We know there will be no money in paradise. But there will almost certainly be jobs to do. We will be perfect at our jobs but that doesn't mean we will be perfect at every job. People will still be unique and will pursue and become skilled at those things of interest to them. We will trade favors. Perhaps you may repair a brothers roof and in exchange he will landscape your yard.
It led me to imagine what the resurrected men from the bible will be interested in!
Just imagine having your roof repaired by Elijah or Moses! Or having a new chair or cabinets built by Noah! And then preparing a meal for them!
Such good times ahead.
