In Luke 19.11-27, Jesus tells a parable about "when the kingdom of God appears." Many people believe that he's talking about heaven and hell. In the story, people in "heaven" are rewarded with jobs and responsibility, much like we have here on earth. Since the book of Revelation describes heaven as being on this earth (Rev. 21.2), and it describes heaven as a city (Rev. 21.10), it makes sense to me that life in heaven will be filled with productive labor, meaningful activity, and lots to do. It certainly won't be sitting around playing harps. That would kill any of us. :)

Watchman Nee wrote, "Heaven is not a place of inactivity, but we shall be called to a greater work." The reward for responsibility is more responsibility. To him who has, more will be given.

Isaiah 65 makes it sound like people will build houses (v. 21) and do work that is productive and fulfilling (23). Zechariah 14.16 makes mention of worship, as does much of Revelation. Matthew 25.14-30 also mentions "I will put you in charge of many things."

In a speculative vein, what if God starts creating again (since it is his nature), and there are more worlds to explore, and new worlds to explore, and every day something new is popping up (since God is infinite in his creative nature) to do, see, and enjoy?

To those who believe in an afterlife, what do you literally think you will be doing in heaven? When I was young and still Catholic I always figured heaven would be fun where you can just do whatever you want and have whatever you want. Then I realized the official teaching was that you would be praying or worshipping god all the time. Having to worship something for eternity sounds a lot more like hell than heaven to me, so I was just wondering what you thought you would actually be doing "day to day" I guess in heaven.
