Gene Higgins examines the central importance of the cross of Christ from 1 Peter 3:18, highlighting its necessity, effectiveness, and power in the gospel message. He addresses various criticisms and objections to the doctrine of atonement—including historical rejections by the Nazi regime, modern secular dismissals, and liberal theological viewpoints such as the moral influence theory. Higgins emphasizes the unique character of Christ's death as a voluntary, substitutionary sacrifice by the sinless for the unjust, providing a payment that satisfies divine righteousness and secures eternal redemption for believers.
