"The apostle says 'our,' 'our sins;' not his own sin, not the sins of unbelievers. Purification is not for, and cannot profit, him who does not believe. Nor did Christ effect the cleansing by our free-will, our reason or power, our works, our contrition or repentance, these all being worthless in the sight of God; he effects it by himself. And how? By taking our sins upon himself on the holy cross, as Isaiah 53:6 tells us."
