Charles Finney addresses the complexities of moral obligation in relation to ignorance and natural ability, challenging the notion that the law of God requires more from individuals than they are capable of fulfilling given their circumstances. He argues that ignorance, often a result of moral failure, constitutes a natural inability to obey God's commands, and that the law's demands are aligned with one's current capacity. Finney emphasizes that true sanctification can only occur as ignorance is dispelled through the truth and the Spirit of God, and he critiques the inconsistency of those who claim that God requires perfect obedience while denying the impact of human depravity on moral agency. He calls for a deeper understanding of the relationship between knowledge, moral obligation, and the law of God, urging his brethren to reconsider their positions on these critical theological issues.
