Why does Jesus judge actions in Matt 25?
If good works don’t save, why does Jesus say people will be judged by their actions in Matthew 25:31-46?

I. Context and Overview

Matthew 25:31–46 presents a vivid scene of the Son of Man separating people “as a shepherd separates the sheep from the goats.” Upon a plain reading, the passage appears to indicate that one’s eternal destiny rests entirely on how they treated the “least of these” (Matthew 25:40). However, the wider teaching of Scripture affirms that good works, while indispensable as fruit and evidence of genuine faith, are not the basis for salvation (Ephesians 2:8–9). This entry aims to reconcile these concepts, exploring the purpose for our works in light of God’s judgment and explaining how both grace and divine justice are coherent in the overarching message of Scripture.


II. The Biblical Foundation of Salvation by Faith

Salvation in the Bible is consistently presented as a gift of God’s grace received through faith.

1. Ephesians 2:8–9: “For it is by grace you have been saved through faith, and this not from yourselves; it is the gift of God, not by works, so that no one can boast.”

2. Romans 3:28: “For we maintain that a man is justified by faith apart from works of the law.”

These verses demonstrate that all people, regardless of their background, are justified before God because of faith in Christ’s atoning work, not by personal achievement. This scriptural principle guards against the notion that human merit alone can save an individual.


III. The Role of Works in the Judgment Scene

Despite the unequivocal teaching on salvation by faith, Scripture also emphasizes works as having a clear role in God’s judgment. In Matthew 25:31–46, recipients of eternal inheritance are commended not for their faith in isolation but for benevolent actions—feeding the hungry, welcoming strangers, clothing the needy, visiting the sick and imprisoned.

1. Evidence of Genuine Faith

Throughout the Gospels, Jesus teaches that those who truly believe will bear fruit worthy of repentance (Matthew 3:8). This is a consistent message with James 2:17: “So too, faith by itself, if it does not result in action, is dead.” Works are a natural overflow and outworking of an authentic faith. The biblical text never elevates human works as the ultimate cause of salvation; rather, works give evidence that genuine salvation has taken root.

2. Demonstration of Heart Transformation

When people stand before God, the actions by which they are judged reveal whether they have truly been changed by God’s grace. Jesus says, “a tree is recognized by its fruit” (Matthew 12:33). Hence, righteous deeds become external markers reflecting the condition of the heart. An unchanged heart produces selfishness and uncaring attitudes, while a heart regenerated by God’s Spirit produces compassion and selflessness.

3. Legal vs. Relational Aspect

The “sheep and goats” narrative also incorporates a relational dimension: those genuinely in relationship with Christ naturally respond with acts of love both toward God and toward others. As Jesus taught, “Whatever you did for one of the least of these brothers of Mine, you did for Me” (Matthew 25:40). This indicates the personal identification that Jesus has with those in need. It shows that acts of mercy done for others (especially fellow believers or those in dire need) are received by Christ as acts of devotion to Himself.


IV. Scriptural Examples of Faith and Action Together

1. Abraham’s Obedience

James 2:21–22 highlights Abraham’s demonstration of faith through actions: “Was not our father Abraham justified by what he did when he offered his son Isaac on the altar? You see that his faith was working with his actions, and his faith was perfected by what he did.” Although Abraham was counted righteous by faith (Genesis 15:6), it was a faith that tangibly altered his behavior.

2. Rahab’s Helpfulness

James 2:25 points to Rahab’s faith, manifested by “welcoming the spies and sending them off by a different route.” Her actions indicated that she trusted in the God of Israel. It was not the act itself that saved her; rather, the act was proof she believed in the God who saves.

In each case, the action is the fruit of faith, confirming that genuine faith will bring about visible, tangible change.


V. Judgment According to Works in Light of the Entire Biblical Message

1. Consistency with the Prophets

The Old Testament prophets frequently emphasize that God calls His people to practice justice, mercy, and humility (Micah 6:8). These acts are meant to reflect a heart truly devoted to God. Judgment fell upon Israel when they abstained from righteous living and turned to idolatry, ignoring the poor and oppressed (e.g., Isaiah 58:6–7). In effect, though their religious rituals were many, their hearts’ actual condition was revealed through neglect of charity and justice.

2. Paul’s Teaching on the Judgment Seat

In 2 Corinthians 5:10, Paul writes, “For we must all appear before the judgment seat of Christ, that each one may receive his due for the things done in the body, whether good or bad.” This point parallels Jesus’ words in Matthew 25:31–46. However, Paul never contradicts the principle that salvation is through faith alone. Instead, his teaching on accountability underscores that the authenticity of one’s faith will be measured through the life it produces.

3. John’s Reflection on Works

The book of Revelation also depicts a scenario of final judgment where books are opened to reveal human works (Revelation 20:12–13). Yet this is fully consistent with the gospel’s teaching: works function as confirmatory evidence of a person’s allegiance to Christ. The biblical record, therefore, upholds a final assessment in which those who have been redeemed by Christ will showcase their redeemed nature by their deeds.


VI. Resolving the Apparent Paradox

1. Faith Alone, but Never Alone

The principle “we are saved by faith alone, but the faith that saves is never alone” accurately captures the harmony between grace and the necessity of good works. Jesus’ emphasis on meeting practical needs illustrates what happens when the Holy Spirit renews a person from within: a life directed toward loving acts.

2. A Mirror of the Heart

In Matthew 25, the sheep never boast in their works; they seem almost unaware of doing anything extraordinary. Their acts of kindness overflow naturally, demonstrating the transformative power of saving grace (Matthew 25:37–39). Contrarily, the “goats” reveal that their hearts were never surrendered to God, as evidenced by their indifference.

3. Divine Love Leading to Action

This passage affirms that those who truly love and serve Jesus do so in concrete, compassionate ways. It is not the deeds themselves that earn redemption, but genuine faith in Christ propels those deeds. As Paul reaffirms: “God is able to make all grace overflow to you, so that…you will abound in every good work” (2 Corinthians 9:8).


VII. Practical Implications for Believers

1. Examining Our Hearts

Believers are urged to “work out [their] salvation with fear and trembling” (Philippians 2:12)—not meaning we earn salvation but that we manifest its reality in daily life. We should regularly examine our actions, motives, and habits, asking whether they align with a life transformed by Christ.

2. Compassion as a Fruit of Communion with God

A life of prayer and abiding in Christ fosters compassion. Serving those in need is not a checklist for merit; rather, it is a joyful expression of a regenerate heart in sync with God’s own mercy.

3. Confidence in God’s Grace

While the reality of judgment is serious, those who trust in Christ can have full assurance of salvation (1 John 5:13). Good works then become the natural outflow of gratitude and love for God, reflecting His character to the world.


VIII. Summary and Conclusion

The passage in Matthew 25:31–46 does not contradict salvation by grace through faith alone. Instead, it proclaims that on the day of judgment, the evidence of one’s faith will be visible in their concrete deeds of mercy. These deeds cannot earn salvation; they simply validate that the giver of those deeds had a heart regenerated by Christ’s saving power.

Scripture, from Genesis through Revelation, consistently affirms that salvation results from a spiritual transformation brought about by trusting Jesus. That transformation inevitably issues forth in a life of good works—acts of compassion and charity that mirror God’s love.

Thus, good works are necessary in that they testify to a believer’s faith. The question is never whether good works matter; rather, it is whether such works flow from a heart of faith or are performed as attempts to earn God’s favor. Matthew 25 keeps the believer grounded in the reality that a faith that is real will indeed be lived out in practical, loving action.
