“Therefore, King Agrippa, I was not disobedient to the heavenly vision, 20 but declared first to those in Damascus and in Jerusalem, and throughout all the region of Judea, and then to the Gentiles, that they should repent, turn to God, and do works befitting repentance. 21 For these reasons the Jews seized me in the temple and tried to kill me. 22 Therefore, having obtained help from God, to this day I stand, witnessing both to small and great, saying no other things than those which the prophets and Moses said would come— 23 that the Christ would suffer, that He would be the first to rise from the dead, and would proclaim light to the Jewish people and to the Gentiles.” — Acts 26:19-23.
Paul goes on to say that he obeyed this vision, and proclaimed the gospel to Jews and then to Gentiles, telling them to repent and turn to God. In facing persecution, he affirms his trust in Christ crucified and risen from the dead, and that this message must be proclaimed both to Jews and Gentiles.
