Mense Maio §14

¹⁴ You should know that We are relying particularly on the prayers of children and those suffering affliction, for their pleas have special power to penetrate heaven and soften God's justice. Since this is a perfect occasion, do not fail to put repeated emphasis on the recitation of the Rosary, the prayer so pleasing to Our Lady and so often recommended by the Roman Pontiffs. It affords the faithful an excellent means of complying effectively and pleasingly with our divine Master's command: " Ask, and it shall be given to you; seek, and you shall find; knock, and it shall be opened to you .
