Answer: He helped spread Jesus' teachings to gentiles.
Explanation: The Apostle Paul was one of the most deserving of spreading the teachings of Jesus outside of Israel, known as the Apostle of the Gentiles. He did not write anything of the Old Testament, although before he became a Christian, he was a fierce persecutor of Christians. On his way to Damascus, when he had the task of persecuting Christians, he was enlightened and became a fiery Christian. He wrote many articles in the New Testament and with unusual fervor preached and spread the teachings of Christ throughout the Mediterranean among the gentiles and showed great skill in that missionary work.
