Overview of the Episode
In this thought-provoking sermon, Tim Keller explores the biblical meaning of "rich in faith" through the lens of the eighth commandment, "Thou shalt not steal." He argues that Christianity calls believers not merely to avoid stealing but to be radically generous with their wealth—reflecting a deeper, transformative faith. Keller draws from James 2 and other passages to highlight the essential role that one’s attitude towards money and possessions plays in the Christian life. He identifies three hallmarks of genuine faith: radical generosity, radical graciousness, and radical practicality.
Main Discussion Points & Insights
1. The Radical Scope of the Eighth Commandment
- Not just about theft, but generosity:
- Keller emphasizes that simply refraining from stealing does not fulfill the commandment; rather, true obedience is demonstrated through radical generosity (04:30).
- Quote: “A thief hasn’t stopped being a thief until he’s generous… To obey the 8th Commandment, you must be radically generous or you’re a thief. That’s what the Bible says.” — Tim Keller (04:50).
- Three economic perspectives:
- Capitalism: “Your money is your own to do with what you want.”
- Communism/Socialism: “Your earnings belong to the people, to deal with as the community needs.”
- Christianity: “Your money is God’s, and you must do with it as He directs.” (06:20)
- Quote: “Christianity says: The money you earn is God’s, and you must do with it as he directs… If that money is somebody else’s and you’re not generous with it as the owner directs, it’s robbery, it’s embezzlement.” — Tim Keller (07:30).
2. The Essence of Faith Shown Through Generosity
- Faith manifests in radical generosity, not mere belief:
- Real faith is inseparable from actions, especially toward the poor and those in need (11:15).
- Quote: “The way you can tell real faith, true saving faith, is that it inevitably leads to radical generosity.” — Tim Keller (11:50).
- Mercy is central:
- Mercy, especially practical and economic mercy, is used as evidence of authentic faith (13:10).
- He notes how early Christians bewildered Roman society by being generous not just to their own poor, but to all poor—making Christianity extremely attractive (10:45).
- Historical note: Emperor Julian complained, “Nothing has contributed to the progress of the superstition of these Christians as their charity to strangers. The impious Galileans provide not only for their own poor, but for ours as well.” (10:50)
3. Real Faith: Three Marks
Keller structures his examination of faith into three key characteristics (14:20):
a. Radically Generous (14:40)
- Mercy triumphs over judgment:
- On Judgment Day, mercy shown is proof of genuine faith; mercy withheld signals a lack of real faith (15:00).
- Faith in action: Faith without deeds is dead, especially when it ignores material needs (15:40).
b. Radically Gracious (24:50)
- Rich in faith, poor in spirit:
- Christianity and its revivals often flourish among the materially poor because they better recognize dependence—mirroring the believer’s total dependence on God (25:30).
- Quote: “Every person, in relationship to God, no matter how much money you have in the bank, is spiritually poor. You are dependent every minute for every breath on God.” — Tim Keller (27:14)
- True grace to others:
- Those who grasp God’s uncaused love become gracious to "messed up" people because they see themselves in the same position before God (27:50).
c. Radically Practical (32:00)
- Faith and works:
- Real faith is not sentiment but action. Addressing needs practically is essential; saying “Go, I wish you well” without helping is empty (32:15).
- Quote: “With all due respect, do you think when Jesus was on the cross…he was full of warm, toasty feelings toward us? No. But he loved us. He gave.” — Tim Keller (33:10)
- Encouragement in struggle:
- Feelings may lag behind actions; the desire for generosity and discomfort with selfishness is a sign of God’s work within (34:00).
- Practical next step: Start by giving “more” and look for opportunities to meet needs, regardless of exact amounts (34:40).
4. The Challenge and Hope of Being “Poor in Spirit”
- Entrance into the kingdom:
- Genuine faith requires recognizing one’s spiritual poverty and absolute dependence on God’s mercy.
- Prayerful exhortation: “Before you can be rich toward other people, you’ve got to be poor toward God… Say, I ask that you save me strictly because of the riches that are mine through Jesus Christ.” — Tim Keller (35:10)
- Assurance in God’s love:
- God’s love is not contingent on our performance, but on His free grace: “He loves me because he loves me.” (29:20)
Notable Quotes & Memorable Moments
- “A thief hasn’t stopped being a thief until he’s generous… You have to be radically generous or you’re a thief.” — Tim Keller (04:50)
- “Christianity says, the wealth that you have, you enjoy, and it’s yours to take care of as a trustee, but you must give it generously as your owner directs. That’s God.” (07:00)
- “The essence of faith is to be controlled by who God is, and that will show itself up in your attitude toward your money and toward your possessions and toward things.” (23:00)
- “You are dependent every minute for every breath on God. Sometimes only the really economically poor can see that.” (27:14)
- “I am not loved because I’m good; I will be good because I’m loved. My pride, my bad habits, my sins will all fall before his triumphant love—because he loves me, because he loves me, because he loves me.” (29:20)
- “With all due respect, do you think when Jesus was on the cross...he was full of warm, toasty feelings toward us? No. But he loved us. He gave.” (33:10)

Final Thoughts
Tim Keller’s "Rich in Faith" sermon challenges listeners to evaluate the authenticity of their faith by examining their generosity, graciousness, and practical care for others. He stresses that a Christian’s orientation toward their own wealth and material possessions is not a peripheral or optional issue, but central to the faith itself. Through historical examples, Scripture, and piercing illustrations, Keller calls his audience to become the kind of community that inspires wonder in the world—not through spectacular achievements, but through radical acts of mercy and love grounded in God’s own grace.
