These Invocations to the Precious Blood of Jesus are an especially good way to acknowledge Christ’s sacrifice for us at Calvary. Each of them make good short prayers that can be easily memorized (also known as Aspirations). And together they form a touching and timeless prayerful tribute to our Lord’s saving graces 2000 years ago and today as well!
They provide some moving material for meditation on His Passion, as well as on our need for His love and mercy as we seek to do His will.
The line about the Sacred Heart of Jesus reminds us of a well-known devotion to our Lord’s Sacred Heart in mentioning that wondrous event when Longinus thrust his spear into our Lord’s side upon His death and blood and water flowed out (John 19:34).
When we read of dying to self-love, incidentally, this does not in any way contradict the one of the two Great Commandments Jesus referred to in his words to a Scribe to love your neighbor as yourself (SOURCE). This refers rather to the kind of concupiscent "me first" kind of selfish love we all fall prey to at one time or another.
We get a wonderful sense in some of these lines of the life source and force that is Jesus' Precious Blood. And the beauty of this is that His Precious Blood was not just depleted from His Sacred Body on our behalf almost 2000 years ago in His ignominious crucifixion. We can partake of it as Baptized Catholics in a state of grace free from mortal sin in the host we consume in Holy Communion at Mass!
The final line makes an especially good Aspiration you can say at any time of the day to help the Church as well as yourself and your fellow sinners!
