Why does it matter what you train for now? Does that mean you can't build things in the "new system" if you trained as a lawyer. I thought we had forever to learn everything, retraining should be easy especially if we are perfect.
Tight pants Tony knows better than Jesus. Luke as a physician should never have been picked by Jesus. In fact as far as I am aware none of the apostles should have been picked, you don't need tax collectors or fisherman in heaven or even on a paradise earth as we presumably won't be eating fish.
Of course none of these things they promise exist anyway so we might as well make the most of what we have now and not worry about what skills we need after Armageddon.
