The sermon opens with a reading of Genesis 22:1-19 and briefly sets the scene from Genesis 21: after twenty-five years of waiting, God finally fulfilled his promise of an heir to Abraham and Sarah in the birth of Isaac. Ishmael and Hagar have since been sent away at God's own instruction, so Isaac now stands as Abraham's only remaining son, the child of promise through whom Abraham's offspring were to become as numerous as the stars and the sand, and through whom all the nations of the earth would be blessed. It is against this backdrop that God's command in verse 2 lands with such force: take your son, your only son, whom you love, Isaac, and offer him as a burnt offering. The sermon stresses that this is a test, not a temptation — God tests to refine and mature faith, while Satan tempts to destroy — and that Abraham himself does not know he is being tested. All he knows is the bare command, repeated with deliberate emphasis on "your son," "your only son," and "whom you love," so that there is no ambiguity about what is being asked of him.

The sermon walks through the narrative slowly, noting details that reveal Abraham's inner turmoil even as he obeys. Unlike his earlier, bold intercession for Sodom and Gomorrah, Abraham raises no argument here; he simply rises early and prepares. Yet the slightly disordered sequence of his preparations — saddling the donkey, gathering the servants, and only then splitting the wood — is read as a sign of his inward agitation despite outward obedience. The three-day journey to Moriah is highlighted as a deliberate narrative device: prolonged suffering is harder to bear than sudden suffering, and Abraham must lie beside his sleeping son for three nights knowing what the next day may require. His ambiguous words to the servants — "we will worship and we will come back to you" — are presented as possibly an early flicker of resurrection faith (as Hebrews later suggests) or simply an unresolved inner struggle; the text does not say. Isaac's carrying of the wood up the mountain is drawn out as a clear foreshadowing of Christ carrying his cross to Golgotha, and the climb itself is described as "a deafening silence," full of unspoken anguish. When Isaac finally asks where the lamb is, Abraham's answer — "God himself will provide the lamb" — is read as the moment his heart becomes fully surrendered, and it proves prophetically true both of the ram caught in the thicket and, typologically, of Isaac's own near-sacrifice.

Three reflections follow. First, drawing on A. W. Tozer, the sermon argues that God's real aim was never to have Isaac killed, since the promise depended on him, but to remove Isaac from the throne of Abraham's heart. Isaac — though himself a good gift, the fulfillment of promise — had the potential to become an idol, and the sermon observes that idols are often not obviously sinful things but good gifts (a spouse, a child, achievement, comfort, money) that gradually take the place only God should occupy. The recent moral fall of a well-known Reformed preacher, Stephen Lawson, is used as a sober illustration: rather than concluding "if he can fall, what hope do I have," the sermon insists this should drive believers to stop trusting in any human being — pointing back to David's far graver sins — and to rest entirely in Christ, since all people, including the preacher himself, are sinners in need of grace.

Second, the sermon locates the answer to idolatry in beholding Christ. It turns to John 8:56, where Jesus says Abraham rejoiced to see his day, suggesting Abraham had some insight into the substitutionary lamb pointing to Christ. Roughly two millennia later, God's own beloved, only Son willingly carried wood up a hill near Moriah, Golgotha, but this time no angel intervened; the only cry was Jesus' own, "My God, my God, why have you forsaken me?" — a cry the sermon says believers themselves must answer, because it was for the love of the world that the Father did not spare his Son. A modern illustration from the film Brothers, about a soldier whose PTSD nearly drives him to kill his own family, is used by contrast: God's giving of his Son was not born of trauma or compulsion but of measureless love, and it was the only way of salvation — there was no alternative, since God who created the universe merely by speaking still could not save fallen humanity except by sending his only Son to die.

Third, the sermon urges obedience in light of this love. The threefold repetition of Abraham's covenant blessing in verses 12, 15, and 18 shows that obedience flows from grace already given and from grace still promised. Believers are called to a daily, ongoing battle against whatever idols still compete for the throne of the heart, trusting that knowing Christ's surpassing worth makes even costly obedience feel not like loss but like joyful exchange, as with the man who joyfully sells all he has for a treasure of far greater worth. The sermon closes with an invitation to repentance and renewed surrender, and a prayer that hearers would see idolatry as repugnant and cling wholly to Christ.
