Ah, the End. My offspring’s current obsession with Minecraft has led him to discover a portal that will bring him to “The End”. So, today, let’s hop that portal to our own potential “end”...
Taking a step back, and looking at all those verses together, my belief is that “the biggie” sin is more of a process than a single act. It is the process by which we become calloused to God and all His creation, through vanity and self-righteousness—which would allow us to foster anger and all its bitter fruit to the very end.
In The Story We Find Ourselves In, McLaren proposes what a conversation between God and the ultimate navel-gazer would look like:
Neo says,” [...] I tried in every way possible to get through to you, but you wouldn’t respond to my grace. Even if I forgive and forget all the bad things you have done, is there enough of your character left for you to continue existing in my new creation? And would you even like living with me in a story you have avoided, minimised, resisted or subverted all your life?[ [...] I feel regret about what you could have become, but didn’t. I wish you had given me more to work with, but you haven’t. Your story has been a tragedy of waste and missed opportunities.” (p. 167)
Note the “Would you even LIKE living with me in a story you have avoided...all your life?” This person would not have engaged in learning the culture Heaven here on Earth—not learning about a self-giving love, or refusing the vulnerability of the intimacy of Heaven.
"It depends on the way you are using the words. If they leave that grey town (i.e. Hell) behind it will not have been Hell. To any that leaves it, it is Purgatory. And perhaps you had better not call this country Heaven. Not Deep Heaven, you understand. You can call it the Valley of the Shadow of Life.”
Oddly enough, in these images, it is almost as if we choose our end, although we believe God to be the great judge. We face Him, we are measured by His pattern, and we respond yea or nay. Ultimately, those of us who don’t “make it”, chose to no longer hold onto any redeeming bits of self, and are then left to our own devices—forever.
