The sermon opens with a modern parable of its own: in 1962 an Italian junk dealer named Luigi Lo Rosso found a rolled-up painting in the basement of a villa near Capri. He thought it odd but mildly interesting, framed it cheaply, and gave it to his wife, who hung it in their home and later in the family restaurant for nearly fifty years. Only in the 1980s did his son, learning about Picasso in school, suspect its true origin. Decades of authentication followed until, in September 2024, the painting was confirmed genuine and valued at $9.6 million. The preacher uses this story of hidden, unrecognized value to introduce Jesus's twin parables in Matthew 13:44-46, read at the start of the service: the kingdom of heaven is like treasure hidden in a field, and like a fine pearl sought by a merchant — in both cases, the one who finds it sells everything he has, with joy, to obtain it.

The sermon frames the kingdom of heaven as the reign of Christ, inaugurated in his coming, unfolding through his earthly ministry, and reaching its climax in his death and resurrection. Though Christ's kingship is not yet fully visible, it will be manifest at his return, when every knee bows and every tongue confesses him Lord. This kingdom, the sermon argues, is simultaneously present in the world and hidden from many — a mystery once veiled in the Old Testament but now disclosed through the apostles and proclaimed by the church. Citing 2 Corinthians 4:3-4, the sermon explains that the gospel remains veiled specifically to those who are perishing, whose minds the god of this age has blinded so they cannot see the light of the gospel of the glory of Christ. Like the children's character Humpty Dumpty complaining he cannot see anything while his eyes are shut, unbelievers cannot perceive the treasure until God graciously opens their spiritual eyes — a work the sermon insists is entirely of grace, since all people are by nature spiritually dead and blind.

The sermon then contrasts the parables with the account of the rich young ruler, who asks Jesus what he must do to inherit eternal life. When Jesus tells him to sell all he has and follow him, the man goes away sorrowful, because he has great wealth — the Bible's telling detail. Unlike the men in Matthew 13 who sell everything with joy, the rich young ruler cannot bring himself to do so, revealing an inner conflict: he values eternal life, yet not more than his possessions. The sermon invokes Augustine's line that God has made us for himself and our hearts are restless until they rest in him, and John Piper's statement that no one is truly a Christian who does not embrace Jesus gladly as his most valued treasure. The pearl merchant is set against the historical backdrop of ancient pearl diving, in which divers tied stones to themselves to sink quickly, risking their lives for a single pearl — underscoring how much this treasure is worth pursuing.

Turning to application, the sermon holds joy and cost together: both finders in the parables act joyfully, yet both pay a real price, selling everything. Quoting Dietrich Bonhoeffer's The Cost of Discipleship — "the grace of God is free, but not cheap" — the sermon clarifies sola gratia: salvation costs us nothing because it cost God everything, the life of his own Son. Using illustrations of oxygen (free yet precious, unappreciated until breath is taken away), a fictional "Rich Flu" film in which the wealthy give away fortunes to survive, and parents who will sell anything to rescue a child from addiction, the sermon argues that recognizing Christ's supreme worth inevitably reorders one's whole life, like the centered axle of a wheel that keeps every spoke functioning. It commends a young man named Jack, who left a $113,000 salary to attend Westminster Theological Seminary without pay, and closes with the story of Jim Elliot and four companions, missionaries martyred in Ecuador in 1956 by the people they had come to reach, having refused to use the weapons they carried. Elisabeth Elliot's words are cited as the sermon's final word: "He is no fool who gives what he cannot keep to gain what he cannot lose."

Bible Verses Used

• Matthew 13:44-46: The two parables of the hidden treasure and the pearl of great price that anchor the sermon's central claim — the kingdom of heaven, found in Christ, is worth surrendering everything to possess.

• Matthew 19:16-22 (the rich young ruler): Used as a contrasting case study — a man who, unlike the finders in the parables, values his wealth above Christ and walks away sorrowful rather than selling all with joy.
