Godspeed Mark. Your battle against cancer is over, live on in peace.
Marie, my sincere condolences in your loss. I never had the pleasure of meeting Mark, clearly that is my loss. There really are know words of support that any can offer, but please know that those that have walked your path know the vacant feelings of loss that you feel.
God has plans for all of us. Often those plans include tests that we only understand as the years and pain recede.
