I think munchkins are special because they are the shape of fun - sweet little balls of dough joy! The original donut is also fun in its own right, being round as well with a happy little hole in the center. What separates typical donuts from the kinds with cream or jelly filling and other pastries is the hole. That hole is what makes the donut awesome! The dough ball from which the hole was created would be no fun at all had it never been removed!
What I make of the donut/life analogy: if you want to have fun with life, remove Jesus and eat him separately. (^_-)
So, about the 'hole in the middle of our hearts' ...? I say, what of it? Jesus won't fill that hole unless you really want him to. For some people, art fills that hole. For others, music. There is always more than just one hole, too.
Christians, don't kid yourselves - filling it with the idea of supernatural love instead of that unsatisfying worldly stuff does not set you apart. It makes you the same as everyone else, only with the addition of an inflated ego to go along with your choice of filling. Not to mention the ultimate denial of that ego, as you hide behind the idea of a supernatural god, expressing your own fear and desire in the form of his love or judgement.
No matter what you fill your hole with, there will always be another. When you fill it with God, it just becomes natural to believe that future holes are simply 'moments of weakness'. You fill it with the same old stuff after each weak moment and it becomes a comfortable pattern for you.
It may feel nice to be comfy cozy, but you can't make a discovery unless you test your limits. For that, you must go out and explore. You may feel at times as though you are in fact exploring, but 'journeying' while locked inside the same frame of mind is kind of like painting the walls or rearranging the furniture. To journey, you must be willing to think outside the box your mind urges you to stay within.
There is always something new to learn about yourself within these holes and the possibilities are endless. Holes are naturally scary - we just can't stand the idea of not knowing what 's at that bottom. On some level, we'd all rather rely on a satisfying idea that has no evidence than go through life not knowing the answer or if we'll ever figure it out for sure. Where would we be as a whole if everyone gave into this fear? Isaac Newton, Einstein, Christoper Columbus (even if he was an asshole, he did question and crush a set belief) and even the evil Darwin?
It is only natural to be a little uncomfortable or even scared of these gaps in our understanding. It's a sad thing to let that fear rule your life and even sadder to try and push it onto others. To then view anyone for expressing a curiosity and willingness to face the world as inferior seems to be the next step, which is just backwards and quite simply, bullying. Why all of that? If you stick with the uncomfortable stuff and face the scary feelings, the journey can be fun and discoveries, deeply satisfying. No, it doesn't soothe your fear or your ego, but if you wait it out it can do so much more!
I don't know about you, but I am at peace with my holes - and that's without Jesus!
