Acts 22:13,14

This sight was instantly restored; another proof that what had happened on the road was an actual encounter with God. Acts 22:14 Paul now begins to explain why Jesus had appeared to him. "The God of our fathers" Who was behind Jesus appearing to Paul. the God that his audience worshipped! The God that they claimed to be serving, the God that they would have argued they were defending against Paul's preaching. "Has appointed you to know His will" Which will include knowledge of the gospel message being given to Paul by direct revelation (Galatians 1:12). The inference here is clear, when Paul was persecuting Christians he was ignorant of God's will and he was acting contrary to such. will. "To see the Righteous One, and to hear an utterance from His voice" This statement reveals that Jesus of Nazareth is the Messiah and that the God of their fathers said so.
