Praying for a Miracle

So one of my friends is going through a really rough time. Just recently she and her brothers found out that their mom may pass away any day now. Her mom has been fighting cancer for the last few months. This family has been experiencing alot of hard times in the past year. If there is one thing i would ask you to do, its pray for complete healing in the face of death. I believe in the power of faith led prayer. Thanks
