You've raised some good points here that would naturally lead to the subject of euthanasia....
It hurts. We've never done it before. Yet, some say that we were dead before we were born.
If non-existence = death then I guess so. Before our parents' DNA got mingled...we did not exist. Just as Adam did not exist before God created him.
50 year olds look at the feeble, and say that they'd rather die than go on (crippled, blind, etc). But when they reach 60, they realize that life is still worth living even with some debilities.
As one ages still more, there is little to look forward to except long term care nursing ($25,000/month), often with nurses who don't clean poop and pee for 24 hours, don't respond to nurse call buttons. At that point, death is not such a disappointment, land it is the inevitable end.
Having gone through most of those phases, I can identify....and having had a loved one in care I have experienced what that means as well......
But it is clear that the Bible is correct....we were never meant to die and leave, or lose loved ones. We have no 'program' for death. Nothing can sooth the pain of a loss, that some never get over. It is a pain that goes on stabbing the heart year after year. But when life has become something that is not worth enduring, then who are we to expect those loved ones to stay around longer than they want or need to?
I am not a proponent of active euthanasia although it has its positives in certain circumstances...the negatives at this time outweigh those positives. Life was not meant to end. We have a deep desire within us to go on living, and as you said...even in difficult circumstances this is the case.
The family member who was in care was completely disabled and bedridden.....he decided that it was time to end the painful indignity that his life had become, so he simply refused to eat and drink. He had the full support of his doctor who administered pain relief during the process with an automated syringe driver. No one can force you to do eat or drink. And if you have signed a DNR order, they cannot legally "save" you once you are unconscious and your wishes are down in writing.
It was not an unpleasant experience overall because...
1) we knew that he had lost all desire to keep living with his terminal illness and this was his decision.
2) What he chose to do is called "passive euthanasia" meaning it breaks no law of God or man to end your own suffering.
3) It gave the family wonderful time with him, as we stayed for the whole time it took him to pass away, which he did very gently. We had his favorite music playing in the background and we shared all the old photos of his childhood and we were there with him and for him during the whole process.
4) It gave us closure to have shared that precious time with him....but the pain of loss remains.
Another aspect of passive euthanasia that never seems to be discussed is induced coma. When someone is nearing death and the final weeks are approaching, why are the dying not given access to a painless death? Why can't they induce a coma (only at the patients request in writing) and ease them into "the long goodnight" painlessly? There is just so much that morphine can do in those final weeks. Why must they die in agony and distress? Who benefits? I have had friends with cancer asking me to pray for them to die......it is heart wrenching.
Theists like to believe that they live on. Atheists don't believe in God, and have no reason to hedge their bets (in case there is a God). But, if someone guessed wrong, and picked the wrong jealous God, they don't have a prayer in heaven.
I have no belief in heaven as the final destination for all believers, except for the "elect" or "the chosen ones"......these have a specific role and purpose in heaven (Revelation 20:6) and they will assist Christ Jesus in the administration of his heavenly kingdom over earthly subjects, bringing us back to what we lost in Eden. (Revelation 21:2-4) That is my hope for the future....I will either survive the end times, or if I die before the end comes, I will be resurrected in the "new earth" (2 Peter 3:13; John 5:28-29) Either way, I am happy.
