Equipping the saints is the primary task of the pastor / teacher in the 'doing' of church. 

Ephesians 4:11-12  And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers,12 for the equipping of the saints for the work of ministry, for the edifying of the body of Christ,

As the church, body of believers, is built up they are then able to carry out the ministry God has designed for them.  The major problem in the church today is the lack of pastor / teachers who have a plan and ability to equip the saints for the edification of the body.  The heart of the process is teaching, not only the presentation of information, but the process of building it into believer's lives through a unified process.
