I found this video very interesting. We certainly live in difficult and challenging times. How would things be different if one of the popes had listened to Mary's request and consecrated Russia in the way she asked? There have been several imperfect consecrations which brought limited good results, but Mary's request remains unfulfilled after a century.
Remember what happened in France after King Louis XIV failed to honor God's command to consecrate France to the Sacred Heart of Jesus. One hundred years later to the day, his great, great, great grandson, King Louis XVI, was stripped of his crown and imprisoned. Several years later he was sent to the guillotine. While he was in prison he placed a promise within the walls of his cell to consecrate France if he were release. He was, indeed, released by death several in 1793. The document was discovered in the wall about 80 years later when the Tuileries, used as his prison, was demolished.
Makes you think about the disasters we are experiencing in the world and the Church, doesn't it?
