What occupational possibilities will there be in the hereafter given by the Creator when...?

Well, first of all the way to be saved and know God is to repent and receive Jesus as Savior and Lord of your life(if you haven't already), and He will come into your heart and save you by His grace. The Bible teaches that there will be rewards in heaven for our faithful service to Christ here on earth. Also, the Bible teaches that there will be different levels of responsiblility in heaven based on how faithful we were here on earth. Exactly what we will do in heaven I don't know, but I know we will eat food. We will probably sing worship a lot, and I don't know what else. Talk to God, talk to the angels and other people, maybe build things, do landscaping, make art and music to worship God, and i'm sure many other things that are much more wonderful than we can imagine.
