All true:
“One day the King fell seriously ill and when he was given up for dead he found himself, in a vision, before the judgement seat of Our Lord. Many devils were there accusing him of all the sins he had committed and Our Lord as Sovereign Judge was just about to condemn him to hell when Our Lady appeared to intercede for him. She called for a pair of scales and had his sins placed in one of the balances whereas she put the rosary that he had always worn on the other scale, together with all the Rosaries that had been said because of his example. It was found that the Rosaries weighed more than his sins.
Looking at him with great kindness Our Lady said: “As a reward for this little honor that you paid me in wearing my Rosary, I have obtained a great grace for you from my Son. Your life will be spared for a few more years. See that you spend these years wisely, and do penance.”
When the King regained consciousness he cried out: “Blessed be the Rosary of the Most Holy Virgin Mary, by which I have been delivered from eternal damnation!”
After he had recovered his health he spent the rest of his life in spreading devotion to the Holy Rosary and said it faithfully every day.
People who love the Blessed Virgin out to follow the example of King Alphonsus and that of the saints whom I have mentioned so that they too may win other souls for the Confraternity of the Holy Rosary. They will then receive great graces on earth and eternal life later on. “They that explain me shall have life everlasting life.” [1] Ecclus. 24:31”
Another story on how saying rosaries can earn you salvation:
“Later on, when she was at prayer she fell into ecstasy and had a vision of her soul appearing before the Supreme Judge. Saint Michael put all her penances and to her prayers on one side of the scale and all her sins and imperfections on the other. The tray of her good works were greatly outweighed by that of her sins and imperfections.
Filled with alarm, she cried out for mercy, imploring the help of the Blessed Virgin, her gracious advocate, who took the one and only Rosary she had said for her penance and dropped it on the tray of her good works. This one Rosary was so heavy that it weighed more than all her sins as well as her good works. Our Lady then reproved her for having refused to follow the counsel of her servant Dominic and for not saying the Rosary every day.
As soon as she came to herself she rushed and threw herself at the feet of Saint Dominic and told him all that had happened, begged his forgiveness and promised to say the Rosary faithfully every day. By this means she rose to Christian perfection and finally to the glory of everlasting life.”
