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.
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! You would be wise to connect with this resource and see what it can do for your church!
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.
What is unique about the Red Letter Challenge?
The Red Letter Challenge focuses on Jesus' commands to His disciples. As Pastor Zach Zehnder examined all that Jesus said to His disciples, he found five principles most important to Jesus: Being, Forgiving, Serving, Giving, and Going. We believe that helping people in these five areas will lead to incredible spiritual growth for the people in your church. For more about the RLC, go to this this link.
How will this increase small group engagement?
By having pre-made, quality small group study guides and videos, and following our promotion plan, we believe that your church will see significant growth in your small groups. Churches that participated in the RLC and followed our promotion/distribution plan see an average of more than 40% increase in small groups. One church even grew by 500%. Smaller churches that didn’t have small groups used RLC to launch their small groups, and even large churches saw growth many times over 40%.

When is the best time to launch a 40-day church campaign?
These are the 5 best times we've seen to launch a 40-day church campaign.
  1. Beginning of Year: You can promote heavily in December and at Christmas and build some serious momentum in the new year.
  2. 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 of Jesus into practice!
  3. 40 Days after Easter: You can promote heavily at Easter and really give your church something exciting to come back to the next week. Usually a church will have 6-8 weeks left after Easter while families are still in school and this can provide some great momentum going into the summer months.
  4. Summer: While most churches decrease in attendance in summer months, the RLC 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. Why not start the fall with a powerful 40-day church discipleship challenge? We encourage a start time any time after the school session is back and encourage churches to wrap up by Thanksgiving.
How do you suggest incorporating student ministry into RLC Campaign?
We believe that children and youth can and do have what it takes to put the words of Jesus and the principles of RLC into practice. In the past, we’ve seen student ministries (both middle and high school) interact very well with the RLC workbook and the small group components as well. RLC is a challenge in its practice, but not in its content. It is written in a simple-to-understand way that youth and adults can both understand.
How do you suggest incorporating kid’s ministry into RLC Campaign?
We’ve created a FREE weekly kid’s curriculum to be used on Sunday mornings for your kid’s ministry so that the kids are learning the same main principles as the adults. We have also written a companion RLC Kids workbook that targets K-5th grade. It mirrors the themes and days of the RLC workbook, but is written specifically with a K-5th audience in mind. Therefore, the devotions and the challenges are more kid-friendly. Also, based on how children best learn, there is an incredible narrative woven throughout the book to help kids engage with the principles of RLC even more. Because of its nature to challenge children, we do highly suggest parent involvement, no matter if it’s a 1st grader or a 5th grader.
Is Zach Zehnder available to speak at our RLC Campaign kickoff?
Zach does offer a limited number of Sundays to help churches kickoff their RLC campaign. Additionally, he has presented RLC workshops to churches as well on kickoff weekends. Fill out the Speaker Request Form with some needed information on our end and our team will get back to you.
