Excusing sin emerges as the second major deterrent to overcoming, following directly from self-deception. Once a person begins to strip away the self-deception that hides his faults, he dislikes what he sees when comparing himself to the perfect Word of God, and so he begins making excuses, attempting to portray his wrongdoing as good, or at least less serious than it appears. This self-justification leads a person to defend either his behavior or his unwillingness to change it. This tendency to excuse sin is as old as humanity itself. From Adam and Eve onward, people have tried to hide their failings from God, from others, and even from themselves, since admitting wrongdoing is one of the hardest things for a human being to do. Scripture recognizes this pattern clearly, noting how people invent absurd justifications, such as blaming weather or wild beasts, for failing to fulfill responsibilities. Solomon warns that such self-justification can be destructive, and that because judgment for evil is not always immediate, the human heart becomes fully set on doing wrong, since it perceives no consequence. This pattern of excuse-making appears in common rationalizations for laziness or unproductiveness, such as claiming a task was too hard, blaming lack of time, or insisting one simply did not know how. Christ does not receive such excuses favorably, as seen in the Parables of the Minas and the Talents, where the servant who buried what was entrusted to him is called wicked and lazy. Judgment will be according to works and fruits, not according to intentions or excuses offered afterward. The habit of excusing sin is also transmitted to children when parents excuse their own sins or those of their offspring, blaming circumstances, moods, or bad influences rather than requiring accountability. This same pattern appears in society's tendency to excuse serious wrongdoing through claims such as temporary insanity, which may succeed in human courts but not before God. Another common excuse is the appeal to universal sinfulness, admitting to being "only human" or "a sinner like everyone else" without acknowledging specific faults. Though it is true that all have sinned, God is concerned with each person's individual repentance, meaning a complete turning away from sin, not with excuses. Ultimately, self-justification gains nothing, since the penalty for sin remains death, and only the sacrificial death of Jesus Christ can truly justify a person before God, provided one repents rather than continues to excuse wrongdoing. David serves as a powerful example of moving beyond excuse-making. After using various self-justifications for his adultery and murder, he was confronted by Nathan the prophet, stripped of his self-deception and self-justification, and responded with genuine repentance, asking God to cleanse and purge him rather than defending himself further. His example demonstrates true repentance and overcoming, standing in contrast to the excuse-making that otherwise prevents growth toward the Kingdom of God.

The material presents excusing sin as the opposite extreme from irritant idolatry, in which an offensive person or circumstance occupies so much attention that God is displaced from the center of one's view. Rather than allowing irritation over sin to become an idol, one must avoid the contrary error of winking at transgression or adopting moral relativism that treats all behavior as acceptable. Such tolerance is rejected because it ultimately excuses one's own conduct as readily as anyone else's. The proper response lies between these poles: sin must remain genuinely upsetting, especially one's own, yet God must stay squarely in focus so that the reaction does not eclipse His sovereignty or timing. This balance appears in the account of those marked for preservation in Jerusalem. They sigh and cry over the abominations around them without either ignoring the offenses or attempting to correct them through their own initiative. Their grief over idolatry and other evils remains clear-sighted because it does not obscure their vision of God; instead they wait for Him to act. The same principle applies within the spiritual family, where God's sovereignty and the headship of Jesus Christ require that any necessary action, such as following the process in Matthew 18 or addressing blatant unrepentant conduct, proceed from humility and a recognition that the Father and the Son alone see all circumstances and move according to Their will. Human judgment, however accurate in principle, must not supplant that divine perspective, lest the believer either idolize the irritant or excuse the sin.
