The conversion of Saul is a striking evidence of the miraculous power of the Holy Spirit to convict men of sin. He had verily believed that Jesus of Nazareth had disregarded the law of God and had taught His disciples that it was of no effect. But after his conversion, Saul recognized Jesus as the one who had come into the world for the express purpose of vindicating His Father's law. He was convinced that Jesus was the originator of the entire Jewish system of sacrifices. He saw that at the crucifixion type had met antitype, that Jesus had fulfilled the Old Testament prophecies concerning the Redeemer of Israel.

Saulus omvendelse er et slående vidnesbyrd om Helligåndens underfulde magt til at overbevise syndige mennesker. Han havde sandelig troet, at Jesus fra Nazaret havde ringeagtet Guds lov og lært sine disciple, at den var uden betydning. Men efter sin omvendelse erkendte Saulus, at Jesus var den eneste, der var kommet til verden for at hævde sin Faders lov. Han var sikker på, at det var Jesus, som havde skabt hele det jødiske ofringssystem. Han forstod, at ved korsfæstelsen havde forbilledet mødt virkeligheden; at Jesus havde opfyldt de gammeltestamentlige profetier om Israels Frelser.
