Heavenly Father, thank you that you are my ever-present help in times of trouble. Please bless me I as undergo surgery. Your word says that you will never leave me or forsake me, and that you are always with me. Let me feel your presence with me during the operation. Please help me to trust in you, that you never stop watching over me and you are always working for my good. Lord, bless me and keep me, make your face shine upon me. Turn your face towards me and give me peace. Through Jesus Christ, our Lord, Amen.
