The sermon opens the third and final movement of the Sermon on the Mount. Matthew 5 unfolds the kingdom of God, chapter 6 the love of God, and now chapter 7 turns to the righteousness of God, as Jesus, speaking with the authority of the King, issues the laws of his kingdom and pronounces judgment on the unrepentant. The sermon insists that Scripture never sets God's love against God's righteousness; rather, God's love has no meaning apart from his justice. A love that only provides and never guides, that always forgives and never demands change, is not divine love but indulgent sentimentality. God's righteousness is unchanging — "I am who I am" — and it is precisely because he will not compromise his justice that the cross was necessary: in love, God sent Christ to bear the punishment that his own righteousness required, so that his love and his justice are both satisfied rather than traded off against each other.

Against that backdrop, the sermon takes up the notoriously misused command "judge not" and works through three things it does not mean. First, it does not forbid moral judgment altogether; Jesus himself condemned the hypocrisy of the religious leaders and the false teaching of wolves in sheep's clothing, and every human society, believing or not, lives by moral judgments it cannot avoid making. Second, it does not mean Christians may never address sin or correct one another. Galatians 6:1 calls believers to restore a brother caught in transgression, and Matthew 18 instructs disciples to go and tell a brother his fault — the church is called to mutual accountability, exercised, as the account of the woman caught in adultery shows, on the basis of full forgiveness demanding full obedience, not judgment substituting for grace. Third, it does not mean teaching or teachers are beyond scrutiny; Matthew 7:15–16 itself warns of false prophets known by their fruit, 1 John urges testing the spirits, the Berean believers in Acts 17 examined Paul's preaching against the Scriptures daily, and Paul in Galatians 2 rightly rebuked Peter for compromising the gospel out of fear of the circumcision party.

Having cleared away these misreadings, the sermon states positively what "judge not" does mean: that God alone is the final judge of all people. The passive construction of the Beatitudes-style Jewish idiom points to God as the unnamed judge in view, and believers are already freed from the verdicts of human courts of opinion because their standing rests on God's verdict alone, as Paul insists in 1 Corinthians 4 when he refuses to be judged by any human court, or even to judge himself, because it is the Lord who judges him. Even so, Paul did make judgments — but only ever as God's mouthpiece, not as one setting up his own private tribunal. The sermon presses this into the life of the hearers: parents, in particular, are warned against becoming the ultimate judges of their children's lives, punishing personal inconvenience more harshly than actual sin against God, when they should instead be pointing children toward God's own standards.

Because human judges cannot see the heart as God does, and because human judges are themselves guilty of the very sins they condemn in others, judging another exposes the judge to the same verdict he pronounces — like a drug dealer calling the police on his own buyer. The measure used in judging becomes the measure by which the judge himself is measured, not because God arbitrarily conforms his standards to ours, but because there is an unbreakable link between having received God's forgiveness and being willing to extend it to others; a person who refuses to forgive shows himself untouched by the forgiveness he claims to have received. Because Christ has already borne God's judgment on behalf of the repentant, no human has any higher court of appeal to reopen that verdict — to keep condemning someone God has forgiven is, in effect, to declare the blood of Christ insufficient. The sermon closes with a pastoral appeal, echoing Jesus' words about leaving one's offering to be reconciled first: hearers who are withholding forgiveness from a brother or sister are urged to look to the cross, receive the Spirit's help to remove the log from their own eye first, and then approach others' faults not with a judgmental spirit but with Christ-like love that both forgives and sanctifies.
