From John Piper’s article on “What is Discipleship and How is it Done?”
Every Christian should be helping unbelievers become believers by showing them Christ; that is, making a disciple.
And every Christian should be helping other believers grow to more and more maturity. That is making a disciple.
And every Christian should be seeking to get help for themselves from others to keep on growing. And that is also our discipleship. And every church should think through how all of these kinds of biblical disciple-making find expression in their corporate life.
