It's Ok, I'm All Right: How?

How can anyone who woke from an open heart procedure revealing a malignant tumor instead of a benign tumor pen these words, "It's ok, I'm all right?"
At age fifty-four I could confidently pen those words. My faith had already been through multiple challenges. Going through chemotherapy was not going to be easy. But, some of the other challenges I had faced earlier in my life weren't easy either. Was I disappointed? Greatly! No one looks forward to chemotherapy. The tumor had grown eight times its size. It had eaten into my heart, my vocal chord nerves and the nerves for my shoulder.
Some said, we just knew you would be healed. You were anointed at church. Had God let me down? No. My family and I could have gotten worse news. My faith still held. Eight years later I faced an even greater battle. This is my story.
