Art Katz discusses the profound nature of sin, emphasizing that our sinful condition blinds us to our true state and necessitates an external revelation from God. He explains that sin is not merely a legal transgression but a deep affront to God's character and authority, encapsulated in His commandments. The crucifixion of Jesus serves as the ultimate revelation of sin's seriousness and God's judgment, highlighting the cost of our transgressions. Katz asserts that true understanding of ourselves and God comes from recognizing our total helplessness and the necessity of divine confrontation. Ultimately, he calls for a recognition of God's holiness and the gravity of sin as revealed through Christ's sacrifice.

John Gill expounds on 2 Peter 2:22, illustrating the profound truth of the proverb that likens apostates to dogs returning to their vomit and washed sows returning to mire. He emphasizes the filthy nature of sin and the irreclaimable state of those who turn away from the truth, highlighting that without a change in nature, they are doomed to revert to their former sinful ways. Gill draws parallels from Hebrew interpretations, reinforcing the idea that such individuals are trapped in their own defilement, unable to escape their sinful tendencies.

A.W. Tozer explores the nature of sin, emphasizing that for an act to be sinful, it must be a voluntary choice made with moral knowledge. He illustrates this with the example of Lucifer's rebellion against God, highlighting that sin is the conscious transgression of God's law. In contrast, Tozer points to Christ's submission in the Garden of Gethsemane, where He chose to align His will with the Father’s, demonstrating the conflict between human will and divine will. This distinction between the choices of Satan and Christ underscores the divide between righteousness and sinfulness. Tozer reassures that submitting to God's will does not negate our ability to choose, but rather fulfills our purpose as beings created in God's image.

Zac Poonen discusses the transformation from the old man to the new man in Christ, emphasizing that while the old man, representing our sinful nature, has been crucified, the new man desires to do God's will. He illustrates the difference between a disciple who may fall into sin and an unbeliever who willingly chooses it, comparing it to a cat and a pig in dirty water. Poonen stresses the importance of nurturing the new nature through the Word of God and prayer to resist sinful desires. He clarifies that falling into sin is different from practicing sin, providing comfort that believers have an Advocate in Jesus when they stumble.
