Why Launch Our 40-Day Church Challenges?

Jesus-Centered

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.

“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!”
