Charles Finney emphasizes that justification by faith does not nullify the moral law but rather establishes it, countering the belief that faith leads to moral laxity. He argues that true repentance and obedience stem from understanding the gospel, which presents God's love and grace rather than fear of punishment. Finney explains that the law alone cannot produce holiness; it is the gospel that transforms hearts and motivates true obedience through love. He warns against self-righteousness and highlights the necessity of recognizing salvation as a free gift, which leads to genuine love and concern for others. Ultimately, he asserts that the gospel is essential for breaking the chains of selfishness and leading sinners to true faith in Christ.

John Gill preaches on Romans 3:31, emphasizing that faith does not nullify the law but rather establishes it. He addresses concerns that the doctrine of grace leads to moral laxity, arguing instead that true faith results in obedience to God's law. Gill explains that justification comes through the righteousness of Christ, which fulfills the law's demands, and that believers are called to live in accordance with this law, empowered by grace. He asserts that the moral law remains relevant and is upheld by the gospel, which provides the means for true obedience. Ultimately, Gill encourages Christians to embrace the law as a guide for righteous living, demonstrating their faith through good works.

John Wesley emphasizes that faith does not nullify the law but rather establishes it, as articulated by St. Paul in Romans 3:31. He argues that while justification comes through faith alone, it does not exempt believers from the moral law, which remains essential for guiding righteous living. Wesley warns against the common misconception that faith diminishes the necessity of holiness, urging believers to maintain a diligent and obedient life in accordance with God's commands. He highlights the dangers of practical antinomianism, where individuals live as if grace allows for sin, and calls for a return to the conviction and zeal that characterized their earlier faith. Ultimately, Wesley encourages believers to examine their lives and ensure that their faith is accompanied by works that reflect their commitment to God's law.

Charles Finney explores Romans chapter 7, emphasizing the distinction between the experiences of a sinner under conviction and a true Christian. He critiques the common interpretation that this chapter reflects a Christian's struggle with sin, arguing instead that it describes the legal experience of a sinner who recognizes the law but remains unconverted. Finney stresses the importance of understanding this passage correctly, as misinterpretation can lead individuals to falsely believe they are saved when they are not. He concludes that true conversion results in a change of heart and a genuine desire to serve God, contrasting this with the mere desires of the unconverted.
