The Great Commission requires the church to make disciples.
Effective evangelism is inherent in the nature of the church.
And, in the New Testament model the fruit of evangelism must survive and mature. Surviving and maturing usually includes incorporation into the membership of the church. Congregations which have not brought new Christians into the fellowship of believers have been encouraged to review their commitment to the Great Commission and the effectiveness of the methods they are using. New members who come into the church from other denominations are also included in this grouping. Examination of the survival and maturing of the fruit of evangelism should include not only the numbers joining, but also a study of these Christians after they become a part of the church.
