I've read that when a wife loses a husband she is called a widow. When a husband loses a wife he is called a widower. A child who loses his parents is called an orphan.
But, Righteous Father, there is no word for a parent who loses a child.

Abba Father, hear this mother's cry of anguish. LORD, please hasten to manifest Your presence to her. This mother is suffering the ultimate deprivation, and she needs Your Great Comfort, knowing, Only Your healing love can breath life again into the devestated body, heart and soul of this precious woman. Only Your Comfort, dear LORD can fill the deep void in this mother's life. Only You, LORD God of Hope, can strengthen this broken life and enable her to rise up and overcome by the "Blood of the Lamb, and The word of her testimony, glorifying You as she rejoices, resting in Your love.
Abba Father, we ask that everything the enemy has used to destroy this woman's life, You will use for good to Your glory. May these blessings then enable her to comfort her own heart as they establish her in every good word and deed. Amen and Amen
