Charles Finney emphasizes the distinction between legal and gospel service to God, arguing that true service arises from a heart transformed by holiness and benevolence. He explains that legal service is motivated by fear or obligation, while gospel service is a joyful expression of love for God and others. Finney asserts that acceptable service to God requires a radical change of heart, aligning one's motives with God's desire for universal good. He warns that without this transformation, individuals cannot truly serve the Lord, as He is a holy God. Ultimately, Finney calls for a deep, heartfelt commitment to the service of God that brings joy and satisfaction.

Charles Finney addresses the issue of false professors in his sermon 'False Professors,' emphasizing that many individuals claim to fear God while actually serving their own idols and selfish interests. He illustrates how people may perform religious duties out of a fear of judgment rather than genuine devotion, and he challenges listeners to examine their true motivations and commitments. Finney categorizes various groups of people who, despite their outward religious practices, prioritize personal gain and comfort over the service of God and the salvation of souls. He calls for a radical re-evaluation of what it means to serve God, urging believers to make their lives a true reflection of their faith. Ultimately, he warns that mere profession without true service is hypocrisy.

Charles Finney addresses the issue of idolatry and the fear of God, emphasizing that many people fear the Lord while still serving their own gods, driven by selfish motives rather than true devotion. He explains that there are two types of fear: a reverent fear rooted in love and a slavish fear based on dread of punishment, which leads to a superficial worship that does not involve true service to God. Finney challenges the notion of 'Sunday Christians' who compartmentalize their faith, serving God only on Sundays while pursuing their own interests throughout the week. He calls for a radical commitment to serving God in all aspects of life, urging believers to renounce selfishness and prioritize the advancement of God's Kingdom. Ultimately, he warns that true Christianity requires a complete surrender of oneself and one's possessions to God, rather than a mere performance of religious duties.
