Life in his hands

I have just finished a wonderful book “Life in his hands” by Susan Wyndham a true story of a Neurosurgeon and a Pianist. The neurosurgeon is the world famous Charles Teo, and the pianist is the late Aaron McMillan. This book I could not put down and in one incident on the operating table when removing a tumour of an apple everything goes wrong and then suddenly unexplained something happens where it all corrects and the operation proceeds to a excellent conclusion. Was this the power of God & prayer? Was it the power of faith? There certainly was no fear - I suggest to find the answer one should read the book.
