The Challenges
40-Day Challenges that Reignite Your Faith Journey
In just 40 days, your story could completely change. It starts by living a life like Jesus and doing what He says. Start your journey today.
The original RLC is a journey with Jesus’ words. Inside the bestselling Red Letter Challenge book is everything adults, youth, and kids need to go on a 40-day life-changing discipleship experience with Jesus.
Inside the Being Challenge book is everything you need to go on a 40-day life-changing journey to BE like Jesus. Along the way, you will learn and be challenged to practice the 5 keystone habits of Jesus.
Forgiveness can be challenging, but when you receive forgiveness the way Jesus intends, you enjoy a feeling of true freedom. The 40-day forgiving challenge focuses on 5 phases: sin, confession, absolution, restoration, and sanctification.
Why does it feel as if words like burnout, exhaustion, anger, loneliness, unhappiness, and anxiety are winning the day? The 40-day Serving Challenge is designed to lead you to more fulfillment than you ever thought possible.
Inside the Giving Challenge book readers will go on a 40-day life-changing journey learning and practicing how to be generous like Jesus, resulting in more joy than they ever thought possible.

What is Red Letter’s Story?
Red Letter Living was started by Zach and Allison Zehnder to create resources that are simple to understand, challenging in concept, highly practical, but always squarely aimed at Jesus. Christians can have good intentions all day long, but intentions without precise aim at exactly the One we are trying to be like, Jesus, will always lead to unintended consequences. God has been gracious to all, and being compelled by that grace, we believe that following Jesus is the single greatest opportunity of our lifetime!
