The Prayer of Faith!
My wife, Mely, and I will pray for your sister this morning, during our morning devotion. We spend about an hour studying our Bible everyday and we pray for those we know about who are in need of a special touch of healing from God. I myself, was healed of a severe slipped disk which nearly immobilized me from the neck down with excruciating pain, many years ago and we have experienced others who have been healed in our presence by our good Lord Jesus Christ, in His name. God bless you and your sister and may He fill your sister with the presence and power of faith for her own healing.
