With the fall of the Towers, God, the creator of the world, shows to mankind the value of his word, , that fulfills, and it’s perfect to the minimum details, as is the world he created, as he says throughout his son: Lc. 21:
33- Heaven and earth shall pass away: but my words shall not pass away.
1º Pe: 1. 24 -For all flesh [is] as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away:
25- But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.
This prophecy, is the big revelation of God, for the last time, and the largest of them all, because God in his love, showed us this one before the other ones were fulfilled (shows us the end of this world), giving time for everybody to read the bible, and believe more in it, so each one can prepare and purify, himself and his church for the 2nd arrival of Christ that will soon come to find his church.

This prophecy shuts the mouth of unbelievers and atheists, who said that previous prophecies were written after the fact had occurred, and still doubt some facts.
This vision is clear, and its founded, because comes from God, not like devil’s, prevision with Nostradamus and (not) our lady of Fatima, (but theirs) that are obscure and confuse.
God simulated a conversation with his people, about future prophecies, so they can be alert of what is about to happen, and talks in the past in: Isaiah 41. 21 a 29
21- Produce your cause, saith the LORD; bring forth your strong [reasons], saith the King of Jacob. (They complaint to God)
22- Let them bring [them] forth, and shew us what shall happen: let them shew the former things, what they [be], that we may consider them, and know the latter end of them; or declare us things for to come.
