The sermon opens a new mini-series on the lives of Isaac and Jacob in Genesis 25, reading verses 19 through 34. The preacher borrows an illustration from the Peanuts comic strip, where Lucy's second son is nicknamed "Rerun" because his birth repeats her disappointment of having another boy. In a similar sense, Isaac's life is a "rerun" of Abraham's: both marry barren wives, both face famine, and both fear a foreign ruler will take their beautiful wife, leading both patriarchs to the same lie that their wife is only a sister. The sermon argues that this repetition is not mere coincidence but God's way of showing that the same covenant faithfulness he displayed to one generation can be trusted by the next — a question the congregation, now approaching its own twenty-sixth anniversary and a generational transition, is urged to ask of itself: is the God who worked mightily in our parents' generation the same God we can rely on in new struggles and a new culture?

The sermon then traces three movements in the text. First, it considers Rebekah's barrenness against the backdrop of God's promise that Isaac's offspring would be as numerous as the stars. Unlike Abraham and Sarah, who took a shortcut through Hagar when the promise seemed delayed, Isaac responds to Rebekah's barrenness with twenty years of persistent prayer — a span calculated from his marriage at forty to Jacob and Esau's birth when he is sixty. The sermon draws a broader principle from this: "the longest delayed answers to prayer are often the most faith-building," because God's silence is not absence but the means by which he tests and deepens faith. It presses further into the harder case where prayer is never answered as hoped, illustrated by a woman who endured ten years of cancer, and insists that even there God's promise not to abandon his people in famine, nakedness, persecution, or death holds — that believers walk by faith rather than sight through the valley of the shadow, ultimately anchored in the cross, where God's love toward sinners can no longer be doubted.

Second, the sermon turns to the struggle of the two nations within Rebekah's womb and God's declaration that "the older shall serve the younger." It situates this within a repeated biblical pattern of sibling conflict — Cain and Abel, Isaac and Ishmael, Jacob and Esau, later Joseph and his brothers — arguing that the deepest cause of such conflict is not personality but divine election: those outside God's chosen line stand in perpetual enmity with those within it, a hostility traced back to the promise in Genesis 3 that the seed of the woman and the seed of the serpent would strike at one another until the final consummation resolves the struggle. Paul's exposition in Romans 9 is read to show that Jacob's election over Esau, decided before either was born or had done good or evil, rests entirely on God's sovereign call and mercy, not on any merit in Jacob — indeed Jacob will prove just as sinful as Esau. This doctrine of unconditional election, the sermon argues, is meant to assure believers today that their own standing rests solely on grace, not merit, and that even the flawed, favoritism-marked parenting believers may have received or given — as Isaac favored Esau and Rebekah favored Jacob — cannot ultimately overturn God's purposes; God works through, not despite, human sin and family dysfunction, so no one need be permanently defined by their past.

Third, the sermon expounds the sale of the birthright in verses 29-34. It highlights the Hebrew word describing Jacob, tam, meaning integrated or single-minded integrity — the same word used of Job — noting that even this good trait becomes an opening Satan exploits for manipulation. Yet the greater sin belongs to Esau, who despises his birthright, trading his place as ancestor of the Messiah for a single bowl of stew despite facing no real threat of death. The sermon applies this as a warning against surrendering eternal privilege — such as corporate prayer meetings, which the preacher laments have been sparsely attended over the recent holidays — for fleeting comfort or pleasure, and notes that Jacob himself pays dearly for his manipulation, waiting some forty years in the wilderness before actually enjoying the blessing he seized by deceit.

The sermon closes by contrasting Jacob's grasping with Christ, the true heir who, though equal with God, did not cling to his birthright but emptied himself, took the form of a servant, and was obedient to the point of death on the cross, so that those who trust him might receive the birthright of adoption as children of God, purchased at the price of his own blood. The congregation is invited to come to the Lord's Table in gratitude, resolving in the new year to walk faithfully, to prize what God gives rather than seek shortcuts, and to trust his unfailing love even where prayers remain unanswered.
