Incredible are the numbers of people brought together to try to help Terri and to pray. I think I'll start one. Feel free to jump in if you wish.
Our Father, who art in Heaven,
Hallowed be Thy Name,
Thy Kingdom Come, Thy WILL BE DONE
Dear Lord I pray for Terri's healing, but given that she has not been healed in 15 years I pray that your will be done.
Whether it be that she remain in this horrible state or be liberated from it to come home to be with you...YOUR WILL BE DONE.
