May God guide the Dr's hand, may you, Ernie, be at peace, knowing that nothing will come to you except what comes through God's hand first.
When my granddaughter was a baby, she had tortoculis, (not sure about the spelling) a condition of her neck which pulled it to one side, and caused much pain. The only thing that helped was our chiropractor. She was too small for the adjusting table, so the Dr laid her across her mama's lap and worked on her neck. Elizabeth never cried out, but when she was raised up, huge tears were standing in her eyes. But, as long as her mama had her hands on her, she felt safe. I never forgot that...and have applied it to God's care for me. As long as I keep myself in His hands, nothing will come to me, but that comes through His hands first. Remember that, dear Ernie, when you go into surgery. Praying for you.
