Sister Mary Martha Chambon
Mary Martha Chambon (1841-1907) was a lay Sister of the Monastery of the Visitation Order in Chambery, France.  During her life, Jesus Himself is said to have revealed to her the following two invocations, giving her the double mission to adore and invoke the Sacred Wounds unceasingly and to revive this devotion in the hearts of creatures.  She died in the odor of sanctity on 21 March 1907, and the cause for her beatification was introduced in 1937.

Eternal Father I offer Thee the Wounds of Our Lord Jesus Christ to heal the wounds of our souls. My Jesus, pardon and mercy through the merits of Thy Sacred Wounds.

Here are some statements Jesus is said to have made to Sr. Mary Martha about this devotion:

"Come to My Wounds with hearts burning with love, and make the aspirations with great fervor that you may obtain the graces and favors you desire.  Come to this wound in My Side; it is the Wound of Love from which issue flames of fire" "You must pray that the knowledge of My Sacred Wounds may spread in the world".
