With a view toward making disciples and covenanting them to a local church, where they will be baptized in the name of the Triune God and taught to obey all that Christ commanded, evangelism is the articulation of the holiness of God, the sin of man and its wages, Christ’s accomplishment of redemption through His incarnation, perfect life, death, burial, and resurrection on behalf of sinners, and the proper response of sinners: repentance from sin toward God, and faith in Jesus Christ alone for salvation.
Here is a two minute clip I took from two seminary lectures Dr. Waldron gave regarding ecclesiology and evangelism:
