That sounds a little bit like the soul building theodicy I’ve heard. But my problem with that answer is, if we assume we lived in a world where we did go straight to heaven, one could ask why we don’t spend our beginning 80 years of eternity in a place with varying degrees of suffering. That person could be answered in the same way: if that were the case, we wouldn’t be who we are now. To me, it doesn’t seem like it actually answers any questions.
