I think we avoid talking about death because we don't want to offend or frighten others, such as children. There also seems to be an unspoken fear or superstition that by talking about death we might actually bring it on. Perhaps if we all saw our bodies as a "tent" it would not be so fearsome. Because to see our bodies as a "tent" is to recognize that they are just the "outer layer," a "shell." Our true self is the spirit man within. It is this spirit man that is eternal and will go to be in the presence of Jesus when our earthly bodies expire. We will shed these earthly bodies and go on to our true calling. Just as Peter talked of his "departure" or "exodus" so we too will go on to the promised home that Jesus has prepared for us. "Home" is afterall, where we all belong.
