Charles Finney addresses the dangers of philosophical preaching that prioritizes human understanding over faith in God's revelation. He warns that such an approach can lead to pride and a lack of true faith, as it encourages believers to rely on their own reasoning rather than the authority of Scripture. Finney emphasizes the importance of presenting the gospel as facts to be believed on God's testimony, rather than requiring philosophical explanations that may undermine faith. He advocates for a balanced approach that nurtures faith while also allowing for understanding, cautioning against the pitfalls of intellectualism in spiritual matters. Ultimately, he calls for a return to humility and reliance on God's word to foster genuine spiritual growth.
