The Noetic Effects of Sin by Jack Kettler
“Shew me thy ways, O LORD; teach me thy paths.” (Psalm 25:4)
In this study, we will look at the biblical teaching regarding noetic effects of sin. What does this mean? What are the implications for counseling and apologetics?
As in previous studies, we will look at definitions, scriptures, lexical evidence, commentary evidence and confessional support for the purpose to glorify God in how we live. May God be glorified always!
Noetic effects of sin:
“The negative effect of sin on the minds and thinking of humankind, causing the reasoning ability of fallen humanity to be corrupted, especially degrading the understanding of spiritual things; also called the noetic effects of the fall.” *
Noetic effect of sin:
“The noetic effect of sin is the effect upon the mind. The Greek word for "mind" is "nous." Therefore, ‘noetic’ deals with the mind, or the rational aspect of the person. This effect means that our reasoning abilities are no longer pure and proper all the time. But, it does not mean we will always reason improperly. We can think rationally, use mathematics, make proper judgments, etc. But, as is obvious, there are many false religions in the world that are believed and defended intellectually. So, the noetic effect of sin upon the mind most assuredly manifests itself in the belief of false gods, false Christ, false gospels, etc.” **
“Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.” (Romans 1:21)
“Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart.” (Ephesians 4:18)
From Calvin's Commentary on Romans 1:18-23:
18. For  revealed, etc. He reasons now by stating things of a contrary nature, and proves that there is no righteousness except what is conferred, or comes through the gospel; for he shows that without this all men are condemned: by it alone there is salvation to be found. And he brings, as the first proof of condemnation, the fact, -- that though the structure of the world, and the most beautiful arrangement of the elements, ought to have induced man to glorify God, yet no one discharged his proper duty: it hence appears that all were guilty of sacrilege, and of wicked and abominable ingratitude.
To some it seems that this is a main subject, and that Paul forms his discourse for the purpose of enforcing repentance; but I think that the discussion of the subject begins here, and that the principal point is stated in a former proposition; for Paul's object was to teach us where salvation is to be found. He has already declared that we cannot obtain it except through the gospel: but as the flesh will not willingly humble itself so far as to assign the praise of salvation to the grace of God alone, Paul shows that the whole world is deserving of eternal death. It hence follows, that life is to be recovered in some other way, since we are all lost in ourselves. But the words, being well considered, will help us much to understand the meaning of the passage.
Some make a difference between impiety and unrighteousness, and think, that by the former word is meant the profanation of God's worship, and by the latter, injustice towards men; but as the Apostle immediately refers this unrighteousness to the neglect of true religion, we shall explain both as referring to the same thing.  And then, all the impiety of men is to be taken, by a figure in language, as meaning "the impiety of all men," or, the impiety of which all men are guilty. But by these two words one thing is designated, and that is, ingratitude towards God; for we thereby offend in two ways: it is said to be asebeia, impiety, as it is a dishonoring of God; it is adikia, unrighteousness, because man, by transferring to himself what belongs to God, unjustly deprives God of his glory. The word wrath, according to the usage of Scripture, speaking after the manner of men, means the vengeance of God; for God, in punishing, has, according to our notion, the appearance of one in wrath. It imports, therefore, no such emotion in God, but only has a reference to the perception and feeling of the sinner who is punished. Then he says that it is revealed from heaven; though the expression, from heaven, is taken by some in the sense of an adjective, as though he had said “the wrath of the celestial God;” yet I think it more emphatical, when taken as having this import, “Wheresoever a man may look around him, he will find no salvation; for the wrath of God is poured out on the whole world, to the full extent of heaven.”
The truth of God means, the true knowledge of God; and to hold in that, is to suppress or to obscure it: hence they are charged as guilty of robbery. -- What we render unjustly, is given literally by Paul, in unrighteousness, which means the same thing in Hebrew: but we have regard to perspicuity. 
19. Inasmuch as what may be known of God, etc. He thus designates what it behoves us to know of God; and he means all that appertains to the setting forth of the glory of the Lord, or, which is the same thing, whatever ought to move and excite us to glorify God. And by this expression he intimates, that God in his greatness can by no means be fully comprehended by us, and that there are certain limits within which men ought to confine themselves, inasmuch as God accommodates to our small capacities what he testifies of himself. Insane then are all they who seek to know of themselves what God is: for the Spirit, the teacher of perfect wisdom, does not in vain invite our attention to what may be known, to gnoston; and by what means this is known, he immediately explains. And he said, in them rather than to them, for the sake of greater emphasis: for though the Apostle adopts everywhere Hebrew phrases, and v, beth, is often redundant in that language, yet he seems here to have intended to indicate a manifestation, by which they might be so closely pressed, that they could not evade; for every one of us undoubtedly finds it to be engraven on his own heart,  By saying, that God has made it manifest, he means, that man was created to be a spectator of this formed world, and that eyes were given him, that he might, by looking on so beautiful a picture, be led up to the Author himself.
