FWers not only have a very difficult time in understanding and processing figures of speech (especially metaphors!) but they routinely ignore rhetorical questions because such questions gives a reader one of two choices for an answer and FWers don't like the correct answers. Jer 17:9 reads:
Jer 17:9
9 The heart is deceitful above all things, and it is exceedingly corrupt: who can know [understand] it?
ASV
The question at the end demands one answer: NO ONE CAN! Yet, GWH apparently thinks he has a great handle on the passage. He would have us believe that he understands it so well that he can just summarily dismiss the passage as being virtually irrelevant to us today since the text was just a Jewish "anomaly" -- a slight and rare blip in their history. But there are several things wrong with GWH's approach per the following:
1. He ignored several scriptures that teach that everything written in the OT applies to NC believers, is relevant to us, is to be taken to heart by us and this is why they were written for our benefit and instruction (Rom 15:4; 1Cor 10:6, 11; Heb 4:11; 2Pet 2:6; Jude 7).
2. The rhetorical question requires the answer I gave above because self-deceived people are always unaware of the lies they have grown to love and believe . They pride themselves as being sighted (one of their many lies) even though they are spiritually blind (Jn 9:41). Such people believe they have the power to see, yet Jesus taught that they cannot see. For them to actually see, they need to be born again, which is not a matter of man's "freewill" choice but rather a matter of Holy Spirit's choice. The new birth precedes understanding and faith.
3. GWH also ignores, downplays, diminishes or even dismisses the universal scope of this deception that reigns in all men's hearts w/o exception, in spite of the fact that the universality of deceitfulness CAN clearly be seen in the real world. Natural Revelation very clearly and plainly reveals this truth to all who have graciously been given eyes to see and ears to hear! And Natural Revelation always accurately reflects the objective, propositional truth claims of Special Revelation. Many moons ago when God revealed this truth to me, I labeled what I found to be a Universal Principle, hence I called it the Law of Distrust. So now...I'll reveal this commonly "known" law (although not by my label) but at the same time its implications are grossly misunderstood or even ignored by most. Now, I'll explain the law and since I wrote on this topic many moons ago, I will simply copy and paste what I wrote on a secular forum back on 2011. Just keep this one fact firmly in mind: This world, as we all know it, does NOT run on the honor system. And this, ironically, makes this ungodly, wicked, evil, depraved, dark world more spiritually savvy than many professing Christians! Here's the law:
Natural Revelation (reality as we know it) gives affirmation to the above doctrines with what I call the Universal Law of Distrust. This law states that all men are presumed to be untrustworthy unless they are known, or if unknown they can prove otherwise. Stated differently: all men unknown by others are presumed guilty of distrustfulness until they can prove otherwise. This is universally condemning commentary on mankind, is it not?
All governments, public and private institutions, businesses, etc, require that we prove the claims that we make to them before they honor them. You want a driver's license? Then you had better walk in with proof of identity. You want to fly on an airplane? You had better be prepared to prove who you are. You want to open up a bank account? Better have some I.D. on hand. Want to buy insurance? Better have all the necessary papers to prove who you are, what age you are, what values are legitimate, etc., etc.
And we can see this universal Law in play in another important way: We put locks on virtually everything of value we own. We lock our cars. We lock our homes. We padlock our sheds and barns. We buy safes with strong locks on them. We lock up our places of business. We even arm ourselves to protect our property. We buy expensive alarm systems for our homes, boats, cars, etc, etc. We install security cameras to monitor our property. We need to create strong passwords to protect against online intrustion of our privacy, etc. In short, we really don't trust our "neighbors" very well, do we?
We also see this how this Law has historically affected international relationships. Powerful nations, historically, have armed themselves to the teeth either because of their nefarious designs on other nations or because they wish to protect themselves from such nations they don't trust!
So, then, this Law as found in Natural Revelation gives affirmation to the teachings that are found in Special Revelation. Man truly does have a very serious moral/spiritual problem -- and it's universal in scope. This univesal distrust divides man: From himself, from his neighbors and ultimaely from God.
Because man is utterly and naturally untrustworthy accounts for why there is so little love in this world. It's very tough to love people we don't trust. The world at large ignores the Two Greatest Commandments and the "Golden Rule". This Law not only strongly affirms Jer 17:9 but other passages as well (Ps 116:11; Rom 3:4).
