Some of the promises of our lord for those who practice this devotion

Promises of Our Lord to Sister Mary Martha Chambon

At each word that you pronounce of the Chaplet of the Holy Wounds, I allow a drop of My Blood to fall upon the soul of a sinner.

I will grant all that is asked of Me through the invocation of My Holy Wounds. You will obtain
everything, because it is through the merit of My Blood, which is of infinite price.

With My Wounds and My Divine Heart, everything can be obtained.

My Wounds will repair yours. My Wounds will cover all your faults. Those who honor them will have a true knowledge of Jesus Christ. In meditation on them, you will always find a new love. My Wounds will cover all your sins.

In offering My Wounds for the conversion of sinners, even though the sinners are not converted, you will have the same merit before God as if they were.

A sinner who will say the following prayer will obtain conversion: "Eternal Father, I offer Thee the Wounds of Our Lord Jesus Christ to heal those of our souls", and that soul who during life honored the Wounds of Our Lord Jesus Christ and has offered them to the Eternal Father for the Souls in Purgatory, will be accompanied at the moment of death by the Holy Virgin and the
angels; and Our Lord on the Cross, all brilliant in glory, will receive her and crown her.

When you offer My Holy Wounds for sinners, you must not forget to do so for the souls in Purgatory, as there are but few who think of their relief . . . The Holy Wounds are the treasure of treasures for the souls in Purgatory.
