The Medjugorje visionaries say the secrets will be realized during their life times. Another hint at the timing of the secrets is when Vicka, in 2001, told Father Livio Fanganza that she believes he will be alive during the time of the great sign, the third secret. In 2001, he was 60-61 years old when she told him this. He is currently 85 years.
Another hint: Father Petar who supposedly has been chosen to disclose the secrets is now 79 years old (born October 1946).
I've thought for awhile that the 2033 date marking about 2000 years since the end of Jesus' earthly life would prove to be significant.
Yes the age of the visionaries gives us a rough idea that it will be soon enough. Another indicator is that the Great Sign and Miracle will occur when things are at their worst. I don't think there is any doubt that we are on the immediate run down to things. For instance we know that with the Iran War things are going to grow very much worse. I got a message from an expert in Garabandal saying he thought it would be a few years yet. If I had to make a guess myself it will be within the next two or three years at the outside. But it's only a guess. They don't call them secrets for nothing. But they say when they do start events will move very quickly.
I notice that Medugorje is under a lot of public attack again at the moment. Perhaps that is another sign in itself.
