does Paul's testimony of Christ meeting him on the road to Damascus get more detailed each time ?
Not long after Paul was converted on the Damascus road he preached the following message to the Jews:
"And straightway he preached Christ in the synagogues, that he is the Son of God.....proving that this is the very Christ" (Acts 9:20,22).
At that time Paul had not yet received the gospel which he was to preach among the Gentiles. He wrote the following:
"But when God, who set me apart from birth and called me by his grace, was pleased to reveal his Son in me so that I might preach him among the Gentiles, I did not consult any man, nor did I go up to Jerusalem to see those who were apostles before I was, but I went immediately into Arabia and later returned to Damascus" (Gal.1:15-17; NIV).
When Paul received a gospel from the Lord Jesus on the Damascus road he immediately went to Damascus (Acts 9:6-8). But when he received the gospel which he preached among the Gentiles he went immediately into Arabia. That can only mean that two different gospels were preached during the Acts period.
