Life-Changing 40-Day Experiences for Your Church​

Experience unity like never before as every person in your church is challenged to put the words of Jesus into practice!

Daily Challenges For All Ages


Turnkey, Free Church Resources

You should not have to reinvent the wheel with discipleship.

Leading a church the past two years has been tough to say the least. Keeping everyone on one mission with everything that is going on in the world, pandemic opinions (mask vs. no mask, vaccine vs. no vaccine) political tension, racial oppression, some saying you need to speak up here, or some offended you said too much there, wow...division is at an all-time high, and the church hasn’t been immune to this. Pastors, one of the wisest things you can do in divisive times, when noise is really loud all around you, is go back to the basics. Go back to the Good News. What unifies our church more than anything else? It’s Jesus. You shouldn’t have to spend hours searching for discipleship programs and Bible studies that you’ll have to spend days rewriting. Red Letter Living creates turnkey resources and sermon series for churches with proven results that are focused on the words, habits, and life of Jesus. Our 40-day challenges not only will teach Jesus-centered content, but will challenge every person in your church to take steps toward Jesus!

How it Works

Over 600 churches have successfully launched challenges across all denominations.

Transform Your Church

Focus on Jesus and not the little details. Sharing this journey will energize, unify, and transform both you and your church.

Why Launch Our 40-Day Church Challenges?


Jesus is the greatest disciple-maker in the world. Putting His words into practice helps people of all ages find the life God designed them to live. By staying focused on Jesus and the simple command to “hear and do” His words, we ensure a unifying experience for the whole church from beginning to end.

Practical Daily Challenges For Everyone

Everyone is personally invited to follow Jesus. Our challenges offer practical, clear, yet challenging next steps to help people of all ages grow in their faith. Watch momentum, energy, and excitement build in your church 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, and more.

Church Packs

From 10 books to over 1500 books we have a bundle that will will work for your church size.

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

“Leading churches are using campaigns to increase engagement in their community. Red Letter Challenge is not only a plug and play campaign to help your church gain a better insight into the teaching of Jesus but it will also help your church grow because of deeper engagement!”

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.

Zach does offer a limited number of Sundays to speak at churches. Additionally, he is a sought-after conference/event speaker. His topics that he excels in are discipleship, church growth, spiritual keystone habits, forgiveness, and anything related to his works. Fill out the Speaker Request Form with some needed information on our end and our team will get back to you.

We suggest at least a 4-week lead-in time with the books at your site.
