Desperate prayers needed!!!

Hello everyone I know that I just posted a little bit ago but I just heard from one of my friends that her father is in need of serious prayer!! This is the message that my friend sent me: "My Dad goes in tomorrow morning (scheduled for 8A) for cardiac catheterization to try to open the 100% blockage. We pray that major surgery will be avoided. If it goes well and quickly, they will also do the 80% one; otherwise, that will be done another time.Please pray for healing and peace for my Dad, for wisdom and skill for the doctors; and for strength and peace for our family. Thank you." So for those of you that believe in the power of prayer please lift this family and this man in prayer.
