If you’re looking for a study to help your students get in the habit of spending consistent and meaningful time in God’s Word and prayer consider using this high school study from Jim Burns called Prayer and The Devotional Life: High School Group Study (Uncommon). The book walks students thru exercises and studies that help students learn about what the Bible says on how to communicate with God, how to pray like Christ, and how to develop the two practices into a discipline.
There are 12 total sessions here and the thing that I like the best is the fact that when you buy the study you also get the link to the PDF materials you can use with your group. You can make as many copies as you want. That’s awesome. Each study is broken into six sections. They start with a mixer to get the group familiar with each other, move to the message, dig into the passage, discuss application, reflect on the material, and close in meditation.
