Imagine an elaborately designed machine. It is huge and parts of it run through every household. As in, everybody in the world has access to observing--an albeit miniscule--portion of the machine. No one can see the whole thing at one time, but can see tiny parts of it, within their own homes or different sections, when they visit others in their homes.
Also know that every single component of the machine is absolutely necessary for the final, complete perfect running of the thing. As in, there is not one superfluous part. Nothing can be removed or altered from the object (the machine) which won't change its intended purpose. Nothing. Each and every part, whether it looks merely decorative or obviously integral or not, MUST remain or it won't function properly, as intended by its designer.
Now, regarding the designer . . . he knows precisely what he is doing. He is the greatest genius ever and has exactly created his machine to produce perfectly the end result he desires.
But immediately, upon installation of the device, the people through whose homes it runs, begin to question it. They cannot see the whole thing and do not understand its operation, but when they look at various of its individual parts they think, "What in the world is this? Why is this part here? It looks unnecessary," and they begin to tinker.
Many even fancy that something is wrong with the machine. They cannot see the end result or how it all works together, but looking at the small portions in front of them, they think, "I could do better than this? What is this thingy here? And what does that do? Why is it not constructed this way? Why did he put this part there? I wouldn't have done it like that!"
Despite the machine running absolutely as designed and destined to produce its desired result, many people become skeptics and critics and form committees and clubs, combining their complaints and ideas, with the intention of changing the machine to what and how they have imagined it ought to be done better.
Which is absurd and ridiculous, as none of them--and not even all combined--have even the most infinitesimal fraction of the required knowledge it would take to adjust even one part without the whole thing then breaking down and ending in disastrous ruin.
But, in their myopic, small-minded vanity, they continue to tinker and twist, alter and pervert the machines design, and the more they do, the more it seems to misfire, clank, cause problems and run improperly. This doesn't stop them though and in fact they organize new committees and panels to address the new problems, all the while blaming (the problems they just made) on the original designer.
What they don't know is that the designer is so brilliant and far-seeing, that he took all this into consideration beforehand. He knew there would be trouble-makers and that everyone would be confused and uncomprehending when viewing only the limited parts of the machine within their respective views. . . . And he knew they would fiddle with and damage its components in their ignorance and hubris. . . . So, he ingeniously constructed the thing so that, even when people meddled, their crude alterations did not actually harm the device (though it looked like it for a while) but instead became another part of the intended design so that, at last, it produced its intended end more fantastic, beautiful, glorious even, than ever anyone (but he) could have imagined!
This is a (admittedly rough) picture of what it is like when we question why God does things this or that way. We only see a teeny, tiny fraction of what He has in mind--what He has purposed for His creation. We cannot see how it all fits together--how all the various, nearly infinite parts work together for the final result He intends. We look at some element that happens to be within our proximate view and, not comprehending how it relates to another element maybe three counties over, we argue against it, though both are inextricably linked and vital to each other's operation within the whole.
The vastness and intricacies involved with creation and creatures . . . with personhood, life . . . are such that it is laughable and not just a bit pathetic, that we ever feel inclined to critique or imagine to improve what God does and has done.
This was the first sin--questioning God, the Designer--and imagining to know better or doubt how things ought to be done--what might be permissible or not to alter from His original, divine commands. Bottom line it is love and infatuation of/with self MORE than love and infatuation of/with God that initially leads astray and continues to with us this very day.
