Fleur de lis = the beauty, status of mother Mary....
Someone showing their adoration towards her and what she is and what she stands for.
It seems someone of one background, and has been converted, wishes to strike a deal, (in a most reverent and matter of fact way) an idea for Mary, to consider as a plausible prayer to answer (shows that there are so many religions, - why not one of their own), one that would adore mother Mary, and give the one in prayer to her something they are in long mourning over, a lost love, a child, family, friend etc. ...
Daddy was a one-shot deal, meaning the creator, who we named god (the father- daddy) was indeed a one-shot deal, we are created by him and shall always be him, and shall always go to him in any form, so .... The prayer states, that we know not to worry, there is no "seven seals" coming to do us in and flank us out into darkness. We came from love, the song is of love, so we return to love.... So until then mother Mary, let us work in communion with each other, this is my heart's desire, and it is good... Knowing you can never fully return to your 1st belief system, and that your 1st belief system will not give you back your baby (lost your powers of your 1st belief system when you converted), then might as well try what one may with the new belief system to reach your greatest wish/unanswered prayer...savy...???
