Barnabas was the Friend of the Suspected. When the Christians were fearful of Paul, the new convert, Barnabas recommended him to the brethren. When Antioch was moved under the preaching of the gospel, Barnabas was sent to investigate and make sure it was authentic. When Paul was for dropping John Mark as a companion, Barnabas took him and he turned out all right after all. There is a lot of suspicion among the brethren these days and we need more than one Barnabas.
