Galatians 1:13-16

By now you have heard stories of how severely I harassed and persecuted Christians and how systematically I endeavored to destroy God’s church, all because of my radical devotion to the Jewish religion. My zeal and passion for the doctrines of Judaism distinguished me among my people, for I was far more advanced in my religious instruction than others my age. But then God called me by his grace, and chose me from my birth to be his. He was pleased to unveil his Son in me so that I would proclaim him to the peoples of the world. After I had this encounter, I kept it a secret for some time, sharing it with no one.
