One of the resources I have used at each church I have served is the HABITS production pack and Super Series. This resource gives you materials that can truly help your teens reach a deeper commitment to Christ by learning Godly HABITS. HABITS is an acronym for
Hang time with God (Quiet Time Journals)
Accountability with another believer (Back 2 Back)
Bible Memorization (Hidden Treasures)
Involvement with the church body (no resources)
Tithing commitment (Bank of Blessings)
Study Scripture (Rootworks).
I took things a step further and adapted the materials to a new acronym for our group-PRACTICE. There is a 6 weeks teaching series on the HABITS along with everything you need to reproduce the take home materials for you teens. It’s a great investment and I’ve used it several times.
