I am a christian and this is just my summation of what I believe based on what I have learned in scripture and in living a life as a "born again" christian. I believe that God made us for His Pleasure. Also that He wants an actual relationship with us. He enjoys and desires fellowship with His creation. And, that He made us in His own image, that while we are flesh, that flesh will one day die and our spirit will remain with Him forever, still in fellowship and togetherness when we have been "born again" through Jesus after sin had taken it's place in the world. In the Garden of Eden, he fellowshipped with them, blessed them, was Loving and kind. They were comfortable with God. He even wanted them to multiply and have more people to enjoy and love and fellowship with. So much, He wanted that, I believe, that He made a way for us to be reconciled back into fellowship with Himself when we got separated. And, I believe that we do learn in this day some specifics about our life and God's plan for each individual life as we are in that fellowship in this present day. We, of course, are not still in the Garden of Eden, but there is fellowship...through His Word (more below)
Depends. Religious purposes are mostly crap. Some people might go on about fate and crap. You could say the purpose is to enjoy life or to contribute to society. However there is no actual purpose that we can possibly know of.
I believe everyone has a different answer for this. My best advice is to look with in yourself and ask yourself the same thing. Whatever it is you feel you were put on this earth to do, be, or experience then go for it! I honestly believe my purpose in life is to be a mother...I don't have kids yet but want them more than anything in this world. Good luck on your journey to the answer =)
The purpose of life is summed up in Proverbs 3:5,6 "Trust in Jehovah with all your heart and do not lean upon your own understanding. In all your ways take notice of him, and he himself will make your paths straight." If our heavenly father gave us life, then he deserves our love and worship.
