Christ bore our sins though He knew no sin

Psalm 18 presents a striking paradox. David declares his uprightness before God—"I was also upright before him, and I kept myself from mine iniquity." Yet this same psalm, when read messianically through the lens of Scripture, applies to Christ Himself. In Psalm 40, the Psalmist confesses, "innumerable evils have compassed me about; mine iniquities have taken hold upon me." Our Lord identified Himself with these very words.

How can the sinless Christ claim such guilt? The resolution lies in Christianity's peculiar glory: substitutionary atonement. As Isaiah declares, "He who knew no sin was made sin." The text employs two Latin distinctions that illuminate this mystery. In the sense of culpa—blameworthiness—Christ had no sin whatsoever. His character remained spotless, His obedience perfect. Yet in the sense of reatus—legal liability to penal consequences—never has anyone borne such weight. "On his righteous servant, Jehovah made to fall the iniquities of us all."

Those innumerable evils that compassed Him were not His own transgressions but ours, divinely transferred to His account. By appointment of the Father, He assumed our liabilities as surely as a guarantor assumes a debtor's obligation. This is why He could cry out in our stead, bearing the full judicial weight of human sin while maintaining absolute moral perfection. He bore the sins of many—innocent yet guilty by imputation, holy yet made answerable for our transgression.
