While it is true that Paul the Apostle was once involved in persecuting Christians, many people trust what he said because he underwent a profound transformation after encountering Jesus on the road to Damascus. His life-changing experience and subsequent commitment to spreading the teachings of Christ demonstrated a sincere change of heart and purpose. People believed in the authenticity of Paul's message and trusted his words based on the profound impact his encounter had on his life and the positive contributions he made to the early Christian movement. His story shows the redemption and grace offered to us by God's love, and Paul's testimony is proof of that. Thank you for your comment.
