Introduction

In the episode titled "The City of God," Pastor Tim Keller delves into the profound questions surrounding faith and suffering, drawing insights from the Book of Hebrews. Addressing believers grappling with life's hardships, Keller explores the concept of Christians as "resident aliens" navigating the tension between their spiritual citizenship and earthly residency.

Understanding Resident Aliens (00:01:57)

Keller begins by contextualizing the audience of the Book of Hebrews—individuals enduring significant trials and questioning the nature of God's love amidst their suffering. He introduces the central metaphor of being "resident aliens," a term that encapsulates the duality Christians experience:

• Aliens vs. Residents: The Greek term translated as "aliens" refers to "resident aliens"—permanent residents who are not citizens of the land they inhabit.

• Tension of Duality: Embracing God introduces a transforming power that creates a tension between living in the current society and holding allegiance to a heavenly city.

Notable Quote:

“When you embrace the living God by faith, into your life comes transforming power and a deep tension, a duality. And if you try to resolve it, you lose that transforming power.”
— Tim Keller (10:15)

Two Cities in Conflict (00:05:30)

Keller outlines the existence of two distinct cities:

1. The Earthly City: Represents current societal structures, cultures, and systems based on power and pride.
2. The City of God: A heavenly city God is preparing, characterized by justice, peace, and service.

He emphasizes that these two cities are inherently in conflict, yet only one truly serves the other.

Notable Quote:

“The city of God, the heavenly city, is all through these last chapters... a city in the future that will never pass away.”
— Tim Keller (15:05)

Conflict with Cultural Norms (00:10:45)

Keller explores how Christian beliefs often clash with both collectivistic (traditional, hierarchical) and individualistic societies:

• Sexual Ethics: The Bible's teachings on sex promote community building and committed relationships, conflicting with both prudish traditional cultures and liberal individualistic societies.

• Truth and Morality: The absolute truth presented in the Bible challenges individualistic notions of personal truth and traditional cultures' use of truth to marginalize others.

Notable Quote:

“The Bible says you must accept truth, not because it works for you as an individual, but because it's true to what is there.”
— Tim Keller (12:30)

Rejecting the "Get Up to Date" Mentality (00:19:42)

Addressing modern skepticism, Keller argues against the notion that Christianity must conform to contemporary standards to remain relevant:

• Enduring Truths: He references Augustine's "City of God" to illustrate that orthodox Christian beliefs have withstood the test of time despite cultural shifts.

• Timeless Relevance: Emphasizes that attempting to "get up to date" diminishes the transformative power of Christianity, making it susceptible to becoming obsolete.

Notable Quote:

“According to the Book of Hebrews, what the Bible says, if you embrace what the Bible says, you are adopting the values, the practices, and the beliefs of the city of God, which is to come and will never pass away.”
— Tim Keller (19:42)

Resolving Sectarianism and Chaplaincy (00:25:00)

Keller critiques traditional approaches to religion—sectarianism and chaplaincy—highlighting their limitations:

• Sectarianism: Excludes outsiders by enforcing strict beliefs and standards, akin to fundamentalism.

• Chaplaincy: Engages with society superficially without transformative impact, resembling mainline religions.

• Resident Aliens as a Balanced Approach: Advocates for a model where Christians are fully engaged in societal flourishing while maintaining their distinct spiritual identity.

Notable Quote:

“The only way we're ever going to become resident aliens is if the fundamental structures of our heart are changed by an encounter with Jesus Christ.”
— Tim Keller (28:15)

Transformative Power Through Jesus Christ (00:35:00)

Central to Keller's thesis is the transformative influence of Jesus, who exemplifies loving a city that rejects Him:

• Jesus' Example: Suffering and being crucified outside the city gate serves as a model for Christians to bear disgrace while loving their surrounding society.

• Heart Transformation: Emphasizes that genuine change comes from an internal encounter with Christ, not merely external efforts to conform or resist.

Notable Quote:

“Jesus Christ loved that city, but he lost that city outside the gate. He was being cast out in our place so that God can accept us in spite of our failures.”
— Tim Keller (39:00)

Conclusion: Embracing the Identity of Resident Aliens (00:45:30)

Keller wraps up by reiterating the call for Christians to embody the identity of "resident aliens":

• Engaged Counterculture: Christians should actively work towards the common good, influencing society positively while holding onto their spiritual convictions.

• Dependence on the Gospel: True transformation and the ability to live out this dual identity stem from a deep understanding and acceptance of the Gospel.

Final Notable Quote:

“We are resident aliens. Aliens. What does it mean to say that people who believe in God through Jesus Christ are aliens?... the Bible says, if you embrace what the Bible says, you are adopting the values, the practices and the beliefs of the city of God, which is to come and will never pass away.”
— Tim Keller (45:30)

Closing Prayer (00:55:00)

The sermon concludes with a heartfelt prayer, asking for divine assistance in embodying the role of resident aliens and faithfully representing the values of the City of God amidst earthly challenges.

Key Takeaways

1. Dual Citizenship: Christians navigate life as residents of an earthly city while holding citizenship in the heavenly City of God.

2. Cultural Tension: Biblical truths often clash with both traditional and modern individualistic cultures, necessitating a stance of being countercultural yet engaged.

3. Transformative Power of Faith: Authentic Christian living arises from an internal transformation through Jesus Christ, not merely external conformism or rebellion.

4. Challenging Religious Norms: Rejects both exclusionary sectarianism and superficial chaplaincy, advocating for a model that truly influences and transforms society.

This episode of Tim Keller's sermon offers a profound exploration of Christian identity and purpose within a world that often misunderstands or opposes biblical values. By embracing the role of resident aliens, believers are called to live distinctively while actively contributing to societal flourishing, grounded in the transformative power of the Gospel.
