"The Warning" or also called the "New Pentechost" is a supernatural huge miracle that was prophesized by many seers and prophets, some of these are Exorcist Michelle Rodrigue:
the warning was mainly explained by a seer in Garabandal called Conchita Gonzalez, here is a photo of her in an interview:
you can also find the details from the warning in a video called late night show where she is interviewed
and in here she says: "nobody knows when the warning will come"
she also talks about a great miracle that will happen in her hometown, but this, she will just tell when it is going to happen 8 days before it happens
Note: the warning and the great miracle are two different things.
so if somebody tells you a date or when "The Warning" or "The ilumination of conscience" is going to happen, this person is just lying to you
So if you don't see the video, because i know many of you don't even care, the Warning will be a miracle in which you will see your soul, basically like you standing in front of a mirror but watching your soul.
And so that you know, just one bad word (vulgarity, profane word) harms the soul badly and can take up to one whole year to amend.
our Hope is The Sacraments and penance, by following what the Church teaches from 2000 years ago, one can surely save His soul.
