Paul said in 1 Corinthians 15:26 “The last enemy that shall be destroyed is death”. Yet without death, wealth and power would continue to accumulate in fewer and fewer immortal hands, and old ideas would never give way to new ones. Without death, people would not feel the vitality of living that the very brevity of our life stimulates, and the Earth would continue to fill up with people until everyone was eating those funny green graham crackers Charlton Heston found out about in Soylent Green.
Whether death is destroyed now or at the end of time, it is not really our enemy, no more than pain is our enemy. Pain is a defense mechanism, just as the fear of death is. People who cannot feel pain rarely live to be twenty years old, and those who feel we should wage a war against Demon Pain are as ignorant as those who mistake, as the slings and arrows of an enemy, the natural fear of death which is ingrained in all living things to cause them to avoid risky behaviors.
Look around you. Nothing in this world is meant to endure forever. Even the redwoods last for only 2,000 years, an eyeblink in the life of the Earth. In time the very sun will die.
Sometimes individual cells in your body decide they want to be immortal too (like five years ago when I had breast cancer) and they reproduce like crazy. They end up killing the whole body, and that squashes their little plan in the bud. Any species that became immortal would fill the Earth, driving out all others (just like a cancer), when it is the very diversity of life on this planet that makes life for any one species possible. Evolution ensures that the average life span of any critter on Earth is optimum for that critter. So take your 70 or 80 years and enjoy them.
Polarize to life! When did you never live?
Jesus said, “Which of you by taking thought can add one cubit unto his stature?” We cannot eliminate our fear of death and it is not really desirable to do so. But Jesus teaches us not to worry about death. And after teaching us not to worry about death in words, Christians believe that he died and rose to life once again to teach humanity that truth in a way that resonates directly in our soul.
