Main Theme / Purpose

In this sermon, Tim Keller explores the profound biblical command to "be filled with the Spirit" (Ephesians 5:18). Keller unpacks the meaning of spiritual fullness, how it contrasts with and relates to other sources of joy or courage (like alcohol), and outlines the practical steps and signs of a Spirit-filled life. He emphasizes the transforming work of the Spirit, rooted in grace, that produces both humble realism and surging joy in believers who are deeply grounded in the gospel.

Key Discussion Points & Insights

1. Understanding “Being Filled with the Spirit”

(01:26 – 10:50)

• Command, Not Suggestion: Paul’s urging to “be filled with the Spirit” is a directive, not merely an aspiration.
  “He commands, be filled with the spirit.” — Tim Keller [01:29]

• Comparison with Alcohol (Drunkenness):

  • Similarity: Both being drunk and being filled with the Spirit can lead to boldness and happiness. At Pentecost, observers thought the Spirit-filled disciples were drunk because of their exuberance.
    • “The only time they ever see people as brave and as happy as people who are filled with the spirit is people who are drunk.” — Tim Keller [03:45]
  • Dissimilarity: Alcohol numbs reality (depressant), leading to a false, diminished sense of courage and ease, while the Spirit sharpens and expands awareness—heightening reality.
    • “Alcohol makes you brave and happy by depressing your brain and showing you less of reality. But the fullness of the spirit operates in exactly the opposite way.” — Tim Keller [06:38]

• Biblical Illustration (Elisha in 2 Kings 6):
  Elisha’s servant is terrified by looming enemies, but Elisha’s prayer opens his eyes to "all of reality"—the spiritual dimension (God's protection), which brings courage. The Spirit brings this heightened awareness, not escapism.

  • “The fullness of the Spirit is not giving you joy and courage by showing you less of reality, but showing you more of reality.” — Tim Keller [08:47]

• C.S. Lewis Reference:

  • Christianity is not for escapism or seeking comfort but for deep engagement with reality through God’s truth.
    • “I didn't go to Christianity to make me happy. I always knew a bottle of port would do that. If you want to make yourself happy and comfortable, I don't recommend Christianity.” (Paraphrased quote) — C.S. Lewis, cited by Tim Keller [09:45]

2. Marks of a Spirit-Filled Life

(10:50 – 22:15)

A. Humble Realism

• Spirit-filled people possess wisdom—a grounded awareness of reality, not naïve optimism.

  • “To be wise means to be realistic, not idealistic, not naive, not having rosy colored glasses. A wise person is savvy.” — Tim Keller [11:52]

• Paradox of sorrow and joy (2 Corinthians 6):

  • “We’re sorrowful, yet always rejoicing. We’re poor, yet we possess everything.” — Tim Keller quoting Paul [12:30]

• Not self-inflated: Spiritual joy is not based on one’s achievements or positive thinking, but anchored in God.

  • “The joy of the Holy Spirit is like the stars. … The stars get brighter and brighter as the night gets darker.” — Tim Keller [14:11]

B. Surging Joy

• This joy allows continual thankfulness, regardless of circumstances:

  • “A person filled with the spirit always gives thanks to God the Father for everything. In the name of our Lord Jesus Christ.” — Tim Keller [17:17]

• The power of the cross and grace:

  • God hates evil, but uses suffering (supremely in Jesus) to bring about redemption.
  • Spirit-filled joy does not ignore problems but finds reason for gratitude even in suffering, because of a deepening understanding of God’s redemptive work.

C. Delight in God’s Presence

• Spirit-filled life is characterized by an active, almost musical delight in God’s presence.
  • “To sing and make music in your heart to the Lord means this is a person who so has a sense of God’s presence and such a delight in God’s actual presence that that person would put it into a song if he could.” — Tim Keller [19:31]

D. Edifying Community

• Spirit-filled people encourage and build up one another by sharing what God is doing in their lives.
  • “Spirit filled people create an incredible kind of Christian community.” — Tim Keller [21:10]

3. How to Be Filled with the Spirit

(22:15 – 31:55)

• Example of Jesus (Luke 10, Matthew 11):

  • Even Jesus needed and experienced the fullness of the Spirit, marked by an “explosion of joy through the Holy Spirit.”

    • “Jesus, full of joy through the Holy Ghost, exulted and said, ‘I praise you, Father…’ ” — Tim Keller quoting Scripture [24:21]

  • God reveals Himself not to the wise or accomplished, but to those who are spiritually humble (“little children”).

    • “He doesn’t reveal himself to the accomplished... He reveals himself to little children. That’s a spiritual phrase... the helpless, the weak, the people who know they’ve got nothing…” — Tim Keller [25:11]

• Grace as Central:

  • Jesus lost the fullness of the Spirit at the cross (forsaken in our place) so that we do not have to, even though we deserve it.

    • “Jesus Christ was standing in our place and he was abandoned. He got the abandonment that David deserved, that you and I deserve. … So he lost the fullness of the spirit so you and I could have it, even though we’re sinners.” — Tim Keller [27:48]

  • The key to being filled with the Spirit: Let grace move you from the inside out until there is “an explosion of joy, the joy of the Holy Spirit.”

    • “Look at grace, grace, grace until there’s an explosion of joy, the joy of the Holy Spirit.” — Tim Keller [29:03]

• Practices for Fullness:

  • First, be filled with Christ—come as a spiritual child, relying only on grace.
  • Then: devote disciplined time to the Word, prayer, meditation, worship (corporate and private).
  • Let the truths of the gospel become “theology on fire in your life.”
    • “The experience of the Spirit is the truth on fire in your life. It’s theology on fire in your life. And that takes study and that takes prayer and that takes the means of grace.” — Tim Keller [30:28]

Conclusion

Tim Keller’s sermon persuasively argues that real spiritual fullness isn’t an emotional high, but a grounded, resilient, gospel-rooted joy and awareness. The Spirit strengthens us not by making us forget reality, but by opening our eyes to more of it—especially to Christ’s redeeming love. This fullness comes not from striving but from dwelling on grace, deep prayer, scripture, worship, and mutual encouragement—with Christ always at the center.
