Death blows, but what can you do? It was nice to believe that one day we would all be together, living forever in a perfect world. All we have loved that have been lost in death back with us. Now thou I think that is an unnatural thought. Plants, animals, ect everything dies. Pets can have personalities we have all seen that. Family pets can become part of the family, but we never expected them to be resurrected. Humans don't want to believe we are like everything else on this planet. Born into death. We want to believe we are better than everything else, always have. The stories of the God's are still passed down to us. To believe that death started because of 1 man sounds ridiculous. I believed in the Garden Of Eden Story as fact. Today, it just sounds like a story a parent would tell their little children. I'm glad I wasn't raised a JW. You can compare finding out lies about things you were taught from being a child. Finding out Santa was not real was devastating, but you got thru it. Finding out Death is it, at first can be overwhelming, but as time goes on you just accept it.
Some need that comfort believing that ones are in Heaven, or awaiting a resurrection, but when it comes to the time when someone looses a loved one in Death, that is the time you cannot judge ones beliefs. Everyone mourns in their own way, and what they have as faith or whatever is for them.
Death being described as unnatural is like saying the Sun disappearing every night is also unnatural.
