Mary will reveal all the great events at the proper time. She must find people who believe and prepare them, even by great trials. She needs these believers because the Medjugorje events are very close.
There will be a series of events, some from hell and others from heaven. There will be external events and interior experiences as heaven and hell contend for humanity, a conflict not seen since Jesus died on the cross. The whole future of earth will be at stake.
