This second hour comes from the Father’s wisdom. He foresaw Satan’s actions and planned his defeat. The first hour took place on Calvary when the Father used His Son Jesus. the second hour will take place in Jerusalem and the Father will use a special son of Mary again.
In a single moment, all the world will see and will be shocked. These scenes will go forth and will carry the grace of true repentance. Mary will be the preacher, reminding everyone of her Fatima prophecy. The second hour will be another martyrdom, this time witnessed by the whole world.
