Episode Overview

In this sermon, Tim Keller explores “peace” as one of the fruits of the Spirit listed in Galatians 5, using Philippians 4:4–12 as his foundational text. He addresses the difference between externally managed calm and the deep, supernatural peace that comes through the Christian gospel. Keller unpacks the character of Christian peace, the disciplines required to nurture it, and the “secret” to accessing a peace that transcends understanding—even through suffering, loss, and uncertainty. The sermon draws from Christian doctrine, personal anecdotes, philosophy, and memorable illustrations to guide listeners into practical and theological depths of lasting peace with God.

Key Discussion Points & Insights

1. The Character of Christian Peace

(Starts ~02:39)

• Supernatural vs. Self-Controlled Peace

  • There’s a distinction between “a morally restrained heart and a supernaturally changed heart,” with the latter being the goal of the gospel.

    “There’s a difference between controlling, suppressing the natural self centeredness and insecurity of the heart through willpower and seeing it permanently change through the power of the Holy Spirit.” (Tim Keller, 02:39)

• Inner Calm and Equilibrium

  • Paul, in prison and facing death, speaks of a contentment born not from talent or temperament but from “learning” peace—implying it can be cultivated by anyone.
  • True Christian peace manifests as inner equilibrium regardless of external circumstance (“I have learned the secret of being content in any and every situation...” [Phil 4:12]).

• A Sense of Being Protected

  • The “peace of God will guard your hearts and your minds” uses a military metaphor: peace as a protective, encompassing presence, rather than mere absence of negative thoughts or worries.
  • Unlike other traditions that urge avoidance or suppression of negative or dangerous thoughts, Christian peace comes from “not expelling negative thoughts... but the presence of God himself” (07:14).

• Resilience Analogy

  • Christians experiencing God’s peace are likened to solid rocks unmoved by crashing waves: “And Paul is like that… All the ways of life could not break him. And he says, this isn’t a natural talent. You can learn this.” (Tim Keller, ~09:20)

2. The Three Disciplines to Cultivate Peace

(Starts ~11:55)

a. Thinking (Doctrine and Perspective)

• Engage Deeply with Christian Doctrine and Reality

  • Paul urges meditation on “whatever is true… noble… right” (Phil 4:8). In Paul’s usage, these words refer to central Christian truths.
  • In contrast to self-help and modern stress management that focus on technique or distraction, Christian peace comes from grappling with life’s hard questions from a gospel perspective.

    “Christian peace comes from thinking out the implications, thinking… what are the true and the right. What’s the Christian doctrine?” (Tim Keller, ~15:48)

• “Stupid Peace” vs. “Smart Peace”

  • “Stupid peace” comes from avoidance or numbing (“ho, ho, ho to the bottle I go”), while “smart peace” arises from active, thoughtful engagement with Christian belief.

b. Thanking (Gratitude in Uncertainty)

• Thanksgiving in Unanswered Requests

  • The “antidote” to anxiety is prayerful request “with thanksgiving”—not for having received, but in the act of requesting, trusting that God is wise and sovereign.

    “When a child of mine makes a request, I always give that person what he or she would have asked for if they knew everything I know. Do you believe that? To the degree you believe that, you’re going to have peace…” (Tim Keller, 23:55)

  • Cites Romans 8:28 and Jesus’ crucifixion as proof that God works even the worst events for good, beyond what we now see.

• Personal Anecdote

  • Keller humorously tells of praying for a romantic relationship as a young man, illustrating that God’s answers exceed our partial understanding, and that trust in his sovereignty breeds peace.

c. Loving (Rightly Ordered Affections)

• More Than Right Belief—Right Love

  • Drawing from St. Augustine, Keller explains that true tranquility comes only from loving the “immutable” (unchanging) — God himself.
  • Stoic self-mastery is inadequate: you cannot even be certain of maintaining your own virtue. Only love of God brings indestructible peace.

  “Only love of the immutable can bring tranquility. Only love of the immutable. What’s the immutable? That which cannot change…” (Tim Keller, ~27:30)

• Augustine’s Confessions

  • Keller quotes Augustine’s poetic meditation on loving God over all passing joys (“What do I love when I love thee?... they are those which space cannot contain, which time cannot bear away… This is what I love when I love my God.” [~29:35])

3. The Secret of Peace

(Starts ~31:55)

• Peace Is Not Achieved by Willpower Alone

  • Keller warns that simply “trying” to love God on your own is impossible—God abstractly considered is not enough for the heart.

• Peace “in Christ Jesus”

  • The secret, according to Paul, is not just generic belief in God but centering both “heart and mind” in Christ Jesus.
  • Isaiah 57 is invoked to illustrate the restless sea of the human heart without God, and Keller stresses that restlessness is the result, the “natural consequence,” of loving anything above God.

• Jesus as the Substitute: The Cross and Restlessness

  • Jesus, on the cross, loses all peace—he takes on all the cosmic restlessness and distress of the world so that we might receive his peace.

    “Jesus lost all of his peace so you could have eternal peace. And looking at that, that is what will get you through. That’s what will make him lovely.” (Tim Keller, 35:51)

• Illustration: Horatio Spafford and “It Is Well With My Soul”

  • Spafford, having lost his fortune and his four daughters, writes of peace “like a river”—and centers his hope on Christ’s finished work, not on external circumstance or self-worth.

    “Why would a man dealing with his grief, seeking the peace of God, the peace like a river, spend the entire thing on Jesus?... All the punishment fell on him… The Bible gives you a God that says, ‘I’ve lost a child too, but not involuntarily, voluntarily, for your sake.’” (Tim Keller, ~36:55)

Notable Quotes and Memorable Moments

• On Christian Peace vs. Numbing Escapism

  “If you’re a Christian today and you believe all that doctrine and you are not at peace, you’re not thinking.” (Tim Keller, 15:41)

• On Prayerful Trust

  “When a child of mine makes a request, I always give that person what he or she would have asked for if they knew everything I know.” (Tim Keller, 23:55)

• On “Thinking, Thanking, Loving”:

  “There’s thinking… then thanking is the second discipline. But loving, loving is the last one.” (Tim Keller, 20:40)

• Augustine on Loving God

  “God alone is the place of peace that cannot be disturbed. And God will not withhold himself from your love unless you withhold your love from him.” (Tim Keller, 28:41)

• On the Cross and Christ’s Peace

  “Jesus lost all of his peace so you could have eternal peace...” (Tim Keller, 35:51)

Conclusion

Tim Keller’s sermon on peace challenges listeners to move beyond circumstantial calm and willpower. Christian peace, Keller explains, is a gift of God—but also a discipline requiring deep meditation on gospel truths (“thinking”), ongoing gratitude in all circumstances (“thanking”), and loving God above all else (“loving”). The ultimate “secret” of this peace lies in communion with Christ: seeing his loss of peace on the cross as providing our eternal peace. Through vivid stories, historical wisdom, and biblical insight, Keller offers an invitation to experience an unshakeable peace, “like a river,” rooted in the love and sacrifice of Jesus.
