Charles Finney emphasizes the danger of self-deception among Christians who hear the Word but fail to act on it, distinguishing between two types of hypocrites: those who deceive others and those who deceive themselves. He argues that true saving faith requires not just intellectual agreement with the truth but a corresponding change in conduct, as faith must be active and produce good works. Finney warns that many professing Christians may enjoy sound doctrine without allowing it to influence their lives, leading to a false sense of piety. He calls for a Christianity that is rooted in obedience and practical application of the Word, urging believers to examine their lives for genuine faith. Ultimately, he stresses that true faith is evidenced by a transformed life that reflects obedience to God's commands.
