According to bible sin, suffering and death will end on Earth so then if there is no want for ANYTHING what would be one's purpose in life?

No. What do you think God created bed bugs for?

Isaiah 65:25 'the lion will eat grass like the bull' .  Do you think God will destroy bedbugs or make them just eat human dung or something  ? This post was edited by Kittigate at January 29, 2017 8:37 AM MST

So you are saying that the purpose in a human's life is to sin, suffer and die?  And without these life is not worth living? 

I am basically asking for what purpose life would be when sin, suffering and death ends and mankind will not want for anything. 

Things to do when sin, suffering, and death no longer exist on earth

1. Travel throughout the planet until you can say you know every nook and cranny.
2. Study every culture, and habits of every single inhabitant on the planet 
3. Learn the countless and too numerous to mention skills that exist.
4. Study human anatomy and specialize in each body part (organs, etc.)
5. Study ever species of animal life in existence  (on the ground, oceans, seas, rivers, lakes, etc.)
6. Study plant life
7. Develop natural talents God has endowed you with, ( example: athletic abilities, dance, voice, etc.)
8. Study technology 
9. Once you have learned everything you need to know about life on earth study astronomy and the never ending universe.
You will have eternity  (Titus 1:2)

Yes lots of interesting stuff to spend tons of time learning about.  I would prefer study of warm bodied live specimens specializing in counting the number of hairs in a certain area of the body especially those ladies you see sunbathing on the French Riviera  - if they would stay still long enough. 

To take a break from learning about all the stuff there is a never ending interest I could do things like seeing how many trillion years it would take to grow my beard long enough to wrap around the equator 3 times -different sorts of things to pass time...

It's about finding purpose in life, which at this point with life being so short it is simply not possible. There is a purpose for every humans existence, but most will never allow themselves the opportunity to find out. 

When I was born the Earth was short one person so my purpose in life  was fill in to make up for the shortage. 

O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!

God is very good at this God business. He says we'll like it.

Must mean eliminate politics,  religion and live in a socialist kind of society.

No police, no military..

Seems like there would be no real purpose in life;  just existing.  This post was edited by Kittigate at January 30, 2017 2:46 PM MST

My purpose would be an eternity of trying to give up my bad habits.
