Only one kind of person will penetrate the world, and the failure of the church to produce this kind of person is the error that has thrown it into crisis. The crisis at the heart of the church is a crisis of product. What kind of person does the church produce? The Christ-commanded product is a person called a disciple. Christ commanded His church to “make disciples” (Matt 28:19). Jesus described a disciple as one who abides in Him, is obedient, bears fruit, glorifies God, has joy, and loves (see John 15: 7-17).
