Our Lady of Medjugorje Messages has texts of messages purportedly received from "Blessed Mary" ("Theotókos" in Greek); Medjugorje Videos includes such as Video Apparition for Mirjana, 2. January 2009 (YouTube also has Ten Secrets of Medjugorje from Mirjana Soldo, Q&A with Medjugorje visionary Mirjana, about Jesus and Mary, Medjugorje Visionaries Speak - Jakov & Ivan, and videos of weeping statues at St Mary Statue Crying In Medjugorje, and, near the end of Mirjana in Medjugorje - proof of authenticity).
YouTube has Marian Apparitions in Garabandal, Spain (8 minutes), and Conchita of Garabandal Speaks (22 minutes); Garabandal apparitions (Wikipedia) has a link to Garabandal Videos.
YouTube also has Photo Proof of Miracles (4 minutes), which shows events and interviews concerning both Garabandal and Zeitoun; and Miracles of Medjugorje (4 minutes).
The "Fast Lane to Heaven" button, on the Mission of Angels Foundation home page, has links to messages purportedly received by Ned Dougherty, from beings from the "other side", with the caveat, "The messages are private revelations that Ned believes he has been called upon to reveal to interested readers. As always with private revelations, the reader should use discernment in evaluating the content and the truthfulness of the messages."
Some things seem to heavily involve "matters of the heart" (intuition, etc.), while "knowing" tends to center around one's current time and place (even human memory is notably tricky and faulty). So, why have any respect for words such as the messages linked above, if we can't "prove" whether they are "love and truth", "from God"?
For instance, the February 1, 2009 piece is entitled
"Message from Our Lady of Light" -- Dougherty's book has the claim of his being first made aware of the Zeitoun apparitions partly as a result of an "interior locution":
Apparitions of the "Lady of Light" above Zeitoun Coptic church
1968-70, near Cairo, Egypt
RealPlayer videos, 5 & 8.5 minutes
These messages, and Dougherty's book (which, in March 2001, roughly predicted the 9/11 attacks) have a heavy portent for the future -- they seem to coincide strongly with what Howard Storm said he was shown, about humanity's future (http://davecoop.net) -- and, they strongly indicate a huge "paradigm change" coming, for humanity.
