Working Purpose

What is the purpose to work? Are we working to survive? What is the purpose fo surviving? Survive to enjoy life? Too much question in my head. In fact, I am a christian. God is my creator, he suppose to know this answer. Sometimes before, he told me I exist because he love me. I know that he love me. That is good because he die for my salvation. Then what is good to live in heaven eternally? This is because it is bad to live in hell suffering by burning fire eternally. No choice, heaven is better obviously. Luckily, Jesus die for me. Hehe. Talk about it next time.
