Petition to the Miraculous Virgin. Very effective prayer to the Madonna

O Immaculate Virgin, we know that you are always and everywhere willing to answer the prayers of your exiled children in this valley of tears, but we also know that there are days and hours in which you take pleasure in spreading the treasures of your graces more abundantly. Well, oh Mary, here we are prostrate before you, just on that same day and now blessed, chosen by you for the manifestation of your Medal.
We come to you, filled with immense gratitude and unlimited trust, in this hour so dear to you, to thank you for the great gift you have given us by giving us your image, so that it could be a proof of affection and a pledge of protection for us. We therefore promise you that, according to your desire, the holy Medal will be the sign of your presence with us, it will be our book on which we will learn to know, following your advice, how much you have loved us and what we must do, so that many sacrifices of yours and your divine Son are not useless. Yes, your pierced Heart, represented on the Medal, will always rest on ours and make it palpitate in unison with yours. He will light him with love for Jesus and fortify him to carry his cross behind him every day. This is your hour, O Mary, the hour of your inexhaustible goodness, of your triumphant mercy, the hour you did flow through your medal, that torrent of graces and wonders that flooded the earth. Do, Mother, that this hour, which reminds you of the sweet emotion of your Heart, which prompted you to come to visit us and bring us the remedy for many evils, make this hour also our hour: the hour of our sincere conversion, and hour of full fulfillment of our vows.
You who promised, just at this fortunate hour, that the graces would have been great for those who asked them with confidence: turn your glances benignly to our supplications. We confess that we do not deserve your graces, but to whom will we turn, O Mary, if not to you, who are our Mother, in whose hands God has placed all his graces? So have mercy on us.
We ask you for your Immaculate Conception and for the love that led you to give us your precious Medal. O Comforter of the afflicted, who already touched you on our miseries, look at the evils from which we are oppressed. Let your Medal spread your beneficial rays upon us and all our loved ones: heal our sick, give peace to our families, avoid us from any danger. Bring your Medal comfort to those who suffer, consolation to those who cry, light and strength to all.
But especially allow, O Mary, that in this solemn hour we ask you for the conversion of sinners, especially those who are dearest to us. Remember that they too are your children, that you have suffered, prayed and cried for them. Save them, o Refuge of sinners, so that after having loved you all, invoked and served you on earth, we can come to thank you and praise eternally in Heaven. So be it. Hi Regina
