Reading Galatians 1:11-24, NIV.
..the gospel I preached..not man made nor taught…received it by revelation from Jesus Christ (vs 12).
Thought: i.e why it can last or survive through thick and thin (sufferings, imprisonment), sunshine or drought; 110% committed. Not man taught but God taught like Jesus, directly from the grand MASTER of universe.
..God set him apart from birth…preach Jesus to Gentiles (vs 15,16).
Galatians 1:11-24, GNB
[11]Let me tell you, my brothers and sisters, that the gospel I preach is not of human origin.
[12]I did not receive it from any human being, nor did anyone teach it to me. It was Jesus Christ himself who revealed it to me.
[13]You have been told how I used to live when I was devoted to the Jewish religion, how I persecuted without mercy the church of God and did my best to destroy it.
[14]I was ahead of most fellow-Jews of my age in my practice of the Jewish religion, and was much more devoted to the traditions of our ancestors.
[15]But God in his grace chose me even before I was born, and called me to serve him. And when he decided
[16]to reveal his Son to me, so that I might preach the Good News about him to the Gentiles, I did not go to anyone for advice,
[17]nor did I go to Jerusalem to see those who were apostles before me. Instead, I went at once to Arabia, and then I returned to Damascus.
[18]It was three years later that I went to Jerusalem to obtain information from Peter, and I stayed with him for two weeks.
[19]I did not see any other apostle except James, the Lord’s brother.
[20]What I write is true. God knows that I am not lying!
[21]Afterwards I went to places in Syria and Cilicia.
[22]At that time the members of the churches in Judea did not know me personally.
[23]They knew only what others were saying: “The man who used to persecute us is now preaching the faith that he once tried to destroy!”
[24]And so they praised God because of me.
