How does 2 Corinthians 5:21 illustrate the concept of substitutionary atonement?

The Verse at a Glance

“God made Him who knew no sin to be sin for us, so that in Him we might become the righteousness of God.” (2 Corinthians 5:21)


What Substitutionary Atonement Means

• One party takes the place of another.

• Guilt and penalty move from the sinner to the substitute.

• Righteous standing moves from the substitute to the sinner.

• Justice is satisfied, mercy is displayed.


Key Words in the Verse

• “knew no sin” – absolute sinlessness (Hebrews 4:15; 1 Peter 2:22).

• “to be sin” – treated as sin-bearer, taking our liability (Isaiah 53:6).

• “for us” – on our behalf, in our place (Galatians 3:13).

• “righteousness of God” – God’s own righteousness credited to us (Romans 3:21-22).


Old Testament Foundations

• Passover lamb: spotless, slain instead of the firstborn (Exodus 12:5-13).

• Day of Atonement: scapegoat bears Israel’s sins into the wilderness (Leviticus 16:20-22).

Isaiah 53:4-6: “He was pierced for our transgressions… the LORD has laid on Him the iniquity of us all.”


Christ as the Perfect Substitute

• Sinlessness qualified Him—no blemish to atone for Himself (1 John 3:5).

• Voluntary obedience—“I lay down My life… no one takes it from Me” (John 10:17-18).

• Once-for-all offering—“Christ was offered once to bear the sins of many” (Hebrews 9:28).


The Great Exchange Described

1. Our sin imputed to Christ.

– He bore the curse (Galatians 3:13).

2. His righteousness imputed to us.

– “Christ Jesus, who became for us… righteousness” (1 Corinthians 1:30).

3. Result: justified, reconciled, adopted.


Legal and Relational Dimensions

• Legal: satisfies divine justice—“God presented Him as an atoning sacrifice… to demonstrate His righteousness” (Romans 3:25-26).

• Relational: removes enmity—“we were reconciled to God through the death of His Son” (Romans 5:10).


Practical Implications

• Assurance—standing before God rests on Christ, not our performance.

• Gratitude—love generated by being fully forgiven (Luke 7:47).

• Holiness—clothed in righteousness, we pursue righteous living (Ephesians 2:10).

• Mission—message of reconciliation entrusted to us (2 Corinthians 5:19-20).
