The sermon opens in Matthew 6:25-34, a passage titled in the ESV "Do Not Be Anxious," and begins by naming a shared human condition before turning to the text. The preacher observes that every stage of life produces its own occasion for worry, that anxious thoughts are fundamentally irrational — always circling the unanswerable "what if" — and that the common cures people reach for, minimizing probabilities or preparing for every contingency, never actually work, since possibilities always outrun preparation. Scripture, by contrast, assumes anxiety as a real and recurring experience — the Psalms are full of "I am afraid" — and responds not by denying it but by speaking directly to the anxious heart, as when the Lord tells Israel in Isaiah 41, "fear not, for I am with you." Anxiety, the sermon argues, is not a probability problem but a heart problem, and so it requires not better odds but greater certainty. The sermon then organizes Jesus's teaching around three certainties meant to be applied to the anxious heart: that believers underestimate the Father's love for them, that worry accomplishes nothing, and that they are called to seek God's kingdom first.

On the first point, the sermon lingers on the word "value" in verse 26 — "are you not of more value than they?" — noting that Reformed Christians rightly resist a self-centered posture before God, yet Scripture still affirms that believers are precious in his sight. Drawing on Isaiah 43, the sermon corrects a common mistranslation of verse 4, arguing the text does not say believers are loved because they are precious, but rather that their preciousness flows from being loved — value is conferred, not earned. If God feeds the birds without their labor, and how much more has he made humanity his children rather than merely his creatures, then he who names the stars will not forget his own. The sermon presses further into Romans 8:32: since the Father did not spare his own Son but gave him up for all, anxious hearts have no grounds to doubt that a Father who has already given his most precious possession will withhold what is truly needed — even when he withholds what is merely wanted.

The second certainty addresses the futility of worry itself: verse 27's rhetorical question, that no one can add an hour to his life by being anxious, is treated as self-evidently true, since worry changes nothing about the future even while planning and preparing legitimately can. The sermon explains this futility using the doctrine of daily grace, contrasting a static picture of grace — like refueling a car that never becomes more efficient — with the biblical picture of grace as a refiner's fire that strengthens believers progressively through trials, and grace as a village well that never runs dry no matter how many draw from it. Because God has already given Christ, his Word, his Spirit, and the church, no additional store of grace needs to be stockpiled against future disaster; the very asking for "more grace" than has been promised mistakes the character of the gift. Manna given only for the day, and the ever-present pillar of cloud and fire, illustrate that God invites dependence on himself as the source, not merely on what he supplies.

The third certainty turns anxiety toward misplaced priorities. The sermon connects verse 25's "therefore" back to verses 19-21 on treasures on earth, arguing that anxiety exposes what the heart truly treasures — comfort, symbolized by food, and honor, symbolized by clothing, as in the comparison of the lilies surpassing Solomon's glory. The command in verse 33, to seek first the kingdom of God and his righteousness, is presented as a redirection of ultimate loyalty rather than mere comfort, paired with the promise that "all these things will be added," pictured through the image of a market seller who tips the scale generously in the buyer's favor. The sermon closes by citing Hudson Taylor's testimony of resting in God's will, and returns to the passage's final instruction — that each day's trouble is sufficient for itself, so that anxiety about tomorrow can be surrendered because the Father who is enough today will be enough tomorrow as well.
