Several years ago I took a group of teens through my discipleship booklet. In the first lesson I quoted Colossians 2:6-7 and used it as a foundation for our studies.
I explained to them the importance of building a firm foundation for our lives in Christ. I am excited to say the message and the discipleship booklet studies we did really sunk in and deep roots were formed.
