Consider: At the point the prodigal woke up and decided to return home, he was still in the Kingdom, as he was at his lowest point tending pigs and even after he returned and was welcomed in glory. It's all Kingdom, bliss and ignorance, suffering and saturation. Perhaps the path home took longer and was filled with even more danger and adventure than scripture reveals. Perhaps the path didn't end at home. Perhaps there never was a path after all. Perhaps it is all path. Perhaps returning home is no more or no less than the end of conflict--conflict with the source of family, with the source of pleasure, with the source of pain, with the inevitability of return, with the path itself, with the source of source.
I feel that any true path ultimately leads us back to where we started. I have found there is nothing to find that wasn't already. That doesn't mean the searching wasn't worth it. It doesn't mean we know everything, or anything. It doesn't mean we stop wandering. It means we can always rest at home, having never really left. And if anything is to be gained from it all, it's the eternal ability to always rest at home.
