Horatius Bonar emphasizes the gravity of human sin and the certainty of God's remembrance of it, as illustrated in Hosea 7:2. He explains that sin is not merely a mistake or misfortune but a profound guilt that demands divine justice. Bonar warns against the human tendency to downplay sin and forget its consequences, while reminding us that God's memory is infallible and eternal. However, he also offers hope through the New Covenant, where the blood of Christ allows God to forget our sins, providing a righteous oblivion for those who accept this gift. Ultimately, Bonar calls for a serious reflection on sin and the assurance of God's forgiveness through faith in Christ.

Gill highlights the importance of acknowledging our sinful nature and the need for divine healing through Christ, the ultimate physician. He calls believers to humbly confess their sins and rely on God's grace for restoration and pardon.
