# Why would forgiveness involve the cross?

Document: study/cross

Christ willingly bore the judgment our sins deserve.

Topic: jesus
Keywords: atonement, penal substitution, wrath, justice, foundation

## Starting answer

<!-- block: answer -->
God is holy and just, and our sin deserves judgment. In love, the Father sent the Son, who willingly offered himself as our substitute. Christ bore the penalty of sin and satisfied divine justice, reconciling his people to God. This is penal substitution, central to the Reformed account of the cross.

Basis: Isaiah 53:4-6; Romans 3:23-26; [Ligonier Ministries · Tabletalk devotional — Christ bearing the penalty of sin](https://learn.ligonier.org/devotionals/penal-substitution)

## Reasoning 1

<!-- block: reason-1 -->
Sin is guilt before God, not merely a feeling of shame or a lack of fulfilment.

Basis: Romans 3:19-23

## Reasoning 2

<!-- block: reason-2 -->
The sinless Christ bears our sins; his death is a willing gift.

Basis: 1 Peter 2:22-24; John 10:17-18

## Reasoning 3

<!-- block: reason-3 -->
Through Christ's blood God justifies sinners while remaining just.

Basis: Romans 3:24-26

## Conclusion

<!-- block: conclusion -->
Forgiveness rests on Christ's completed obedience and sacrifice, not on God overlooking evil or our paying him back.

Basis: Hebrews 10:10-14; [Westminster Assembly · OPC text — 8.5](https://opc.org/wcf.html)

## One saving work, several biblical descriptions

<!-- block: section-1 -->
Scripture also describes ransom, reconciliation and victory. These belong with Christ's bearing our guilt. We should not use one image to remove another part of what the Bible teaches.

Basis: Mark 10:45; 2 Corinthians 5:18-21; Colossians 2:13-15; [Ligonier Ministries · Tabletalk devotional — Biblical descriptions of the atonement](https://learn.ligonier.org/devotionals/penal-substitution)

## The Son gives himself

<!-- block: section-2 -->
The cross is not an unwilling stranger punished by a hostile deity. The incarnate Son freely lays down his life in obedience to the Father. God's love and God's justice meet in this saving work.

Basis: John 10:17-18; Romans 5:6-11

## Objection

Why can't God simply ignore the offence?

## Reply

<!-- block: reply -->
The gospel does not deny the seriousness of guilt. God condemns sin and grants mercy through Christ's sacrifice. The righteousness by which we stand before God is Christ's, received through faith.

Basis: Romans 3:25-26; 2 Corinthians 5:21; [John Calvin · Institutes III.11, Ligonier excerpt — Institutes III.11: forgiveness and imputed righteousness](https://learn.ligonier.org/articles/of-justification-by-faith)

## Scope and limits

<!-- block: limit -->
A courtroom or debt analogy is an aid to explanation, not a replacement for Scripture's account of the person and work of the mediator.

Basis: 1 Timothy 2:5-6; [Westminster Assembly · OPC text — 8.2–5](https://opc.org/wcf.html)

## Conversation starter · editorial application

<!-- block: conversation -->
What would forgiveness mean if God took both the evil of our sin and the cost of our rescue seriously?

Basis: Romans 5:8-11

## Sources and their limits

### Of Justification by Faith [calvin-justification]

John Calvin · Institutes III.11, Ligonier excerpt · Reformed exposition

[Read source](https://learn.ligonier.org/articles/of-justification-by-faith)

For forgiveness and Christ's righteousness received through faith alone, distinguished from the believer's renewal and works. Do not treat faith itself as a meritorious achievement.

### Penal Substitution [penal-substitution]

Ligonier Ministries · Tabletalk devotional · Reformed exposition

[Read source](https://learn.ligonier.org/devotionals/penal-substitution)

For Christ bearing the penalty of sin as substitute. Other biblical descriptions of the atonement complement this truth rather than displace it.

### Westminster Confession of Faith [wcf]

Westminster Assembly · OPC text · Reformed confession

[Read source](https://opc.org/wcf.html)

Our subordinate doctrinal standard for these guides. Citations specify chapter and paragraph. Scripture judges the confession itself (1.10); the confession does not replace Scripture.
