Charles Finney addresses the prevalent infidelity among young men, emphasizing that many doubt the inspiration of the Scriptures not from honest study but from a lack of understanding their own moral nature. He argues that our conscience and moral intuitions reveal the existence of God and the moral law, which the Bible assumes as a foundation for its teachings. Finney illustrates this through a conversation with a skeptic, demonstrating how acknowledging one's moral failures leads to the recognition of the need for salvation through the Gospel. He concludes that rejecting the Bible is absurd when it aligns with our innate moral convictions and that the Gospel provides the necessary hope for redemption. Ultimately, he urges listeners to embrace the truth of the Gospel as the solution to their spiritual needs.

Despite these traits, Sparks highlights that Thomas was chosen by the Lord, indicating that even those with such dispositions have a vital role in the Church when they are redeemed. The resurrection represents a crisis for Thomas, calling for a deeper surrender and a shift from a reliance on human reasoning to a faith that embraces the spiritual. Ultimately, Thomas's journey illustrates the need for believers to be adaptable and open to the transformative power of the resurrection.
