In Fatima, Portugal, Our Lady of Fatima concluded her apparitions with the Miracle of the Sun. See the last two segments of the 1950s movie. (Click here and here if you can't see the embedded videos).
Our Lady specifically requested, among other things, that Russia be consecrated to her Immaculate Heart. She was very specific, now, wasn't she, in naming Russia? That has not happened. Some try to pass off the consecration of the world by Pope John Paul II as the fulfillment of her request, and point to the collapse of the Iron Curtain as proof. Not so! As rebuttal to their cop-out argument, I need only say one word - Putin!
She asked, from us, frequent Masses, Confessions, Rosaries. We must comply, as the world hangs in balance.
