Secret faults are sins that we commit that we do not see or recognize as sins. We commit them not knowing we have committed sin. Nevertheless, we are still held accountable for our actions, and we will eventually pay the penalty. Ignorance of the law is no excuse. Presumptuous sins are willful sins, ones we do knowing that they are sin before we commit them. Such willful sins, depending on one's attitude, can be spiritually very dangerous.
The godly man is not only concerned about avoiding committing sins willfully, but also with extracting those hidden sins that are committed unknowingly. Because we so often allow our carnal natures to dominate us, we remain blind to many of our sins and character flaws until God reveals them to us through the Holy Spirit.

Comparing Ourselves Among Ourselves
Who among us really knows how much we sin? Who is really aware of how vile we are? Who even knows all the sins he has committed or are in the process of committing? Who knows how defiled we are by our flesh? How strong human nature is in us still—after who knows how many years of being in the church? So David says, "Cleanse me from the faults that I don't know about, others don't know about, that I've hidden from myself, that I didn't even know were sin."

David showed no hostility toward God, and he tried hard to change whenever he could see that he was wrong. However, he could not always see it. For instance, David stole Bathsheba, the wife of Uriah, and she became pregnant. After conniving and cheating in an attempt to avoid the consequences, David intentionally arranged for Uriah to be killed in battle.
Incredible as it may seem, David did not see how terribly wrong his sexual immorality in both his thoughts and actions was. He broke both the spirit and letter of the law. Not until the prophet Nathan brought him to his senses did spiritually blind David realize his sinful behavior.
Nevertheless, we cannot judge David too harshly, since our vision is likewise clouded regarding many of our problems. It is hard enough to recognize and admit the problems we can see, much less the ones we cannot. Rather than judge him, we can actually identify with David.

The Law's Purpose and Intent
Clearly, there is great similarity between Psalm 19 and Psalm 119, but there is also dissimilarity. The similarity, of course, is that the law of God is the focus for extolling all of the Word of God. The dissimilarity is that Psalm 19 is both more concise (after all, Psalm 119 is 176 verses) and more specific or more to the point. The author of this psalm is David. He uses law, statutes, precepts, commandments, fear, and ordinances as part of the means by which he intends to teach us something vital.
One might wonder why fear is included. It is because fear represents the specific attitude required to make the best use of God's law. Solomon writes in Proverbs 9:10, "The fear [a deep and abiding respect tinged with terror] of the LORD is the beginning of wisdom." In addition, remember that wisdom is right application of knowledge and understanding. If fear is not present, we will not even start to build towards faith, hope, and love. Godly fear gets us jump-started, gets us going to do what is right.
Psalm 19 is divided into three sections: The first section—beginning with "The heavens declare the glory of God" and concluding in verse 6—concerns the revelation of the Creator God in His creation. The second part, beginning with verse 7 and extending through verse 11, is the revelation of the Covenant God in His Word, most specifically in His law. The third part comprises the last few verses, and it contains the response of the man of faith to the first two sections.
In "the heavens declare the glory of God," the word "God" is not Elohim but the singular El. In verse 7, LORD is Yahweh. Thus, the same Being is identified as El and Yahweh. Through this psalm, David is saying that, though the creationreveals the majesty and the power—the implication of the name "El"—of the One who created, the law of God reveals in a much clearer, more comprehensive way the specifics of the nature, character, and purpose of that Being—as suggested by the name "Yahweh." God's law is, therefore, of far more practical help to the created, us.
Thus, he makes a comparison. He says, "Here is the creation. It is great and good. However, it does not even begin to teach you as the law of God does." The specifics that we need about how to live are in the law of God. Both are needed, but the revelation of the law takes one far beyond the nature of the creation.
