Mentoring, not Discipleship. Mentoring is the growth a mentor encourages in the direction that the mentee chooses. Discipleship is the choice to pursue a life based on the design, principles, and teachings of another. In other words, a church member can mentor another church member. However, a church member should not be a disciple of another church member. Rather, all church members should seek to be disciples of God, as revealed in Scripture through the prophets and the writers, and especially through the teachings, the model life and the transformative death of Christ.
The risk of confusing mentorship with discipleship is that a disciple, by design, will replicate the discipler. Therefore, the church community exists to mentor each other as we make disciples of the Holy Spirit.
