Having just encountered this question Can a devil use one prayer to prevent us from praying a different one
I encountered The Twelve Year Prayer of S. Bridget of Sweden
The first verse of the prayer is as follows: -
Our Father. Hail Mary. Eternal Father, through Mary’s unblemished hands and the Divine Heart of Jesus, I offer to Thee the first wounds, the first pains and the first bloodshed, as atonement for my & all of humanity’s sins of youth, as protection against the first mortal sin, especially among my relatives.
I am confused, how is a supplicant able to 'offer' these things? Surely they belong to God in the first place?
