Alexander McLeod’s “Christ a Surety for Sinners” explains Christ’s role as the representative and substitute of his people in the covenant of grace. McLeod argues that humanity’s sin created a debt toward God that Christ fully satisfied through his obedience, sufferings, and death. He emphasizes that Christ’s atonement truly secures salvation for those given to him by the Father, rather than merely making salvation possible. The article concludes by calling sinners to rest entirely on the sufficiency of Christ’s work and to marvel at the grace and glory revealed in redemption.
