2 Corinthians 5:21

Greek Key Terms

Context: Paul's made-sin formula supplies the doctrinal content the serpent's venomless-bronze paradox pictures — Paul does not cite Numbers 21; the correspondence is drawn under John 3:14's dominical warrant: "God made Him who knew no sin to be sin on our behalf, so that in Him we might become the righteousness of God." Just as the bronze serpent bore the likeness of the serpent but contained no venom, Christ was made "to be sin on our behalf" though He "knew no sin." He bore the form of the curse without containing the poison of guilt. This is the great exchange: our sin imputed to Him, His righteousness imputed to us.

Connections

Christological Connection: Second Corinthians 5:21 supplies the doctrinal content of the bronze serpent typology that Jesus established in John 3:14-15 — Paul does not cite Numbers 21; the correspondence is drawn under that dominical warrant. The bronze serpent bore the image of the deadly thing (serpent—the creature that brought the curse in Genesis 3) while containing no venom. It was bronze, not flesh; an image, not the reality; bearing the form without the substance. Paul explains the antitype: Christ was made "to be sin on our behalf" (bearing sin's full reality and judgment) though He "knew no sin" (containing no personal guilt or moral corruption). The parallel is exact: as the bronze serpent bore death's likeness without death's poison, Christ bore sin's penalty without sin's guilt. The phrase "to be sin on our behalf" is theologically loaded. It can mean (1) Made a sin offering—connecting to Leviticus 4 where the sin offering (ḥaṭṭāʾt, LXX hamartia) bore the sinner's guilt symbolically; (2) Identified with sin—Christ took sin's full weight and judgment upon Himself; (3) Became sin's substitute—what should have fallen on us fell on Him. Isaiah prophesied that "the LORD has laid upon Him the iniquity of us all" (Isaiah 53:6); Paul declares that God "made Him... to be sin on our behalf." The result is the great exchange: "so that in Him we might become the righteousness of God." As completely as Christ was identified with our sin, we are identified with His righteousness. As the Israelites looked to the bronze serpent (bearing judgment's image) for physical healing, believers look to Christ (bearing sin's reality) for spiritual salvation. Galatians 3:13 parallels this: "Christ redeemed us from the curse of the law by becoming a curse for us"—the same principle of substitutionary identification. First Peter 2:24 adds: "He Himself bore our sins in His body on the tree"—connecting the cross ("tree") to curse-bearing. The bronze serpent was lifted up so dying Israelites could look and live; Christ was lifted up on the cross, made "to be sin on our behalf," so dying sinners could believe and be made righteous. The typology's fulfillment surpasses the type: the bronze serpent granted temporary physical life; Christ grants eternal spiritual life. The bronze serpent bore sin's image; Christ bore sin's substance. What the bronze serpent foreshadowed, 2 Corinthians 5:21 explains: the sinless one made sin, that sinners might be made righteous.

Connection Method(s): Typology (Providential Type — Progressive Clarification — Backward-Looking) — Paul's made-sin formula supplies the doctrinal content the serpent's venomless-bronze paradox pictures (Paul does not cite Numbers 21; the correspondence is drawn under John 3:14's dominical warrant): as the serpent bore sin's image without venom, Christ was made "to be sin on our behalf" though He "knew no sin," accomplishing the great exchange of imputed guilt and imputed righteousness.
