Charles Finney addresses the issue of tobacco use among Christians, emphasizing that example is a powerful teacher, often leading children to adopt habits contrary to their parents' teachings. He argues that using tobacco cannot be justified as it does not glorify God and is a form of self-indulgence that can dominate one's life, making it a sin. Finney challenges the notion that tobacco is beneficial, asserting that any perceived benefits are outweighed by the harm it causes to both the individual and society. He encourages Christians to deny themselves for the sake of others and to consider the moral implications of their actions. Ultimately, he calls for a commitment to live in a way that promotes the glory of God and the well-being of others.