20. Since his invisible things,  etc. God is in himself invisible; but as his majesty shines forth in his works and in his creatures everywhere, men ought in these to acknowledge him, for they clearly set forth their Maker: and for this reason the Apostle in his Epistle to the Hebrews says, that this world is a mirror, or the representation of invisible things. He does not mention all the particulars which may be thought to belong to God; but he states, that we can arrive at the knowledge of his eternal power and divinity;  for he who is the framer of all things, must necessarily be without beginning and from himself. When we arrive at this point, the divinity becomes known to us, which cannot exist except accompanied with all the attributes of a God, since they are all included under that idea.
So that they are inexcusable. It hence clearly appears what the consequence is of having this evidence -- that men cannot allege anything before God's tribunal for the purpose of showing that they are not justly condemned. Yet let this difference be remembered, that the manifestation of God, by which he makes his glory known in his creation, is, with regard to the light itself, sufficiently clear; but that on account of our blindness, it is not found to be sufficient. We are not however so blind, that we can plead our ignorance as an excuse for our perverseness. We conceive that there is a Deity; and then we conclude, that whoever he may be, he ought to be worshipped: but our reason here fails, because it cannot ascertain who or what sort of being God is. Hence the Apostle in Hebrews 11:3, ascribes to faith the light by which man can gain real knowledge from the work of creation, and not without reason; for we are prevented by our blindness, so that we reach not to the end in view; we yet see so far, that we cannot pretend any excuse. Both these things are strikingly set forth by Paul in Acts 14:16-17, when he says, that the Lord in past times left the nations in their ignorance, and yet that he left them not without witness (amarturon,) since he gave them rain and fertility from heaven. But this knowledge of God, which avails only to take away excuse, differs greatly from that which brings salvation, which Christ mentions in John 17:3, and in which we are to glory, as Jeremiah teaches us, Jeremiah 9:24
21. For when they knew God, etc. He plainly testifies here, that God has presented to the minds of all the means of knowing him, having so manifested himself by his works, that they must necessarily see what of themselves they seek not to know -- that there is some God; for the world does not by chance exist, nor could it have proceeded from itself. But we must ever bear in mind the degree of knowledge in which they continued; and this appears from what follows.
They glorified him not as God. No idea can be formed of God without including his eternity, power, wisdom, goodness, truth, righteousness, and mercy. His eternity appears evident, because he is the maker of all things -- his power, because he holds all things in his hand and continues their existence -- his wisdom, because he has arranged things in such an exquisite order -- his goodness, for there is no other cause than himself, why he created all things, and no other reason, why he should be induced to preserve them -- his justice, because in his government he punishes the guilty and defends the innocent -- his mercy, because he bears with so much forbearance the perversity of men -- and his truth, because he is unchangeable. He then who has a right notion of God ought to give him the praise due to his eternity, wisdom, goodness, and justice. Since men have not recognized these attributes in God, but have dreamt of him as though he were an empty phantom, they are justly said to have impiously robbed him of his own glory. Nor is it without reason that he adds, that they were not thankful,  for there is no one who is not indebted to him for numberless benefits: yea, even on this account alone, because he has been pleased to reveal himself to us, he has abundantly made us indebted to him. But they became vain,  etc.; that is, having forsaken the truth of God, they turned to the vanity of their own reason, all the acuteness of which is fading and passes away like vapor. And thus their foolish mind, being involved in darkness, could understand nothing aright but was carried away headlong, in various ways, into errors and delusions. Their unrighteousness was this -- they quickly choked by their own depravity the seed of right knowledge, before it grew up to ripeness.
22. While they were thinking, etc. It is commonly inferred from this passage, that Paul alludes here to those philosophers, who assumed to themselves in a peculiar manner the reputation of wisdom; and it is thought that the design of his discourse is to show, that when the superiority of the great is brought down to nothing, the common people would have no reason to suppose that they had anything worthy of being commended: but they seem to me to have been guided by too slender a reason; for it was not peculiar to the philosophers to suppose themselves wise in the knowledge of God, but it was equally common to all nations, and to all ranks of men. There were indeed none who sought not to form some ideas of the majesty of God, and to make him such a God as they could conceive him to be according to their own reason. This presumption I hold is not learned in the schools, but is innate, and comes with us, so to speak, from the womb. It is indeed evident, that it is an evil which has prevailed in all ages -- that men have allowed themselves every liberty in coining superstitions. The arrogance then which is condemned here is this -- that men sought to be of themselves wise, and to draw God down to a level with their own low condition, when they ought humbly to have given him his own glory. For Paul holds this principle, that none, except through their own fault, are unacquainted with the worship due to God; as though he said, “As they have proudly exalted themselves, they have become infatuated through the righteous judgment of God.” There is an obvious reason, which contravenes the interpretation which I reject; for the error of forming an image of God did not originate with the philosophers; but they, by their consent, approved of it as received from others. 
