It's not worded just perfect, but it'll do...
"In the midst of my sorrow I called to the Lord, and he answered." -Jonah 2:2
I was diagnosed with cancer in 2008. I don't compare or pretend to understand the heartache you and your wife are going through, though. Learn to love every breath you take, don't discount telling the other everything's ok, and do something every now and again that brings an ear-to-ear smile.
Good luck and God bless.
I'm sure from each of us here, you're in our prayers.
