After his baptism, Paul broke his fast and remained "certain days with the disciples which were at Damascus. And straightway he preached Christ in the synagogues, that He is the Son of God." Boldly he declared Jesus of Nazareth to be the long-looked-for Messiah, who "died for our sins according to the Scriptures; . . . was buried, and . . . rose again the third day," after which He was seen by the Twelve and by others. "And last of all," Paul added, "He was seen of me also, as of one born out of due time." I Corinthians 15:3, 4, 8. His arguments from prophecy were so conclusive, and his efforts were so manifestly attended by the power of God, that the Jews were confounded and unable to answer him.

Efter sin dåb afbrød Paulus sin faste og "blev nogle dage hos disciplene i Damaskus. Og straks begyndte han i synagogerne at prædike om Jesus, at han er Guds Søn." Frimodigt forkyndte han, at Jesus af Nazaret var den længselsfuldt ventede Messias, som "døde for vore synder, efter skrifterne, og at han blev begravet, og at han er opstået på den tredje dag," hvorefter han blev set af de tolv og også af andre. "Men sidst af alle blev han set også af mig som det ufuldbårne foster." 1Kor. 12,3-4. 8. Hans bevisførelse ud fra profeterne var så afgørende, og hans bestræbelser så øjensynligt bistået af Guds kraft, at jøderne blev forvirrede og ikke var i stand til at give ham svar.