23. And changed, etc. Having feigned such a God as they could comprehend according to their carnal reason, they were very far from acknowledging the true God: but devised a fictitious and a new god, or rather a phantom. And what he says is, that they changed the glory of God; for as though one substituted a strange child, so they departed from the true God. Nor are they to be excused for this pretense, that they believe that God dwells in heaven, and that they count not the wood to be God, but his image; for it is a high indignity to God, to form so gross an idea of his majesty as to dare to make an image of him. But from the wickedness of such a presumption none were exempt, neither priests, nor statesmen, nor philosophers, of whom the most sound-minded, even Plato himself, sought to find out some likeness of God.
The madness then here noticed, is, that all attempted to make for themselves an image of God; which was a certain proof that their notions of God were gross and absurd. And, first, they befouled the majesty of God by forming him in the likeness of a corruptible man: for I prefer this rendering to that of mortal man, which is adopted by Erasmus; for Paul sets not the immortality of God in opposition to the mortality of man, but that glory, which is subject to no defects, to the most wretched condition of man. And then, being not satisfied with so great a crime, they descended even to beasts and to those of the most filthy kind; by which their stupidity appeared still more evident. You may see an account of these abominations in Lactantius, in Eusebius, and in Augustine in his book on the city of God. (1)
Calvin on the Sensus Divinitatis or the sense of divinity:
“That there exists in the human mind and indeed by natural instinct, some sense of Deity [sensus divinitatis]. This we take to be beyond dispute, since God himself, to prevent any man from pretending ignorance, has endued all men with some idea of his Godhead.” (2)
Closely related to the sensus divinitatis is the Imago Dei or the image of God:
In Christian theology, the Imago Dei, Latin for the image of God refers to the stamp of God placed upon humankind. A man is an image bearer of God. In the fall, this image is marred.
As Calvin has explained in his comments on Romans 1:18-23 and on the sensus dvinitatis, fallen humankind even though fallen in sin, have an awareness of God’s presence or knowledge of Him. Sinful men suppress this knowledge. A fallen man is not neutral. Understanding this about fallen men has implications for biblical apologetics and biblical counseling. This innate knowledge in the fallen man becomes a point contact as the believer approaches the non-believer.
In the area of counseling, this is approach is nouthetic counseling or biblical counseling. Nouthetic counseling breaks with non-Christian phycology, and Christian non-believer influenced phycology.
In the area of apologetics, this approach is presuppositional apologetics. Presuppositional apologetics presents the Christian religion from the Bible and defends it against opposition by means of exposing the logical fallacies or specifically the reductio ad absurdum of non-Christian worldviews, and consequently, establishes the biblical worldview as the only worldview that can account for a consistent sense of reality.
Presuppositional apologetics exclusively argues for the biblical God, and not just the existence of some kind of god or a simple theism devoid of any content. An example of theism without content would be Aristotle’s prime mover. Aristotle’s prime mover is nothing more than a philosophical construct. In contrast, the God of Holy Scripture reveals His characteristics in His written Word.
Confessional support from the Canons of Dordt the Noetic Effects of Sin:
The Third and Fourth Main Points of Doctrine
The Effect of the Fall on Human Nature
Man was originally created in the image of God and was furnished in his mind with a true and salutary knowledge of his Creator and things spiritual, in his will and heart with righteousness, and in all his emotions with purity; indeed, the whole man was holy. However, rebelling against God at the devil’s instigation and by his own free will, he deprived himself of these outstanding gifts. Rather, in their place he brought upon himself blindness, terrible darkness, futility, and distortion of judgment in his mind; perversity, defiance, and hardness in his heart and will; and finally impurity in all his emotions.
The Spread of Corruption
Man brought forth children of the same nature as himself after the fall. That is to say, being corrupt he brought forth corrupt children. The corruption spread, by God’s just judgment, from Adam to all his descendants - except for Christ alone - not by way of imitation (as in former times the Pelagians would have it) but by way of the propagation of his perverted nature.
The Inadequacy of the Light of Nature
There is, to be sure, a certain light of nature remaining in man after the fall, by virtue of which he retains some notions about God, natural things, and the difference between what is moral and immoral, and demonstrates a certain eagerness for virtue and for good outward behavior. But this light of nature is far from enabling man to come to a saving knowledge of God and conversion to him - so far, in fact, that man does not use it rightly even in matters of nature and society. Instead, in various ways he completely distorts this light, whatever its precise character, and suppresses it in unrighteousness. In doing so, he renders himself without excuse before God.
As noted, a man suppresses this knowledge of God, yet it remains the best point of contact for evangelism and discipleship by appealing to this sensus divinitatis using biblical theology that replicates this approach along with the converting power of the Holy Spirit.
