Well, I can't speak beyond my knowledge on this or for those of other faiths, however, for Christian believers there is HOPE! This Hope is why we cerebrate Easter, as this day signifies when Jesus arose from the grave/resurrected after having laid dead for three days! This HOPE is why, we need not be afraid of death and what lies beyond it. One of my dear friends recently received some terrible news about organ failure, which got them to began to question "What is the purpose of life if we will simply disappear and this is the wrong outlook according to what the Lord reveals to us through scripture. There is definitely a continuation of life, after death. Here's what I wrote. Praying that after reading, this will touch somebody...
The Bible teaches that "Man who is born of women is of few days and full of trouble--Job 14:1" So as imperfect, sinful humans we will face lots of strife in this life, however the good news is that Jesus paid that price...died and resurrected so that whosever believeth in him SHALL NOT PERISH, but have LIFE EVERLASTING--John 3:16!"
THAT IS REASON TO CELEBRATE! Most humans are scared of death and what lies beyond it (even those who do beleive in after life, but that's because as humans our brain really cannot fathom the unthinkable), but I believe that the life we are living on this Earth is only temporary...as God is preparing a place for us John 14:3. He's preparing special rooms and rewards for us! For those who believe, when they pass and the time comes they will be able to live out the rest of life with no more sorrows, no more pains, no more bad news about body organ failures or tragedies and we will get to spend it in peace and love with the very one who created us and all of our loved ones, family and friends. THAT'S REASON TO CELEBRATE!
So, please do not ever ask yourself what is the purpose of living if you will only disappear. We will not disappear. YOU will not disappear! Your legacy will certainly live on as time progresses while this Earth is still operating as we know it and even after we will all be reunited once again under much more joyous circumstances.
Do not let it get you down, depressed or confused. God has a purpose for your pain! I LOVE YOU SO MUCH!
