Galatians 1:15-19

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. And I had no desire to run to Jerusalem and try to impress those who had become apostles before me. Instead, I withdrew into the Arabian Desert. Then I returned to Damascus, where I had first encountered Jesus. I remained there for three years until I eventually went up to Jerusalem, met the apostle Peter, and stayed with him for a couple of weeks. The only other apostle I met during that time was Jacob, the Lord’s brother.
