Witness
Witness: Sharing the good news of Jesus Christ. “And the Lord added daily those who were being saved” (Acts 2:47).
That Luke indicates their conversions took place “daily” indicates that evangelistic activity was taking place on a regular (even daily) basis.
The “evangelist” is one imparted with a spiritual gift to complement the gifts of apostleship, prophecy, pastoring, and teaching (Ephesians 4:11). But the evidence from the early Christian literature shows that this title is rare. From its inception, Christianity was a lay movement. As early as Acts 8, we find that it is not the apostles, but the “amateur” missionaries, those evicted from Jerusalem at the hands of persecution following Stephen’s martyrdom, that took the gospel with them wherever they went. Paul reminds Philemon that in order to have a full understanding of his faith he must be active in sharing it (Philemon 6).
Methods of evangelism varied (to those in Athens Paul spoke as a Greek philosopher, to those in Antioch he reasoned as a Jew), but the message remained consistent with the apostolic teaching.
The literature of the second and third centuries is surprisingly silent concerning the every-day evangelistic practices of those lay-Christians which provided the bulk of the activity. This does not mean that there was no evangelism taking place. Churches existed in second-century locations where no missionary activity is recorded in the New Testament. Though little is mentioned by way of voluntary, spontaneous missionary activity past the New Testament, evangelists most certainly spread the gospel and won converts for the Kingdom.
