When the Lord needed a man to receive and teach the truth to the zealous Pharisee Saul, who had “made havoc of the church, entering every house, and dragging off men and women, committing them to prison” (Acts 8:3, NKJV), he called on “a certain disciple at Damascus named Ananias” [Acts 9:10, NKJV]. For the nature of this special need, God did not call on any of the apostles, nor a local elder, nor even someone already known for his work as an evangelist. He sought a man who is simply registered in Scripture as “a certain disciple”.
