Dear Father in heaven, go with me to surgery. Guide my doctor's hands so that his work may be done skillfully and quickly. As my Great Physician grant that all my trust may be in You and that I may have no fear.
Receive me now as Your forgiven child, and bring me safely through these next hours. In the name and for the sake of Jesus Christ, my Savior. Amen.
