John Nelson Darby addresses the critical issue of doctrinal purity in his sermon 'Remarks on Failure,' emphasizing the severe consequences of corrupting the gospel. He highlights the Apostle Paul's strong rebuke of those who distort the truth, warning that any deviation from the grace of Christ leads to spiritual ruin. Darby contrasts the laxity of contemporary attitudes towards doctrine with the seriousness of maintaining the integrity of the gospel, asserting that true faith must prioritize God's truth over human reasoning. He calls for a return to the foundational truths of grace and warns against the dangers of legalism and worldly influences within the church. Ultimately, he urges believers to uphold the gospel's purity and to recognize the vital connection between doctrine and moral conduct.

Charles Finney addresses the distinction between true and false religion, emphasizing that many people practice a form of religion that is merely a yoke of bondage rather than a source of genuine liberty. He explains that true liberty is found in a relationship with Christ, characterized by love and joy, rather than legalistic observance. Finney warns against the Judaizers who sought to combine legalism with Christianity, asserting that true faith is based solely on justification by faith. He encourages believers to examine their hearts and ensure that their faith is not a burdensome obligation but a joyful expression of love for God. Ultimately, he calls for a return to the freedom that comes from Christ, urging listeners to reject the chains of false religion.
