Are you familiar with the concept of an apprenticeship? An apprentice is someone who wants to learn a trade and who learns from one who is engaged in that trade. They learn the ins and outs of the trade with the goal of becoming a master of that trade. Pastor Mark is teaching that the life of a Christ follower is much the same. We need to seek out those who are ahead of us in spiritual maturity, observe their lives and thus learn how to apply those spiritual principles to our own lives. This has been the pattern for spiritual growth since the founding of the church by Jesus.
