Tom,
It's good that you understand the posts dont equal the prayers provided or said... I know many who just don't post but pray.
On the other hand, I've benefited so much from coming here and being reminded of spiritual truths in my own struggles, I always want to pen a word or two.
May the Lord be with your mother, her team of surgeons and doctors and all who love her to guide all toward God's will for the outcome. May that outcome be one of healing, strength and renewal.
