God calls us to maturity as Christians, and this is often described simply as following Christ (e.g. Romans 15:5). A Christian disciple is a follower of Jesus. Our task as a church is to help one another to obey Jesus in everything just as he taught us.
Therefore go and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age. (Matthew 28:19-20)
