For I want you to know, brothers and sisters, that the gospel that was proclaimed by me is not of human origin;
for I did not receive it from a human source, nor was I taught it, but I received it through a revelation of Jesus Christ.
You have heard, no doubt, of my earlier life in Judaism. I was violently persecuting the church of God and was trying to destroy it.
I advanced in Judaism beyond many among my people of the same age, for I was far more zealous for the traditions of my ancestors.
But when God, who had set me apart before I was born and called me through his grace, was pleased
to reveal his Son to me, so that I might proclaim him among the Gentiles, I did not confer with any human being,
nor did I go up to Jerusalem to those who were already apostles before me, but I went away at once into Arabia, and afterwards I returned to Damascus.
