The reason I ask your perspective: If you believe in creationism and chance evolution, there would be no reason to fret over others that are naturally weeded out. That's just evolution – cold science.
But if you believe we are more than just cells and chemical reactions, that someone is watching over us, then each of us has a mission, goal and a final destination. That mission may be short or long, but it's still a personal quest and journey. We meet and assist others on their journey, as they do for us.
If you view your survival as a gift, each day is another precious gift you can share with others to help them see that WE only have so many days on this planet. We are mortal -- each one of us.
But you may have an even greater mission: to help those who believe they are immortal, invincible, or oblivious to death. You may be called to teach and pass on the tremendous gift that life is. Give that gratitude to those who are without it. LIFE is special. You are proof of it.
You've been through the fire -- you have great compassion for those who have been with you. Their lives have impacted you. You have learned that people are more important than things. You have developed a friendship with and for those who have gone through the battle with you.
There are others that still need to learn that life is valuable, regardless of the length of days or hours. You can teach them. Share the gift that you are. Teach them that all life is worth living to the best that we are able. Teach, especially those who believe they have a long future ahead of them, to value each new day. It too is a gift.
Beautifully articulated.
