Just heard from my dad--Brian's surgery went as well as the surgeons could have hoped it would.
He handled the surgery well (He's so strong & being made even stronger by a God who has answered so many of your prayers!), the spine is now fused, set exactly where it needs to be, & he's being transferred back into ICU. My parents hope to visit with him shortly.
This officially marks the beginning of the long road of rehabilitation & recovery. Brian's going to have a tough couple days where they'll go easy on him but it won't be long until the spiritual, mental, & physical work that comes with a recovery like this begins.
Thank you again for your well wishes & please be personally encouraged in the positive outlook for Brian's future & for help in your own hardships by Brian's strong witness that we know a loving God who answers prayer!
