1. Introduction to the Sermon

[00:04 - 00:30]

Tim Keller opens the episode by introducing a special selection of sermons emphasizing themes such as rest, idolatry, and integrating faith with work. He underscores the central truth that the gospel "truly changes everything."

Quote:

"This month's messages highlight themes like rest, idolatry and integrating our faith with our work, each one rooted in the truth that the gospel truly changes everything."
— Tim Keller [00:04]

2. Reading of the Parable of the Prodigal Son

[00:30 - 03:40]

An unknown reader narrates the Parable of the Prodigal Son from Luke 15:1-32, setting the stage for Keller’s in-depth analysis. The parable contrasts the behaviors and attitudes of the younger and older sons, highlighting themes of repentance, forgiveness, and familial relationships.

3. Exposition and Interpretation

[03:40 - 39:58]

Tim Keller delves deeply into the parable, offering a comprehensive analysis divided into several key sections:

a. Understanding the Two Sons

[03:40 - 12:00]

Keller emphasizes that the parable is not just about the younger son but intricately involves both sons—the younger and the older—each representing different human approaches to God.

Quote:

"It's a great mistake to think that this is a story about one son. It's a story of two sons."
— Tim Keller [03:40]

b. Redefining God

[12:00 - 20:53]

Keller challenges traditional perceptions of God by illustrating a father in the parable who defies the patriarchal norms of his time. This father’s unconditional love, compassion, and willingness to endure rejected love redefine the biblical concept of God as both authoritative and deeply affectionate.

Key Points:

• Traditional views of God as strictly patriarchal are incomplete.
• Jesus presents God as embodying both power and tenderness.
• Quote:
  "Jesus Christ gives us a father unlike any father of that time. His emotional abandon, his generosity, his willingness to receive the agony of rejected love."
  — Tim Keller [12:15]

c. Redefining Sin

[20:53 - 35:00]

Keller expands the concept of sin beyond mere wrongdoing. He posits that both the younger and older brothers are lost—not just the younger in his rebellion but also the older in his self-righteousness. This duality illustrates that sin is not only about transgressions but also about the inability to connect with God genuinely.

Key Points:

• Two Types of Lostness:
  • Younger Brother: Represents self-indulgence and moral failings.
  • Older Brother: Symbolizes moral conformity and self-righteousness.
• Quote:
  "The elder brother is lost in his goodness. He's lost because of it."
  — Tim Keller [21:30]

d. Redefining Salvation

[35:00 - 39:58]

Salvation, according to Keller, transcends traditional avenues like moral conformity or self-discovery. It requires:

1. Initiating Love of the Father: God’s proactive love seeks out individuals.
2. Repentance Beyond Sins: Acknowledging the desire to control rather than genuinely seeking reconciliation.
3. Understanding the Cost of Salvation: Recognizing the profound sacrifice made on behalf of the individual.

Key Points:

• Three Essentials for Salvation:
  1. Initiating love from God.
  2. Repentance that addresses underlying motives, not just actions.
  3. A transformative understanding of the cost of salvation.
• Quote:
  "Repent for something besides sins. You have to recognize the desire to be your own savior and lord."
  — Tim Keller [35:45]

4. Application to Modern Life

[21:56 - 39:58]

Keller applies the parable to contemporary contexts, addressing both "younger brother" types who seek self-discovery and "elder brother" types who adhere to moral conformity. He critiques both approaches as insufficient for true salvation and emphasizes the need for a relationship with God rooted in humility and grace.

Key Points:

• Critique of Modern Approaches:
  • Moral Conformity: Obedience out of duty, leading to judgmentalism and superiority.
  • Self-Discovery: Pursuit of personal authenticity, often resulting in self-justification and control.
• Call to Transformation:
  • Embrace a Christian life motivated by love and gratitude, not mere duty or self-interest.
  • Recognize the transformative power of God's initiating love and the true cost of salvation.
• Quote:
  "Gospel people obey God to get God to resemble Him, to love Him, to know Him, to delight Him."
  — Tim Keller [25:10]

5. Conclusion

[39:58 - End]

Keller concludes by encouraging listeners to reflect on their spiritual posture—whether they align with the self-indulgent younger brother or the self-righteous older brother. He invites both groups to embrace the transformative grace offered through Christianity, highlighting that true salvation involves a profound redefinition of one's relationship with God.

Final Quote:

"We will never be elder brothers until we see and are melted by what our true elder brother did for us."
— Tim Keller [39:30]
