A "Heaven" for Those Unwilling to Change

After a good deal of thinking about it and some time spent talking about it with others, I think I've figured out at least one way it's beneficial to us for God to let us sin: It lets us be ourselves.

Granted, there's a big difference between being ourselves as we are now and being our best selves, the selves we could be, and the latter is definitely preferable. Furthermore, in terms of the extents of the blessings involved, qualifying for the Celestial Kingdom is far more beneficial than ending up in the Telestial Kingdom. But even the Telestial Kingdom isn't a terrible place to end up (apart from the opportunity cost), and qualifying for the Celestial Kingdom comes at a cost as well.

To become Celestial, we need to change. All of us are less than perfect, so to live in a perfected state, we need to be willing to change for the better, and some people aren't. Change is uncomfortable and undesirable to some people. Some people don't want to become perfect, and they probably wouldn't feel comfortable in an afterlife with people who do, so God made another place for them - a place where they could feel comfortable with being themselves.

Of course, it's entirely possible that this isn't actually a reason why God lets us commit sin. There may be another explanation for how God can allow sin to happen while "all that He does is for our eternal benefit." It's difficult to imagine an "eternal benefit" to committing sin, but if we take "eternal" to mean "lasting forever," and if we allow "comfort" to be listed as a kind of benefit, this explanation sort of works. It'd still be nice to find a better explanation, but I can be satisfied with this one for now.

But that doesn't mean that we should be satisfied with the way we are, not even "for now." We should frequently strive to improve ourselves so we can qualify for greater and greater blessings, as that would, in my opinion, be most beneficial to us. Still, there are some who feel that changing for the better is too great a price to pay, and for those who deeply, sincerely feel that way, it may be kinder for God to give them a lower kingdom to live in than to demand that they make the change.
