I just read the story of Caleb on the internet. I have stage four cancer. But I have no fear of death. Caleb did not strike me from the stories I read to have any fear of any thing. I would presume that would include death on Earth. I believe that Heaven is eternal. The hardest part now is the separation we all feel for those we love until it's our turn to join them in their bliss years from now. I truly look forward to meeting your son one day. God has blessed him.Make God bless you in your grief.
