy to point accusing fingers at. But note all these nay-sayers to the current "generation" understanding offer no alternative explanation for this prophecy.
