Many of you will remember with me the epic TV series Mission Impossible which chronicled the adventures of the Impossible Mission Taskforce, a team of government spies and specialists who were assigned "impossible missions" by the unseen "Secretary". If not, you may have seen the more recent movie of the same title. If not, well, bear with me. I think you'll get the point. In the original series, the Team Leader (Dan Briggs the first season, then Jim Phelps the other six) was always given a mission, usually involving the impossible (hence the title) task of disarming an alarming situation within a time limit (inevitably by the end of the show). If you've read any recent news regarding the science of aging you may know that the government and other organizations have amassed similar teams of specialists today and tasked them with a similarly serious and seemingly impossible mission, to seek out and find scientific answers to the secret of everlasting life. 1 The primary premise of most of these teams of specialists is that our bodies are of faulty design and contain many individual "time bombs" (e.g., faulty organ systems) that are doomed to eventual failure. Some very intelligent people are claiming that, because of an exponential increase in human knowledge related to the science of aging, we will soon be able to take control of and even halt the aging process by defusing these internal time bombs. Given the intriguing prospects of this mission, many Americans and people all over the world are taking stock, both literally and figuratively, in the work of these scientists. Can death be conquered by a taskforce of specialists armed with incredible intelligence, strong determination and ample funding? Are these the ingredients for everlasting life? Let's take a look at some scientific and Biblical reasons why it may or may not be a good idea to put faith, hope and funding in the hands of these individuals.
Is there any merit to the claims that the fountain of youth can be obtained through science? The fields of these specialists are seeded with many grains of truth. After all, single-celled creatures like bacteria don't die of old age, but continue to divide into two new copies, each of which divides into two more, and so on. Humans have organs such as the liver and kidneys that are made of many individual cells. Why don't these cells keep on dividing, repairing and renewing our organs forever? True, the Second Law of Thermodynamics dictates that all fixed structures will eventually wear out. However, biological organisms are not fixed structures, but contain built-in repair mechanisms. Even from a Biblical perspective, it is reasonable to conclude that these repair mechanisms were once sufficient to allow humans to live nearly 1,000 years (see Genesis 5). Why not longer, if God should ordain it so? Indeed, though an average "upper limit" seems to be programmed into each species alive today, breeding experiments have shown that this limit can be altered, even dramatically. Experiments with fruit flies and worms have shown that extra longevity can be bred into and out of populations. A genetic switch involved in longevity has been identified in a species of worms and it is likely that such switches exist in humans as well. 2
Currently, and for the past 3-4,000 years, our organs wear out within a period of 100 years. 3 It is well known today that ordinary human cells will only divide some 80-90 times, then stop. However, there is scientific and Biblical basis to believe that this was not always so. On the tips of each of our DNA chromosomes is a structure called a telomere. It is apparently a counting device, with a number of beads on the end. Every time the cell divides, it is as if a bead is "snipped off," shortening the telomere. 4 Once all of the beads are gone, cell division can no longer take place. From then on, as each cell wears out, it is not replaced by any new ones and the organ system will eventually die. Thus, the answer to the question of whether the mission of these scientists is solvable appears to be yes, at least for God.
What's the Harm in Trying?
In a recent interview 5 and in his publication Fantastic Voyage: Live Long Enough to Live Forever 6 56 year-old inventor and computer scientist Dr. Ray Kurzweil urges people to take care of themselves and live long enough to benefit from a coming explosion in technology that he predicts will make infinite life spans possible. He believes that we will one day be able to inject ourselves with millions of blood cell-sized robots called "nanobots" that will swarm throughout the body, repairing bones, muscles, arteries and brain cells. He believes that we will also be able to download improvements to our genetic code via the internet. Dr. Kurzweil has credibility. He did, after all, win the prestigious $500,000 Lemelson-MIT prize and the 1999 National Medal of Technology Award. The Christian Science Monitor even called him a "modern Edison" and he was inducted into the Inventors Hall of Fame in 2002. He says that his predictions are based on carefully constructed scientific models that he has used in the past to predict the development of the internet and computers that can beat a chess champion. 7 Dr. Kurzweil's current passion, or "mission" if you will, is to cross the three bridges that he says will lead to immortality. The first bridge is a healthy lifestyle. As part of a daily routine, he himself takes 250 vitamins and supplements, 8-10 glasses of alkaline water and 10 cups of green tea. The second bridge is gene control that will, as has been demonstrated for fruit flies and worms, remove disease causing genes and introduce genes that slow the aging process. The final bridge is nanotechnology and the introduction of nanobot "janitors" into our bloodstream.
Even if this mission of Dr. Kurzweil's and others turns out to indeed be impossible, some may ask "where's the foul?" What harm is there in allowing this perhaps a bit narcissistic but potentially useful intellectual pursuit among a select group of brilliant men? In the process of seeking their own immortality the technology they develop might do a lot of people good. However, the danger is that their mission would impede the greatest and most important mission of all time, the great commission, by making many less receptive to the most important message they will ever receive, the Gospel of Jesus Christ. The very idea that human technology can overcome death takes away the whole reason for the Gospel message and the need for a savior and lessens (for some) the need for a loving God. According to the Bible, death is a penalty for our sin and there is only one way to remove that penalty, through belief in Jesus, who died on the cross as a substitute for our sin. "For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord" (Romans 6:23). Jesus is the one and only reliable answer to defusing the ticking time bomb that is death, for he has promised to trample this last enemy under His feet when he returns. "For he must reign, till he has put all enemies under his feet. The last enemy that shall be destroyed is death" (1 Cor. 15:25-26). Further, Jesus is the one and only bridge that must be crossed to obtain not only eternal life, but eternal life in the presence of our loving God and creator. Despite what scientists may tell us about the benefits of healthy living, gene control and even nanobots, impossible missions require sensational miracles. And sensational miracles are only reliably administered by an omnipotent, omniscient, and omnipresent God, not an Impossible Mission Taskforce nor any other form of human intelligence.

In Psalm 90:10 we read "The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labor and sorrow; for it is soon cut off, and we fly away." This declares man's average lifespan to be seventy to eighty years. Today, over 3,000 years later, our average lifespan is essentially the same.
