The sermon addresses Matthew 25:31-46, the final passage in a longer block of teaching in which Jesus answers his disciples' questions about his coming as king and the end of the age. The preacher sets the scene: the disciples expected Jesus to become king through strength and conquest, but Jesus reveals he will reign instead by dying for those he came to save, and that no one knows the day of his return. This passage closes that teaching with a picture of the final judgment, where the Son of Man comes in glory with his angels, sits on his throne, and separates all the nations as a shepherd separates sheep from goats.

The sermon insists on taking this teaching about heaven and hell seriously and literally, resisting the instinct — common even among churches — to soften or hide it for fear of frightening newcomers. The preacher acknowledges that no one enjoys hearing about eternal punishment, but argues that truth, not preference, must govern belief. Jesus himself, known for kindness and mercy toward sinners, is the one who most clearly and repeatedly teaches about hell, so the two cannot be separated.

The sermon explains why Jesus alone has the right to judge every human being: first, because he is holy and has never sinned, and therefore has never forfeited the moral standing needed to judge others, unlike any human judge who is himself guilty; second, because he is the Creator who made everyone for himself, giving him rightful authority over how his creatures live and what becomes of them. On that day everyone stands guilty, and the sentence is not merely physical death but a "second death" — eternal separation from God. Yet God's holiness is not his only attribute; the sermon turns to the account of the woman caught in adultery in John 8, where Jesus, the only person present with the right to condemn her, instead forgives her, foreshadowing that he himself will bear the punishment sinners deserve. Their judgment does not fall on them because Jesus paid it fully at the cross.

From here the sermon moves to assurance: how can anyone know they belong among the sheep rather than the goats? Drawing together threads from across Jesus' teaching, the sermon names three inseparable marks of those destined for the kingdom — belief in Jesus as the Son of God who died for sinners, repentance from sin, and obedience that flows from a transformed heart. These three are gifts of grace, given together by God, never found in isolation from one another, yet also given as commands. In this specific passage, Jesus adds a further evidence: love for "the least of these my brothers," identified as fellow believers, since Jesus elsewhere calls his disciples his brothers and sisters and identifies himself so closely with his people that persecuting them is persecuting him, as with Saul on the Damascus road.

The sermon illustrates this costly love through the early church, where Christians risked property, social standing, and their lives to feed, clothe, and visit persecuted believers, sometimes belonging to Caesar's own household. This love was not calculated or self-conscious — the sheep in the parable are genuinely surprised to learn that caring for Christ's people was caring for Christ himself — but arose naturally from hearts that had been changed by knowing and loving Jesus.

Anticipating an apparent contradiction with salvation by grace through faith alone (Ephesians 2:8-9), the sermon lays out a Reformed resolution: salvation is received through faith alone, apart from works, yet genuine faith inevitably and necessarily produces works, including visible love for the church. Faith without any resulting love is not saving faith at all. The sermon is careful to distinguish this from teaching salvation by faith plus works, and equally careful to note that love for Christ's brothers does not replace or diminish love for neighbors generally, recalling the parable of the Good Samaritan, but adds a further, specific test bound up with shared faith in Christ.

The sermon closes by correcting two errors it observes in the congregation: claiming to love Jesus while withholding love from his people because of past hurt, and treating church ministries as ends in themselves rather than as means of loving people. It urges the church, described as culturally prone to substitute politeness for love, to both give and receive costly help from one another, following the pattern of Christ's own self-giving love, since loving Jesus' people is the church's ongoing way of repaying a debt to Jesus that can never otherwise be repaid.
