Running a church, though rewarding, is tiring. Maybe even exhausting. Church staffs love our materials because we’ve got everything turnkey and ready-to-go. We certainly don’t mind when churches add their unique contributions to our challenges, but nobody on your church staff should ever have to start from scratch.

How it Works

Hundreds of churches have successfully launched Challenges across all denominations.

Why Launch a 40-day challenge in the Next Season?

Create a Time to Self-Examine

Our 40-Day Challenges offer daily, practical, clear, yet challenging next steps for people to not only examine where they are in their faith today, but to push them, by grace, through faith, to become even greater followers of Jesus. Our Challenges are simple in concept, but Challenging in practice and can be used to examine where we are in light of Jesus and come out stronger.

Churchwide Unity

You’ll be joining with tens of thousands of others across the nation, and even some internationally. The power of that many people living out their faith will be what gives Christianity the spark it needs for the future. Watch momentum, energy, and excitement build as the entire church encourages and supports one another in their pursuit to follow Jesus.

Done-For-You Church Campaign Kits

Your time is best spent shepherding and guiding your members through the journey. Rather than being buried in the logistics of running a 40-Day all-in church sermon series, we’ve done our best to take care of every logistical detail from promotion to completion. Included in our FREE library of resources for each 40-Day Challenge are small group materials, kids weekly curriculum, social media graphics, sermon manuscripts, a daily school curriculum and more.

What Church Leaders are Saying​

Red Letter Challenge | Your Trusted Source for Bible Studies & Books

“In an era where people are struggling with discipleship, diving into the words of Jesus is one of the best things you can do. I love how Red Letter Challenge makes it easy to get an entire church diving deeper into the teachings of Christ.”

Carey Nieuwhof

Founding Pastor of Connexus Church, Author and Speaker

“If you feel like you were made for something more or if you are tired of checking religious boxes, the Red Letter Challenge is for you! By challenging people to go back to the good news message of Jesus, I truly believe this will help you find the life you were made for.”

Mike Foster

Our congregation has used RLC resources in congregation-wide efforts three times over the last two years, from RLC itself in Lent and in Fall, as well as kids’ materials. We are convinced that these have allowed us to not only stay vibrant during the last 20 months of craziness, but we’ve seen folks more engaged in serving others as well as in generosity for God’s work. We love “sitting at the feet of Jesus!” And then getting out and living out His love!

We’re glad you asked. There’s a ton of them! Pastor and Author, Zach Zehnder, gives you 5 reasons why a 40-day church challenge could be right for your church in this short video. This is the first video of a FREE 10-part video series to help you determine if a 40-day church challenge is right for your church. Find the other videos on our get started page.

Great news! We have a FREE 10-part video series to help you launch a 40-day Church Challenge. We’ve had the privilege to work with hundreds of churches and have many best practices to share. For those churches that order 100 or more copies, you can schedule a FREE 30-minute Zoom with Pastor and Author Zach Zehnder.  Additionally, you can ask further questions by contacting us.

These are the 5 best times of the calendar year to launch a 40-Day Church Challenge.

  1. Beginning of Year: You can promote heavily in December and at Christmas and build some serious momentum in the new year.
  2. Lent: 40 Days prior to Easter: Many churches will encourage people to give up something for the 40 days of Lent. We love this practice, but also, we’ve seen many churches encourage their people not just to give up something, but to start something new as well. There is nothing better to start than putting the words and habits of Jesus into practice!
  3. 40 Days after Easter: After the big celebratory Easter Sunday, it’s important you follow it up with great momentum.  Usually a church will have an 8-week window open after Easter while families are still in school. A 40-Day Church Challenge can provide some turnkey resources that will keep momentum strong going into the summer months.
  4. Summer: While most churches decrease in attendance in summer months, a 40-Day Church Challenge is a great opportunity to start the summer with a jump, not a slump!
  5. Fall: Weekly worship attendance is normally at its strongest in the Fall. Launching a 40-Day Church Challenge in the Fall will provide momentum and energy for your church to sustain this high attended season.  We encourage a start time any time after the school session (Ideally the Sunday after Labor Day) is back and encourage churches to wrap up by Thanksgiving.
