The LORD is My Shepherd

I'm scheduled to have surgery on my right hip tomorrow. Instead of thinking about things that could go terribly wrong, I'm choosing to reassure myself, as David did centuries ago, by reminding myself that the LORD is my shepherd. He is the one who guards me, cares for me, provides for me.... I will trust Him to be with me and to provide all I need during the surgery and during the months of recovery. 

Since He has faithfully tended me all my life, why would I doubt Him now?
