They will surrender themselves to her, body and soul

God wishes therefore to reveal Mary, his masterpiece, and make her more known in these latter times. she is the dawn which precedes and discloses the Sun of Justice Jesus Christ, she must be known and acknowledged so that Jesus may be known and acknowledged. As she was the way by which Jesus first came to us, she will again be the way by which he will come to us the second time though not in the same manner.

In these latter times Mary must shine forth more than ever in mercy, power and grace…

Finally, God in these times wishes his Blessed Mother to be more known, loved and honored than she has ever been. This will certainly come about if the elect, by the grace and light of the Holy Spirit, adopt the interior and perfect practice of the devotion which I shall later unfold. Then they will clearly see that beautiful Star of the Sea, as much as faith allows… They will love her tenderly and will appreciate how full of compassion she is and how much they stand in need of her help.

In all circumstances they will have recourse to her as their advocate and mediatrix with Jesus Christ. They will see clearly that she is the safest, easiest, shortest and most perfect way of approaching Jesus and will surrender themselves to her, body and soul, without reserve in order to belong entirely to Jesus.
